Securing Your Wireless Home Network Using 19216811
Quite often users skip the security part when they are setting up their home network. Knowing the risks of having an unsecured network we have to think more about it and actually take some steps. When it comes to securing your home network the default IP address 192.168.1.1 can be used effectively. Most of the security tweaks can be done in the Configuration panel and as you already know you can access it by typing 192.168.1.1 into the address bar of your browser. Once you get there you can do the following to increase the security of your home network.
Change your SSID. If a person who wants to break into your home network knows your SSID we can say that he is already one step closer to doing it. Use the IP address 192.168.1.1 to access your Configuration panel and change your SSID into something more unique. At the same time SSID broadcast should be turned off.
Change the default username and password. Many users feel secure with the default settings and leave them like that. However it is strongly advised to change the default username and password. This is the first step on making your network more secure.
Enable MAC address filtering. It should be enabled as another layer of security. If you use it with wireless encryption, your home network security will be brought to a completely new level.
Enable strong encryption. Select and use the strongest encryption the wireless devices in your network support. This can be easily done in the Configuration panel and you can use the IP 192.168.1.1 to access it. WEP encryption will require from you to change your password on let's say, a monthly basis. In order to prevent someone to crack your password always use numbers, capitals and special characters in your passwords.
Enable your firewall. The firewall on your router and other PCs in the network should be turned on. You can easily configure your firewall by accessing the Configuration panel and of course you can do that with the help of 192.168.1.1 IP address. By turning on the firewalls you can be sure that your network is completely safe from network intrusions.
Disable Auto-connection. Although this security measure has nothing to do with the IP 192.168.1.1 it is still worth mentioning. Your wireless device will try to connect to an open wireless network. When this is done the security is very low. Check if you have any enabled connections and disable them.

Learning To Speak Computer Language
Most businesses today need to take advantage of technology in order to maintain a certain level of success. If you own a business that uses computers, it is important for you to make sure that everyone that is within your business is up-to-date on the latest information about those computers. This is true when it comes to operating the computer properly as well as being able to surf the Internet safely without having to worry about viruses and spyware being problematic. It also is important for you to understand how to speak computer language, as that is becoming an art form that is very frequently overlooked within the business community.
The first thing that you should understand about computers are some of the basic terms that are used in order to talk about the computer properly. Rather than thinking you are dealing with a lot of technobabble, it's important for you to understand the basic terms so that you can speak to somebody about your computers intelligently. One of the reasons why it may be necessary for you to do so is if you are having problem with the computer and need any type of repair done. It may also be necessary for you to speak a computer language properly during any type of IT recruitment, as you would want to ensure that you are getting individuals onto your IT team that understood computers very well.
It may also be necessary for you to take some type of computer based training so that you can properly inform your employees as to how they should be using the computers on a daily basis. If you have ever heard the saying that something is only as strong as the weakest link, that is especially true when it comes to a computer network. If somebody that is working for your company is acting recklessly online, it is likely that problems are going to occur that will cost you both time and money. By educating your employees properly about the use of the computer, particularly when it comes to using it online, you will save yourself quite a bit of frustration.
Along with learning about computers and the technical terms that are necessary to speak about computers intelligently, it is also important to make sure that you are updating your equipment regularly. Of course, it is not going to be necessary for you to keep up with the absolute latest in technology, as that is continually changing. What is necessary, however, is for you to ensure that all of the software that is running on your computers is updated regularly. If any type of a patch is given for a software that you are using, be certain that you install it as soon as possible. The same is also true for any updates for antivirus or anti-spyware programs that may be operating on your computers. By updating those programs regularly, you will help to ensure that you are keeping your computers as safe as possible from all the latest threats that may be in the world.

Forensics For Technology - What Is It?
Forensics technology has become a broad field of investigation that refers to the scientific evidence used in criminal cases. This physical evidence is comprised of scientific collection, and its analysis. There are many new aspects of this type of technology geared toward evidence or establishing facts to be used in civil or criminal proceedings.
One of the technical areas that have much to offer is digital software. Criminals and terrorists have the opportunity to use a wide variety of electronic devices in their crimes. As crimes with a digital component are on the increase, it is necessary for law enforcement to have the equipment to counter these crimes. Digital forensic software has the capacity to recover data from a computer that has been reformatted or repartitioned
Other applicable software programs:
• A program capable of wiping a hard drive clean
• A spy type of software can locate hidden partitions, plus, quickly process large hard drives, and more.
• Images can be compresses into "flat" images from floppy disks for analysis
• A "partition manager" that examines all partitions on a hard drive and can switch them around or even hide them
• A new write blocker program protects computer information more effectively than past programs
The science which interprets image content is forensic image analysis. Several companies have produced efficient equipment that cut cost and speed up investigations. The equipment is designed to do comparison photography, analysis the content, photogrammetry (using photographs to make measurements) and to authenticate the image. Through a variety of techniques, mega data, pixil aspect ratios,and errors are utilized to extract information from video, photographs and animations. This is effective even when an individual has attempted to clock the evidence.
One of the newer tools is video forensics, which is primarily the scientific examination and evaluation of multimedia evidence in legal matters. The goal of this technology is to produce an accurate picture of evidence for a judge and jury to help determine the verdict in a civil or criminal case. In addition, this technology uses processing techniques to enhance video footage, refine grainy photographs, and to enhance a particular person or an object in a video footage, plus it converts digital video into specific formats for forensic analysis. This type of work is important in solving cases for law enforcement, security, surveillance and even military operations.
Data recovery is a process used for legal purposes to retrieve data from computers. It is much more difficult to erase all the information from a computer than most people realize. The purpose of data recovery is to retrieve lost or deleted information. The mined data is done using a process of collection, analysis, and then preservation. With the successful completion of these steps the computer expert will have the lost data to present to the court. This technology may be used in civil or criminal proceedings to provide evidence for the court.
If forensic describes evidence that can be used in court, then it also must cover the technology and science necessary to provide this evidence. A forensic investigation is conducted in a lawful manner, establishing facts and evidences that have been thoroughly examined, keeping in mind the chain of custody, to be presented in a courtroom. Subdivisions that exist under this area of investigation are firewall forensics, database forensics and mobile device forensics.
As demonstrated in this article, forensic investigation for technology is a very broad, technical body of scientific investigation utilizing state-of-the-art equipment, along with well-trained technicians. This type of technology has grown and will continue to grow due based on demand.
Identifying Mule Accounts
When there is fraud then there is mule account; in fact it is the more important than botnets or phishing methods because what will hackers do with the banking credentials they have if they cannot use them. It is an important part in fraud and fraudsters will look for ways just to recruit and also control the mules.
Today, mule recruitment is carried out in the internet by using scam. Fraudsters will send a false email about job searches saying that the victim's resume was reviewed and that they are suitable to work at home. Due to the fact that the economy is rough and it is an opportunity, victims will take the bait. In the next e-mail exchanges, victim will sign fake paperwork and receive instruction for his assignment. Sometimes mules will be told to accept funds from the compromised accounts, reshipping of goods that are bought using other person's credit card or even receiving the money.
Soon the fraudsters stumbled upon a problem, when potential recruits are asking about the company website. To fix the problem, fraudsters even built their own website as the front of their activities and candidates can view the site and see the vacancies. They made it look like a legit company by listing current employees and their jobs; details about their work and others.
Online mule recruitment has changed the way fraudsters operate because they don't need a physical presence in that country so that they can recruit potential mules. Since he is doing his recruitment online, he can further increase the number of mules to increase his profit. It has become a challenge for many law enforcement agencies and incident response teams of industries because the mules thought that they have legit jobs. Sometimes, even mules become victims as well.
Sometimes there are places where online recruitment may become a problem, thus fraudsters will still recruit mules in real world. Sometimes, these mules can be accomplices who know that they are working with fraudsters and they can open multiple banking accounts. Another type of mule is what police call as the vacation or tourist mules; mules who are flown to different country and opens accounts in certain banks for their operation.
Somehow it is difficult for banks to stop a mule in opening a banking account because mules can be like any other regular person who is trying to open a bank account. However, it is still possible to identify a potential mule and stop them before they make any wrong mistakes that they will regret. Since mules can either be accomplices who are trained liar or unwitting victims who are too willing to make money. Identifying the first one can be difficult but the second one is not.
Identifying unwitting mules can be very easy by asking simple question before they can open bank accounts. It is the same as security screening found in airports, where weird sets of questions are asked; questions that are not designed for liars but for certain individuals who were duped and place into a particular situation.
For example bank employees will ask the individual whether someone else told him or her to open a banking account in this bank; or asking if opening this particular bank account is related into a particular job offer he or she received on the internet or even in the real life. Or any other questions that would raise an alarm for the bank, but it doesn't mean that the employee can truly assess if that person is a potential mule or not. In fact the answers will be recorded and opening the bank account will be put on hold until further results from the investigations made by the incident handling or security team is available.
Basically, banks do not need to perform additional special training for their employees, a simple information campaign regarding new procedures will do. Customer education is really not that important at all, but it won't hurt the bank if they will try like giving away fliers or posting ads that explains the danger of mule scams would help. Instead, banking clients and the public will appreciate the information given by banks and can help deter frauds in recruiting more mules.
The International Council of E-Commerce Consultants (EC-Council) is a member-based organization that certifies individuals in cybersecurity and e-commerce. It is the owner and developer of 20 security certifications. EC-Council has trained over 90,000 security professionals and certified more than 40,000 members. These certifications are recognized worldwide and have received endorsements from various government agencies. They also offer incident response training.

MS Outlook Tip: How to Automatically Organize Incoming Emails
The Ford Model T assembly line is often cited as a world-changing example of productivity. Outlook rules may never have that honor but it's a great productivity tool if tweaked properly. Outlook's rules can truly serve as an assembly line for all your incoming email management tasks.
Think of rules as traffic cops who direct and move (email) traffic and streamline the flow. Rules are specific sets of instructions that are applied to messages under a specific set of conditions. Rules are applicable for messages as well as RSS feeds.
All Outlook rules broadly are of two types "" those that deal with organizing your emails by moving it around and those that notify you when some action occurs.
The best things about rules are that they can be selectively applied, applied in combination, automatically run or even run manually. Think about it, in the absence of rules, we would have had to spend considerable time sifting through the emails by hand one at a time.
One of the most often used application for rules are when you want to organize emails in Outlook and move emails to a folders automatically as they land in the inbox. The obvious benefit of shunting emails automatically is cleanliness and organization. The rule is best suited for mails which arrive frequently - like newsletters, email updates or feeds. Such mails are usually kept in "˜storage' for later reading.
So, creating personal folders for such mails are the first thing, creating a system to automatically organize those emails into these folders is the next.
1. Setup a folder or folders for saving the emails (e.g. Job, Family, Pals, and Newsletters etc).
2. You can create a rule directly from a message. Right-click on the email you want to automatically move to the special folder. Click on Create Rule.
3.In the Create Rule box that opens up, you can select one or more conditions and the follow through actions by checking the boxes. As shown, you can screen the email by sender address (or distribution list), subject and/or recipient. You can also set a sound alert or a desktop New Item Alert for the incoming mail. To move the email to a specific folder, checkmark Move the item to folder. Click on the Select folder button to select the folder or click on New for a new one.
4.Click on OK to confirm the new rule. All emails satisfying the new rule will get moved automatically to the folder from now. If you instantly want to run the rule, check Run this rule now on messages already in the current folder.
5.Further fine-tune the rule if you want by clicking on Advanced Options. The advanced option wizard lets you select other conditions, select a range of actions to perform on them and select exceptions to the rules if any.
5. So, thought of interesting plays with the rules? Let's see... you can move mails with attachments to another folder but with an exception that it's within a set size range. Another good use is to assign a priority level to incoming mail so you can deal with the more important ones first and leave the rest for later.
Alternatively, instead of selecting a single message to start a new rule, you can also start create a rule from scratch using the wizard by opening it from Tools "" Rules and Alerts "" New Rule.
In Step 1: Select a template. Under the entries of Stay organized, select Move messages from someone to a folder.
In Step 2: Edit the rule description "" click on the underlined link for people or distribution list to set the From address filter. Next, click on the specified folder link to set the target folder.
The next sequences of steps are the same as in the Advanced Options wizard.
Many interesting automatic actions can be performed on your emails with a combination of different rules. Remember, rules are performed in sequence as shown in the Rules and Alerts box. Rules can always be edited at any step and also their order changed.
Key Steps to Lessen Your Chances of Getting Hacked
Having your computer hacked is a disturbing problem for any internet user. It has been estimated that around 75% of all breaches have been the result of external threats. However, it is becoming very difficult to keep your personal details secure due to advanced hacking techniques. Recently, even Google accounts have been easily hacked through cleverly-crafted HTML emails. Online users should be even more careful when using computers at internet café centers (Wi-Fi areas) because advanced hacking software is capable of recording all of your movements.
According to latest web incidents hacking reports, most hackings are carried out using two strategies; SQL injection and cross-sire scripting. As technology grows, hacking techniques are becoming more and more advanced. Hence, it is important to know smart ways in which to secure your personal details with less fear of being hacked.
Here are some key steps that will help lessen the chances of getting hacked:
First and foremost, when you are using computers that are not secure, don't log into email or bank accounts. Instead, use a highly secure personalized computer to perform online transactions.
Next, create a strong password:
Passwords that are simple and taken from a dictionary can be traced more easily by the hackers. Advanced hacking tools are now available to crack the password in no time. So, you need to create passwords that have a minimum of 12 characters and are difficult to trace. Creating your password by combining numbers can also be more powerful than passwords that consist of just characters.
Never type out your password:
"Key logger" is a tool that can record all the keystrokes from an infected computer. So, eliminate typing your password and paste it instead. To do this, type the password onto a notepad and copy and paste when your password is required.
Avoid entering passwords on websites without https:
Unsecure websites have just "http" tags and not "https" in which the "s" stands for secure. If you enter details on websites that are not https, your data might easily be hacked without your knowledge.
IP-address protection:
You can also install IP-address protection software which allows access to the sites you have added to your list. This can prevent unwanted sites or software from obtaining access to your accounts.
Secure your computer:
Enhance the security of your computer by installing high quality antivirus software that is powerful enough to prevent malicious programs from accessing your computer details. Regular updates are a must to update your computer's security from a wide range of virus or Trojans that are created on a regular basis.
These are just some of the important steps to take that will assist you in lessening your chances of getting hacked computers.

Why Passwords Are Exposing Us to Insider Crime
Millions going missing in SA
R5.5m was stolen from the education department in Mpumalanga via password and sign-on fraud in August and September last year. Bank details of genuine beneficiaries were changed on the department's Basic Accounting System and several payments of between R864 000 and R989 000 were channelled to seven other accounts
In March this year, it was reported that stolen passwords were used to divert funds from the Social Security Agency into personal accounts and three people were arrested for fraud in Esikhawini, KwaZulu-Natal.
In the same month, three officials in the marine and coastal management branch of the department of environmental affairs were suspended for allegedly diverting donor funds into a private account
Passwords: the root of all evil?
Controlling system access and managing passwords is a big headache for IT departments. It is frustrating, time-consuming and costly. Aside from the persistent admin problems and costs of passwords, we write them down, put them on sticky-notes, share them, pop them into our phones and even keep them on spreadsheets. Driven by the need for speed and convenience, this happens every day in offices all over the country.
But passwords also leave the door wide open for insider crime and the increasing damage it is causing.
Just how damaging can insiders be?
IT-based insider crime is all bad for the bottom line. Insiders modify data to enrich themselves, their families and friends. They steal data and sell it to others. They're often bribed by outsiders to alter data and frequently they vandalise or 'publish' sensitive data because of a grudge against the organisation.
Some of the common dangers are as follows:
Fraudulent paymentsModifying data such as credit records, licences, identity docsProperty theft via fraudulent invoices, delivery notes / addressesSabotage: data vandalism and the ensuing costs of IT downtime, recovery and restorationReplace passwords with biometric sign-on: Department of Agriculture, Forestry and Fisheries
One South African organisation taking the issue seriously is the Department of Agriculture, Forestry and Fisheries which implemented a password replacement solution in 2009.
Within the Department, the Budgets & Reporting Directorate manages financial control systems. This includes controlling sign-on to PCs and secure applications used by finance, HR and supply chain management.
For years, passwords had created problems for users and system controllers. With sign-on credentials for the Government's transversal systems, including BAS, Persal and LOGIS, changing every 15 to 30 days, there was a high incidence of forgotten passwords, resulting in lockouts and wasteful downtime. Resetting passwords also placed an unnecessary burden on help desks, diverting the technical support team from more productive tasks.
An audit of password procedures and risk revealed that staff were writing down their passwords and the proximity of workstations meant users could see each other's passwords when they were being entered. By installing a product called SuperSign with Sagem desktop fingerprint readers, all passwords - from initial PC sign-ons to credentials for accessing each application - were replaced with fingerprint sign-on.
As well as enhancing security, there are no more lockouts stemming from confusion over which password goes with which application and SuperSign has eliminated password queries for all biometric-protected applications.
Fingerprints control IT sign-on at the Department of Home Affairs
To end IT-based fraud around ID documents, Home Affairs is introducing this sort of biometric-based security. In April this year, the department said that it was tackling internal corruption and that biometric sign-on is being implemented.
Minister Nkosazana Dlamini-Zuma said that, "We want to identify who was involved at every step of the process - a definite paper trail, so if there is an allegation of corruption, then we can deal with it." The minister said that 3 833 employees within Home Affairs have been enrolled onto this biometric system so far.
The perception of detection: the biggest deterrent to insider fraud
In June this year, the US Association of Certified Fraud Examiners (ACFE) released its 2010 Report to the Nations on Occupational Fraud and Abuse. The report is based on a study of 1,843 cases of insider fraud from 106 countries between Jan 2008 and Dec 2009.
The researchers reckon that the typical organisation loses 5% of its annual revenue to fraud. Applied to the estimated 2009 Gross World Product, this translates to a potential global fraud loss of more than $2.9 trillion.
According to ACFE founder, Dr Joseph T. Wells, "In most organizations the accounting department is the place where controls are most strongly enforced, and yet we're still seeing more fraud there than anywhere else. This shows that traditional controls alone are insufficient to keep occupational fraud from occurring. A large part of the reason is that accounting department employees are more likely than just about anyone in the company to be familiar with the controls and how to develop methods to circumvent them."
"Saying that there is deficient internal control when fraud occurs is much like saying that when there is a fire, heat is present: it doesn't tell us much that we don't know. While controls are necessary, that isn't what really deters fraud; it's the perception of detection. Succinctly stated, those who perceive that they will be caught committing fraud are less likely to commit it."
Insider fraud: a solution at your fingertips
According to the ACFE study, insider crime remains impervious to traditional controls - most fraud is still only detected by accident or tip-offs. Scarcely more than 1% of the insider fraud was detected by IT controls. However, in 20% of the cases, internal controls were overridden by the fraudsters.
Biometric sign-on offers a compelling solution by linking IT users to their transactions, creating a definitive audit trail of who did what, where and when.

Spider Webs, Bow Ties, Scale-Free Networks, And The Deep Web
The World Wide Web conjures up images of a giant spider web where everything is connected to everything else in a random pattern and you can go from one edge of the web to another by just following the right links. Theoretically, that's what makes the web different from of typical index system: You can follow hyperlinks from one page to another. In the "small world" theory of the web, every web page is thought to be separated from any other Web page by an average of about 19 clicks. In 1968, socologist Stanley Milgram invented small-world theory for social networks by noting that every human was separated from any other human by only six degree of separation. On the Web, the small world theory was supported by early research on a small sampling of web sites. But research conducted jointly by scientists at IBM, Compaq, and Alta Vista found something entirely different. These scientists used a web crawler to identify 200 million Web pages and follow 1.5 billion links on these pages.
The researcher discovered that the web was not like a spider web at all, but rather like a bow tie. The bow-tie Web had a " strong connected component" (SCC) composed of about 56 million Web pages. On the right side of the bow tie was a set of 44 million OUT pages that you could get from the center, but could not return to the center from. OUT pages tended to be corporate intranet and other web sites pages that are designed to trap you at the site when you land. On the left side of the bow tie was a set of 44 million IN pages from which you could get to the center, but that you could not travel to from the center. These were recently created pages that had not yet been linked to many centre pages. In addition, 43 million pages were classified as " tendrils" pages that did not link to the center and could not be linked to from the center. However, the tendril pages were sometimes linked to IN and/or OUT pages. Occasionally, tendrils linked to one another without passing through the center ( these are called "tubes"). Finally, there were 16 million pages totally disconnected from everything.
Further evidence for the non-random and structured nature of the Web is provided in research performed by Albert-Lazlo Barabasi at the University of Notre Dame. Barabasi's Team found that far from being a random, exponentially exploding network of 50 billion Web pages, activity on the Web was actually highly concentrated in "very-connected super nodes" that provided the connectivity to less well-connected nodes. Barabasi dubbed this type of network a "scale-free" network and found parallels in the growth of cancers, diseases transmission, and computer viruses. As its turns out, scale-free networks are highly vulnerable to destruction: Destroy their super nodes and transmission of messages breaks down rapidly. On the upside, if you are a marketer trying to "spread the message" about your products, place your products on one of the super nodes and watch the news spread. Or build super nodes and attract a huge audience.
Thus the picture of the web that emerges from this research is quite different from earlier reports. The notion that most pairs of web pages are separated by a handful of links, almost always under 20, and that the number of connections would grow exponentially with the size of the web, is not supported. In fact, there is a 75% chance that there is no path from one randomly chosen page to another. With this knowledge, it now becomes clear why the most advanced web search engines only index a very small percentage of all web pages, and only about 2% of the overall population of internet hosts(about 400 million). Search engines cannot find most web sites because their pages are not well-connected or linked to the central core of the web. Another important finding is the identification of a "deep web" composed of over 900 billion web pages are not easily accessible to web crawlers that most search engine companies use. Instead, these pages are either proprietary (not available to crawlers and non-subscribers) like the pages of (the Wall Street Journal) or are not easily available from web pages. In the last few years newer search engines (such as the medical search engine Mammaheath) and older ones such as yahoo have been revised to search the deep web. Because e-commerce revenues in part depend on customers being able to find a web site using search engines, web site managers need to take steps to ensure their web pages are part of the connected central core, or "super nodes" of the web. One way to do this is to make sure the site has as many links as possible to and from other relevant sites, especially to other sites within the SCC.

Computer Forensics, Computer Crimes, and Data Recovery
Computer Forensics
Computer forensics is the science of obtaining information from computers and digital media. This information is usually intended to be used as legal evidence. The aim of the computer forensic analyst is twofold. First, he or she must retrieve data from the computer discs and other digital media in question. Then the data must be stored. It must be stored in a manner that is safe and that allows the analyst to affirm that it was found on the original device. A computer forensics specialist must be expert in both the technology of data recovery and the legal aspects of evidence handling.
Computer Crimes
Computer forensics is a relatively new science. Before the 1980s, there were no personal computers and therefore no computer crimes. Now computers figure in a wide variety of illegal activity, both directly and in the form of an information storage medium.
There are some crimes in which computers are directly involved. One of these is hacking into corporate and government websites. Hackers may try to obtain information like customer's credit card or bank account information. They may try to embarrass government agencies and prevent the access of citizens by shutting down websites or posting false information. Another crime is that of abuse in chat rooms and social media sites. This may take the form of bullying, encouraging others to attack a person or spreading false information about someone to damage their reputation.
In other crimes, the computer is not used in committing the crime itself. It is used to store information that may be used as evidence of the crime. This might include journals of criminal activity, spread sheets with financial information or emails.
Another category of computer crime might be considered to be one in which the computer is not absolutely necessary for the crime, but makes it much easier and more likely to be committed. Crimes of this nature might include storing child pornography or attempting to solicit meetings with minors.
Data Recovery Techniques
The main mission of the computer analyst is data recovery. There are several techniques that might be used:
Live Recovery - If the computer is seized while it is still running, or is shut down but operational, live recovery may be used. This may involve searching the hard drive of the computer using the installed operating system or third-party software.
Deleted File Recovery - Many people do not realize that when files are deleted from a computer, they are seldom actually removed from the hard drive. When the delete function is used, all this does is remove the file's location from the computer's file location list. Software is available to recover these files in most cases. Even if the hard drive has been erased, the data is often still there.
Steganography - This is an interesting method of hiding data in which the information is mixed into an image. The data may also be intermixed with the coding of a computer file.
Computer forensics is a fascinating science. Its practitioners must be part computer expert, part evidence handling specialist and part detective.

What You Need to Know About AC Adapters for Laptops
AC adapters for laptops could sometimes be the first one that is going to give out. If you have a laptop, basically, all of its parts are sturdy in construction except the adapters. Adapters are the first ones giving out because of the wire and the careless use of some owners.
The AC adapters are known to charge the battery of the laptops. Without the adapters, your laptop's 2-4 hour battery capacity would have been nothing. Depending on how you use the AC adapters, it could even protect other parts of the laptop from wear and tear.
Aside from charging the battery, it could also be used directly to power the laptop. If you see most people conserve the life of their laptop's battery by removing the battery pack when it is at home and instead using the adapter, this is among the many ways on how the adapter helps to sustain durability of the other laptop parts.
The problem with AC adapters for laptops is the fact that they differ from one brand to the other. This means that if you happened to have problems with your adapter, what you need to do is to go to the manufacturer and buy a new one. But the trouble with these things is the fact that they are so expensive. The fact that there is a specific laptop charger makes it just that.
There are many ways in order for you to take care of your adapters. One, you need to know that the function of the adapter is to charge the batteries. If you are going to use your laptop, it is highly suggested that you make sure to plug it to the suggested current. For the US made laptops, they typically require 110V.
The problem with this kind of charger is the basic premise that you need to have a transformer. If you are not going to have a charger, plugging it in to the 220V outlet especially in Asia may bring you trouble. It could affect your batteries and your adapter. Typically today, the manufacturers created an auto volt system which allows chargers to be used from 110V to 220V.
Always read the manual first before you even use the laptop. There are times when the warranty wouldn't cover for such instances. You need to be careful when you are dealing with electronic items.

Rather than sitting in the office all week and being associated with little more than hard work, a home server will be a permanent feature of your household. Like other permanent features, your home server will give visitors to your home a certain impression about you - and if you want to make sure that impression is good, you will also want your home server to look good.

1. Windows
No, we don't mean the operating system, silly.

This will show off the internal components of your computer, and pave the way for your more interesting modifications.
2. Lights
There is something very appealing about adding extra lights to your pride and joy. Just as car modders will often add undercarriage lighting to their creations, so case modders will often add LED lights to their computer cases. You can pick any colour you want, and apart from space restrictions inside your case, you are pretty much free to put them wherever you like.

Emergency Notification Systems
Technology is growing faster than the world is turning. How do I know this? Because as a video forensic expert, I am on the front lines investigating new technologies and systems as they are implemented in law enforcement communities.
I recently came across a public safety system manufactured by a company called Nice Systems. Much like the Pelco systems, Nice Systems are capable of doing much more than only capturing audio and video recordings of predetermined coverage areas.
If a municipality has installed a Nice System in their community that includes intricate sensors and cameras connected to 911 call center software, those sensors and cameras can notify 911 dispatch minutes before any person can make a call to that same call center. This reduces emergency response time.
For example, let's say that a busy intersection has the Nice Systems equipment installed. An accident occurs at that intersection. The equipment will automatically notify that area's 911 call center of the accident seconds-if not minutes-before any person can place a call to that same call center.
This equipment is saving lives and will continue to improve technologically, keeping us forensic experts on our toes. It is the forensic expert's job to understand how this equipment works and to use that knowledge to help the courts better understand evidence presented in a litigation that was created on this high tech equipment.
I recently reviewed an operator's manual for a type of Nice System call center software to confirm some aspects of a case I have been assigned. The details of the manual are astonishing and the capability of the software is extremely advanced. Law enforcement officials have to spend time learning how this equipment functions so that they can maintain and operate the system to their advantage.
Sure, it takes more time and tax payer money, but this technology actually saves lives and solves crime. The time and expense are worthwhile.
As an audio and video forensic expert, not only do I have to research new systems that I receive evidence from, but I also help litigators understand the limitations and capabilities of these highly technical emergency notification systems so that the evidence created by these systems can be properly addressed by the courts. The bottom line is that as forensic experts, we never stop learning and growing in order to keep up with technology. When we learn, we help others learn as well.
The Uses of 19216811 and Its Importance
The most famous broadband router manufacturer Linksys uses the IP 192.168.1.1 as a default IP address for the routers they produce. This IP address is also used by numerous other router manufacturers. This IP is used to access the configuration options of the router and at the same time it can help us troubleshoot some networking problems like loss of connectivity, or restoring the password for your home network.
In this article, we want to help you understand better what an IP address is, how private IPs work and what are default IPs. So let's get started.
IP Address - What Is It?
The term IP is used to represent a sequence of numbers usually used by devices like routers, personal computers, and so on, when they have to connect to a local computer network. When we take a look at the numbers of an IP we can see the following. We call these numbers octets because there are 8 different positions. Every single position can be 1-on or 0-off and there are 256 possible combinations. This applies for only on octet ant as you can see there are four of them. Some of them can't be used as IPs and belong to the restricted addresses. For example:
• 255.255.255.255 - network broadcasts
• 0.0.0.0 - default network address
• 127.0.0.1 - loopback address
Private IP Addresses - How Do They Work?
The IP address 192.168.1.1 is a so called private IP. These IP are mainly used in local networks ( school LAN, business LAN, etc). Computers with a private IP are not able to connect to the Internet on their won. For that to be possible they have to use a NAT. The entire system can be applied in the different direction, too. A computer which is not part of the network cannot identify or connect to another computer that is in a network. All the connections must go through a NAT or Network Address translation. NAT is often used as an additional security measure which is completely justified if we taken into account the constant increase of the number of threats on the Internet today.
Default IP Address - What Is It?
Default IPs are used in private networks. The most popular is 192.168.1.1 but there are others too like 192.168.1.0, 192.168.1.2, 192.168.1.254 and so on. The main reason why these IP are used is to make it easier for new users to access their network router configuration utility and set it up or solve networking problems.
