Don’t Throw Out Those Old Computers – Use Linux!

Monday, October 25th, 2010

The average computer user just doesn’t know enough about computers to compare operating systems to determine which will run most efficiently and provide the most security, so our only gauge for what works is simply what everyone else is using. We live in a world where Windows and Macintosh rule, therefore we don’t even give Linux a second though. But we should! Linux is free, reliable and it runs extraordinarily well on old computers with little processing power. It just makes sense to use it, particularly if you work for a non-profit which relies on older, donated computers to operate.
Why You Might Want to Consider Using Linux
Linux is an operating system just like Microsoft Windows and MacOS on the Macintosh. Computer experts know it well and most of the Internet’s infra-structure is managed by Linux computers. But most desktop computer users have never heard of it. There are a lot of benefits to using Linux:

It is free. Windows costs money. So do MacOS upgrades.

It is easy to install. It is every bit as easy to install Linux as it is to install other software. Some Linux installers even allow you to run Linux off a CD, so that you can try it out on your computer without affecting anything else on the machine.

It is incredibly secure. Because Linux is open source, even if there were a widespread virus released today, there would be hundreds of patches released tomorrow, either by ordinary people that use the operating system or by the distribution maintainers. With Windows, you have to wait for a patch from a single company all while having to pay extra for virus protection software.

It is extraordinarily reliable. While Windows computers might go a day or even a week before needing to restart, people often have Linux systems running for years without fear of the system crashing.
It is very efficient. Unlike Windows and Macintosh, Linux does not require big disk drives, huge amounts of RAM, and a super fast processor. What this means is it can run incredibly well even on old, underpowered computers. So, while you may not be able to run the latest version of Windows on those donated computers, Linux will run easily and quickly. In fact, Linux is so efficient that it can pretend to be a Windows server more efficiently than Windows can be a Windows server.

What’s Stopping You?
With all of these benefits, it just makes sense to use Linux! Some national governments and lots of universities have standardized on Linux for years, but the general public is a little more hesitant. So, what’s stopping people? Here are some of the most common reasons (none of which really hold up):
It is complicated and uses all sorts of weird cryptic commands
This is true if you install it without a graphical user interface (GUI), but that’s completely your choice. Most desktop users would prefer to install Linux with a GUI since it makes it more user-friendly. In fact, you can customize the GUI to look much like Windows and Macintosh computers, so five minutes of orientation is all you will need to be fully productive.
Everyone else uses Windows
Probably the biggest concern people have is that if they use Linux, they will have trouble sending and receiving emails and files to computers that use Windows because they are different operating systems, but that’s simply not the case.
Because Email protocols are standardized, email from any computer (Windows, Macintosh, or Linux) works with email on any other. Files are no problem either, since Linux supports all the standard file formats.
Also, consider the fact that Windows 98, Windows NT, Windows 2000, Windows Server 2003, Windows XP, Windows Vista, Windows Server 2008, Windows 7 are all different operating systems, all in common use, and far from compatible with each other.
There is no support
This has never been true. The open source community supports Linux very well and if you need to talk to someone on the phone, you can buy support packages from lots of different companies. The most well-known of these is Red Hat.
Word and Excel don’t run on Linux
This is true, but OpenOffice does. OpenOffice is free and it does everything Microsoft Office does and more. At Sumac Research, although we use Windows, Macintosh, and Linux computers, we use OpenOffice on all of them. It doesn’t matter which computer you use, the documents work the same on each. OpenOffice can also open, edit and save Word, PowerPoint, and Excel documents.

A checklist for second-hand computers

Monday, August 23rd, 2010

It is very important to check a used computer thoroughly before buying it because it can cause problems in the future. A hard drive will not show any outward signs, but may deteriorate. Similarly the needle can suddenly slip and may cause scratches on the disc, ultimately leading to loss of memory used computers can fail any time. If they are checked, errors that may occur can be known. Let us first consider the possible defects that can occur when buying a used computer. hard drive failure can occur due to heavy wear over time. The heads read and write to a disk drive are used to retrieve or recode the data stored on the hard drive using a disk platter rotates at high speed. Over a period of time without failure or malfunction of disk increases. bad sectors of hard disk can be found that if an area full analysis is done on the computer used. The scanning time depends on the capacity and size of the hard disk of the computer used. Many skip this procedure because of the long process of scanning the entire disk and end up buying a computer is used with a bad sector. Monitors must be checked for defects. The malfunction of a monitor is called a joint “dry” which means the monitor does not work after preheating. This can be done only if the monitor is made to work for at least 20-30 minutes after ignition of the computer. Next is to look for potential opportunities of the central processing unit freezes. Normally, all the CPUs of a fan and heat sink unit to maintain freshness. Over a period of time fans can not function properly due to the accumulation of dust and dirt causing an overheating CPU and even lead to termination of operation. Although buying a used computer fan must be checked and if no abnormal noise is heard, it is not good for the purchase. The computer used can have a greater opportunity to obtain crashed and froze because of the use of the operating system for many years. There may be a cache or RAM fault due to exposure to courses leading to loss of data. To increase the performance of the computer and to avoid crashing, the operating system on the computer can be reinstalled with a new operating system or another. While controlling the computers used for defects, it is good to disconnect if no network connection present before testing. In addition, it is advisable to check the discs such as CD or DVD by their opening and closing and also play something on readers to see how they work. Monitors used computers can be checked for resolution and brightness by trying different color options, settings and so on. To check the hard disk size CMOS setup can be lived and to check the CPU speed, cache memory and RAM on the pause button is pressed when it appears on the screen during the boot process. To check the boot process, the computer can be turned on and off several times and see how he reacts. Verification must be done to see if all the passwords are erased before buying a used computer.

A Checklist for Used Computers

Saturday, April 17th, 2010

It is very important to check a used computer thoroughly before buying it as it may lead to problems in the future. A hard drive will not show any outward signs but may be deteriorating. The same way the needle can suddenly slip and can cause scratches on the disc ultimately leading to memory loss as used computers can fail any time. If they are checked, the faults which may occur can be known. Let us first see the possible faults which may occur while purchasing a used computer.

Hard disk failures can happen due to heavy wear and tear over a period of time. The read and write heads of a hard disk are used to retrieve or recode data stored on the hard disk with the help of a disk platter rotating at a high speed. Over a period of time the risk of failure or malfunction of disk increases. Faulty sectors of the hard disks can be found out only if a full surface scan is done on the used computer. The scanning time depends on the capacity and size of the hard disk of the used computer. Many skip this procedure due to the time consuming process of scanning the whole disk and end up purchasing a used computer with a faulty sector.

Monitors need to be checked for any faults. The malfunctioning of a monitor is called a “dry joint” which results in the monitor not working after getting warmed. This can be checked only if the monitor is made to work for at least 20 to 30 minutes after switching on the computer.

Next is to look for any possibilities of the central processing unit getting freezed. Normally all the central processing units have a fan and heat sink for keeping the unit cool. Over a period of time the fans may not work properly due to the accumulation of dust and dirt resulting in over heating of the central processing unit and even leading to stopping from functioning. While buying a used computer the fan needs to be checked and if any abnormal sound is heard, it is not good for purchase.

The used computer may have a higher possibility of getting crashed and freezed due to the usage of the operating system for a good number of years. There may be a cache or RAM fault due to the over exposure leading to loss of data. To increase the performance of the computer and to avoid crashing, the operating system of the used computer can be reinstalled with a new operating system or a fresh one.

While checking the used computers for any faults, it is good to disconnect the network connection if any present before performing the tests. Also it is advisable to check the drives like the CD or DVD by opening and closing them and also playing something on the drives to see how they work. Monitors of the used computers can be checked for the resolution and brightness by trying different options of color, settings and so on. To check the hard disk size the CMOS setup can be gone through and to verify the speed of the processor, cache and RAM the pause button is pressed when it appears on the screen during the booting process. To check the booting process, the computer can be turned on and off a few times and seen how it responds. Checking should be done to see if all the passwords are erased before purchasing a used computer.

How to reset the BIOS password in Dell computers

Tuesday, March 16th, 2010

Know how to reset the BIOS password in Dell is now necessary for system administrators and even casual users. Avoid the problem by resetting your BIOS password in the correct way. Having installed a password in the BIOS of your Dell computer is an effective way to ensure security, and for those that share a PC, it is a necessity. However, when a password is the default setup when you buy the machine, most do not know how to disable it or change it. There are several problems that may arise, for example when the HD is protected and can be accessed by entering the password for Dell. In some cases a person may forget the password, making it impossible to access the Dell. Fortunately, there is a way to circumvent this problem, but it is important to understand some basic concepts to avoid error. The BIOS BIOS stands for Basic Input Output System. It is present in all PCs, not just Dell. It is one that starts processes such as keyboard, mouse, memory, video card, etc. In other words, this is the first application that runs when you turn on the computer. Because of the vital functions it performs, it is important that if you decide to reset the BIOS password Dell, you follow all instructions carefully. Resetting the password in a Dell Dimension PC The first thing you must do is locate the password and PIN 3 CMOS reset jumper. It is usually on the motherboard. If you have no experience in handling computer hardware, you should call a qualified technician to do the work for you. But if you want to do it yourself, open the case of Dell PCs, and carefully remove the plug from the jumper pins marked 1 and 2. Then put the cap on the number of pins in two and three. Wait about ten seconds, then change the plug on pins 1 and 2. If done correctly, you will be able to reset the password. Dell Optiplex For Dell Optiplex, you need to spend some time studying the manual dealing specifically with the presentation of the card system, as the process is more complex. The first thing you have to do is remove the password jumper. Ask your Dell User Guide in hand, for finding it can be difficult. When you find the CMOS jumper, pull it out gently. As for the Dell Dimension you must remove the jumpers from the pins first and second. Put them on pins 2 and 3. After a minute or two, you can put it back on pins 1 and 2. Again, it should be noted that resetting BIOS passwords on Dell computers are delicate process and should only be undertaken by experts. Most often, users, especially newcomers, should have a technician perform this task. If you think you can do yourself, you must be sure that you have passed on the schemas of the system. Also make sure you work in an uncluttered environment. It is too easy to lose sight of these riders.
