Computer How To

If I told you that there was one fairly simple thing you could do, that once set up you'd rarely even have to think about it and that it could save you from almost any computer related disaster, would you be interested? Such a thing does exist: it's called backing up. If there were anything close to a magic silver bullet for recovering from almost any computer related problem, backing up religiously would be it. Consider, for example: your computer becomes infected with a virus you can't get rid of. Recover by simply restoring your machine to the most recent backup before the infection. you accidentally delete a file. Recover by restoring it from a backup. your computer's hard drive fails and must be replaced. Recover by restoring your most recent backup to the replacement hard drive. you install some new software that, as far as you can tell, completely messes up your system and won't uninstall properly. Recover by restoring your system from its most recent backup....

My computer was in shambles. I could not get anything done anymore. Everything was so slow; I did not know what the problem was at first. And then a friend suggested that I install XoftSpySE because he said there is probably some software that I got over the Internet that slowed down my computer, as this was the case with his before. So, I tried it out and found that I had a lot of spyware and adware in there that I never knew existed! Thanks to this wonderful product, my computer now works like new. I used to have trouble surfing the Internet before. Each time I would go into some sites to learn about a certain product or their features, this pesky pop-up window would not let me read anything anymore. It made me think they were made by rival companies or something. Every few seconds, it came around like a mosquito and it just made me so tired of the whole idea, so I end up just closing the window without getting anything done at all. After installing XoftSpySE, I read that it could st...

Peer to peer was originally used to describe the communication of two peers and is analogous to a telephone conversation. A phone conversation involves two people (peers) of equal status, communication between a point-to-point connection. Simply, this is what P2P is, a point-to-point connection between two equal participants. The Internet started as a peer-to-peer system. The goal of the original ARPANET was to share computing resources around the USA. Its challenge was to connect a set of distributed resources, using different network connectivity, within one common network architecture. The first hosts on the ARPANET were several U.S. universities, e.g., the University College of Los Angeles, Santa Barbara, SRI and University of Utah. These were already independent computing sites with equal status and the ARPANET connected them as such, not in a master-slave or client-server relationship but ratheras equal computing peers. From the late 1960s until 1994, the Internet had one model o...

What happens if you are unable to start your computer because the Operating System (OS) could not be loaded? This could happen when any file used for the booting process becomes corrupt or lost, or if your system has been affected by a virus. You need a set of clean files that will allow you to load the OS and access the file system and services in case your PC is unable to boot. Keeping a backup of the files critical to this functionality on a Bootup disk is good practice. Let us see what exactly happens when you turn on your computer - the BIOS is loaded first. Normally, the BIOS runs some tests on the system hardware at startup, after which it locates a bootable device on your computer (Floppy, CD-ROM, Hard disk) and the Master Boot Record (MBR) is loaded into the memory. The MBR locates the active partition and loads the boot sector into the memory. The boot sector has the code to start the bootstrap loader which then loads the OS (Windows, Linux, Unix, MacOS) into the memory. In c...

If you're having some strange problems with your computer, it could be that the power supplied to your machine from your wall outlet is dirty. Or perhaps you could been the recent victim of a power surge or spike during a hydro-blackout, or storm. Power surges occur, when too much hydro-is transmitted down the line even for just a nanosecond or so. It can often be caused by other electrical units connected to the same circuit. Sometimes a computer may not have enough power, due to a heavy draw from other items such as air conditioners. Fortunately the solution to this problem. What you need is an uninterruptible power supply, commonly known as the UPS. This basically introduces a middleman/protector between your computer and the Hydro coming from your wall socket. The UPS plugs into the wall and draws energy to charge a battery. The power from the battery, as I use the power your computer. By adding this extra step, power surges, power sides and blackouts will have little effect on...

Buying a Computer is the first step that anyone must take to join the Computer and Internet Revolution. Buying a computer is like buying a car, approach it the same way see it as a big investment because buying a computer is a relatively infrequent process for most people. However, purchasing the accessories that go along with them happens more often than most of us would like so it needs to be taken into consideration when researching the available products. Computers can do much more than you think and will be a significant part of everyone's future. Computers vary in price according to how powerful and functionality and have become an integral part of our everyday lives, from basic typing to shopping on the internet. Computers are here to stay so everyone should consider learning how to perform their own pc upgrades and minor repairs. Computers are like cars: faster is not automatically better, they are complex systems and looking at one feature while ignoring the rest is not an...

There are three reasons why you would want to DIY Computer Repair... A lot has been said over the years about DIY or Do It Yourself. Why? Why would you do it yourself? Good question, most of the time you will get this as an answer: Save Money! Yes you defiantly will save some money. Is that all there is to it though? Really? Is there some other compelling reason to do it yourself? Maybe, If you are the type of person that gets a good feeling, or an ego boost when you do something and it turns out very well. Then again you maybe the type of person that doesn't want someone else to do the task because no one can do it as well as you can. What if you are new to the idea of doing it yourself? Where would you find the information to do the task? There are a lot of places to get the information such as a library, the local book store, or on the internet. What if the information is spread across all these places instead of one place? Then you spend more time looking for the information to...

Where wireless routers and speeds are concerned, price is not always the best controlling factor. There's a wide variety of wireless routers available in the market and one is not always as good as the other. Basic, low-range types gives you speeds of only about 56 mbps. Pick one with ultra-range capabilities or a dual-band router for best performance and fastest speeds. Setting up your wireless routers is not as difficult as it seems. When you have a wireless router at hand, you only have to substitute your DSL or cable connection with it. For techie people who would like to learn, here's a quick guide to doing it yourself. First, remove cable or DS modem from your power supply and also the ethernet cable from the computer. Leave the phone cord on the modem. Connect the end of the ethernet cable you removed from your computer to the internet port at the back of your router. This port is normally marked clearly. Plug your modem back to the power source. Plug one end of your rou...

A while back I talked with an ophthalmology practice administrator. We spoke about the issues with communicating between offices electronically. My colleague operates a practice with one location that was considering installing a LAN using the Internet. However, the doctors had reservations about giving their employees access to the Web. What the practice needs to ask themselves is this: what kind of network do we plan to have in the future, and how much bandwidth will it require? 'Bandwidth' has several definitions that depend on the context. Is it optical physicals, radio communications or a data transfer across digital communication systems? In this article, I refer to the latter definition. Regardless of whether your practice uses a single LAN or has many office locations, there's a limited amount of data that can be transmitted between any two computers. This data transfer can be thought of like water flowing through a pipe. In general, you can transfer more water (the...

I'm sure people have gotten pretty creative in their attempts to monitor pc activity. The reasons people feel compelled to do this vary quite a bit; however, the main reasons have to do with safety to some degree. In line with this idea is the desires of most to have their tracking efforts go unnoticed by the computer users. There are incognito ways to go about this, here are some more thoughts for you to consider. To monitor pc activity, you can do searches as an end user or check your computers information by hand. This rarely works though, because an internet browsing history is easy to delete; in fact, my computer has a program that cleans my history and deletes my activity each time I close my browser. At my business, I have an even more extensive program that protects client information and other business documents; including financials. I monitor activity on all my computers and advise others to do the same. It's not uncommon to have information stolen or abused; not to ...

Nowadays regarding auction sites eBay is one of the largest on the Internet and the 5,000,000 members prove its popularity and rank against all the other auctioneer web sites out there. I imagine most everyone has either sold an item on eBay or purchased something at one point or another in their lives. But besides actually marketing and buying on eBay once in awhile, there really are individuals that actually make money from there household by operating on eBay and making money by doing so. These people have online home businesses that they utilize eBay for a full-time income. These people sell particulars normally at wholesale costs in large quantities and spread them out over eBay allowing people to "scoop up" those products. In most cases you will find more than one item for sale by the same individual people also are known to find sites that provide drop shippers and profit, some people actually attain really good money on eBay. Another thing I have seen done is an eBay ...

The round the clock "busy" tongue has been given a completely new and unique job to perform apart from doing chit-chats, differentiating sweet from salty, wiping off the melting cones etc. It has been turned into a computer control pad for a below neck disabled. Though sounds extremely amazing, it has to be believed if it claimed by Georgia Tech researchers. The researchers at Georgia Tech have come up successfully to transform the mouth of a disabled into a virtual computer which would be controlled by the tongue. Interestingly, his thirty-two teeth, even if he/she has the complete set intact or not, will work like a keyboard. The innovation, though in its early stage, has shown bright results, and seems to have brought an end to all the woes of a disabled. They call it "Tongue Drive System." As the name implies, the tongue has the lead role to play to serve a disabled. The simple and guided movements of the tongue will help him to run his wash machines and air-con...

A site-to-site virtual private network (VPN) allows you to maintain a secure "always-on" connection between two physically separate sites using an existing non-secure network such as the public Internet. Traffic between the two sites is transmitted over an encrypted tunnel to prevent snooping or other types of data attacks. This configuration requires an IOS software image that supports cryptography. The one used in the examples is c870-advipservicesk9-mz.124-15.T6.bin. There are several protocols used in creating the VPN including protocols used for a key exchange between the peers, those used to encrypt the tunnel, and hashing technologies which produce message digests. VPN Protocols IPSec: Internet Protocol Security (IPSec) is a suite of protocols that are used to secure IP communications. IPSec involves both key exchanges and tunnel encryption. You can think of IPSec as a framework for implementing security. When creating an IPSec VPN, you can choose from a variety of sec...

One of the most important parts of a business in the technologically advanced world of today is the data center. These centers house computer systems, storage systems, telecommunications, and more. Also in the center are often forms of environmental control, such as air conditioning to keep the area cool and fire control devices to keep the machines safe and running. The reason that these centers are so important is that they handle and store much of the data of a number of companies. This data could be operational, business, and customer related. Some companies develop their own data storage centers in house, but the majority use external companies and systems. This allows the company to focus on running the daily business operations without having to worry about the safety and storage of their data. Some of these centers deal with only the operations architecture of a company; others are more comprehensive. One of the largest and most common uses of a data center is for offsite data ...

Configuring our computers for our home computer network After all the hardware for our home computer network has been setup , we now have to setup our computers to allow communication with each other. Though we have our hardware in place it remains useless unless the computer knows what to do with it, and it is you who has to tell it what to do with the hardware. In this article we will go through the process of setting up the software side of our network, which is not very complicated, actually a lot of it is automated or semi-automated where the computer does most of the work. Some of the stuff you need to do is routine technical stuff like installing the drivers (software that controls the hardware devices like the NIC) on your computer. Also you will need to set up each computer so they are ready to share their files on your home network. Note for Wireless Users: If you are using a wireless router on your network then you will need to install the router first. Though installation p...

There is a dirty fact about Windows based computers that you may not want to hear, but unfortunately it is the truth, and it is something that you must deal with. Or maybe you are already dealing with it. What am I talking about? I am talking about a computer that runs slow. It takes forever for applications to load. Start ups and shut downs have slowed to a crawl. Your computer will freeze up and even crash at times. You get the blue screen of death. Why are these symptoms inevitable? It's because of the Windows registry. This database stores all kinds of entries and files Windows accesses whenever the computer user makes a command request. Also new files are added and left behind inside that registry, and that will eventually build up to a level that will spill over to other applications, which will make your computer get slow. I said earlier that this is inevitable. That's actually a half truth. All computers suffer from a registry that gets too big, but you can do something...

Each Event ID has a different meaning, like Event ID 454 suggests that the Information Store database has got corrupted due to any cause. In the description part, you would see different error numbers, through which the source of corruption and hence cure can be judged out: "Information Store (976) Database recovery/restore f th unexpected error Error Number With Event ID 454, the application wants to tell that there is a problem with the restore or recovery operation with the database. If Exchange Server has detected a missing file, any different version file or the corrupted files in the database, this Event ID can be seen. Now, with different Error numbers, you can find the culprit: Error 1216: During recovery process, when ESE attempts to bring all the databases in a storage group into a consistent process and finds a database missing, the error may be seen. So locate and restore the missing databases to the appropriate folder. Another cause could be the missing or replaced tr...

Personal computers have completely revolutionized the way the world, lives, works and conducts business. Strictly-speaking, computers arrived on the scene way back in 1936 when one Konrad Zuse produced what was then called the Z1 computer. This was a cumbersome machine that could perform simple calculations and also crunch simple data. This was not as sophisticated as what we have today but it served to set the foundation for further research and in 1944, John Atanasoff and Clifford Berry from Iowa University built on this model and produced several innovations of the computer which was capable of producing arithmetic calculations, parallel [processing, memory regeneration and other simple computing tasks. The research was taken further at Harvard University, then IBM, the business conglomerate joined the fray and in 1953 produced what was then the world's first sophisticated computer. Even then, it was still large, occupying entire floors and consuming untold power. As we have men...

If you see the message, "Your computer is infected. Windows has detected spyware infection", on your PC, be wary about installing just any anti-spyware software program. This could just be a clever way of tricking PC owners into downloading spyware into their computer system. Spyware programs, along with computer viruses, have become among the top Internet threats that PC owners and Internet surfers face. When one's computer system becomes spyware infected, one becomes very vulnerable to identity theft. Through these programs, it becomes easier for some malicious software developers to steal information about the PC owner. What makes this even worse is that new spyware programs are created every day, each one more sophisticated and more potentially damaging than the previous versions. Spyware can be a source of major computer trouble. Because it is, PC owners have to get themselves a reliable anti-spyware software program. However, if one's PC is not yet infected with...
