Why your system is restarting itself?

It could be a lack of regular defragmentations, spy-ware and virus checks. If you have not done this on your computer on a couple of months this could be the problem.

It could also be virus related as in something new. Post on my board for more info. If you have an old operating system older than Windows 2000, that is another cause.

How long do computer warranties last?

Most computers come with either a 90-day, 1-year, 2-year, 3-year or 4-year limited warranty, depending on the product purchased. One-year warranties are the most common. You can also purchase extended warranties when buying a computer. For example, within the fist year of buying a Mac, you can buy AppleCare to extend it to two years.

How much free disk space do I need for optimum performance?

The only effect that free capacity has on performance is with regards to your paging, or "swap", file. Ideally, it should be between the same and ouble the amount of RAM you have installed on your computer. So if you have 2 GB of RAM, you'll want at least 2 GB free, although Windows may not need that much if you do nothing memory-intensive.

Why is it important to back up your hard drive from time to time?

if you receive a virus or any malware that disrupts your computers functions or stops you from accessing your files, or if the virus is made to delete your files it can disable you access to the info and you might need to reinstall your operating system in this case you would not be able to access your information unless it was backed up. you could also cause physical damage to your laptop or its stolen and unless its backed up you wont be able to access any of your files. Also you should do it time to time so that you are updateing you backed up files with any current files that you recently created

What is file backup and why it is important?

Backing up files means making copies of important files so you don't lose all of your work when something goes wrong (power outage, hard drive failure, stolen computer, etc.)

If you have never lost any important information and feel like you don't need to backup your files, you are in for a rude awakening when it eventually happens.

What type of computer problems are typically the most difficult to trouleshoot?

I would have to say their both about equal but it really matters to certain people. Software is mostly installing/uninstalling certain programs, drivers, etc while hardware might consist of re-soldering a new part on your motherboard.

Hardware is definitely the most costly though, make sure you get a lot of people's opinions about a computer malfunction before you go out and buy a new hard drive or ram sticks.

What role does data on CD ROM play in determining the speed of a computer?

The CD ROM does not have any affect on the speed of the CPU or the speed of the Frontside Bus. The CPU and Frontside Bus is what carries data and the CD ROM is not connected nor involved with the speed of the computer.

How do you setup cmos?

Most computers have a keystroke (usually esc, del, or F12) that will interrupt the boot sequence when you start your computer. In the past, this would be when the white text flies across the screen displaying memory available, hard disk sizes, etc. This will get you into the BIOS for "cmos setup".

CMOS is a type of memory that does not lose its data on power loss. In earlier computers, this is where the boot up configuration was stored; hence the phrase, "setup cmos"

How do you turn on the comptuer?

Hit BIG RED SHINY BUTTON. If you don't have a BIG RED SHINY BUTTON, hit the button in front of the comptuer.

Who is the father modern computer?

Can you use an ultra160 SCSI drive with a ultra320 SCSI controller?

Yes you can.

They will work fine. These statements "they are not designed to do this and would not do it well" WRONG and "Performance would be terrible and the drives would fail much sooner" also WRONG. U320 drives are backwards compatible and should work without issue on a U160 controller, the performance will be the same as a U160 drive and will not affect the drive's MTBF.

The drives will work fine !! The performance of the drives is NOT impacted at all --> they still rotate at the same speed; the seek times aren't any different; etc. The ONLY difference is that the interface speed is different (Ultra 160 vs Ultra 320). ... and it certainly has NO impact on the reliability of the drives !! [r.e. "... the drives would fail much sooner ..."].

... in fact, unless you're using an array which could support a sustained transfer rate higher than Ultra 160 speeds, the ONLY time there would be any difference in performance (compared to an Ultra 320 controller) will be in transfers to/from the drive's buffers => a very low % of disk operations.

Bottom line: Buy the disks you listed. They'll work just fine :-)

How many characters is one byte?

Long long time ago a character was only one byte. Now (unicode) a character is 2 or 4 bytes, but usually we use a variable-length encoding called utf-8.

Why have computers became an important research tool?

Over time, computers have become important research tools. First, they began to replace encyclopedias, maps, atlases, and microfiche with CD-ROM versions. Then as the Internet became popular, encyclopedias moved to a subscription format. That way, you didn't have to own a set of bulky encyclopedias, and the information would always be up to date.

Of course, the Internet replaces a lot of periodicals too and enables ordinary people to have access to medical journals, law books, newswires, and lots of other information. It also helps with more informal education too. If you need to access original research or niche information that few have heard of, you will likely be able to find it online.

Why your laptop is running so slow?

First, make sure there are no unwanted background processes such as spyware. They can take your system to a crawl speed. Use a tool such as spybot to detect and remove spyware. Next, make sure all of your anti-virus software is up to date and that you have all of the definitions current. Last, make sure you have enough physical memory. Loading a lot of applications can tie up memory and you can end up "swapping" a lot of data to disk and that takes time.

When troubleshooting a computer hardware problem which tool might help you?

Some troubleshooting tools for Windows are Microsoft Fix It Solution Center and Windows Error Lookup tool or WELT. Two others are WinAudit and Joeware Utilities. These tools are all free to use.

What are the steps in the POST process?

Basically: CPU is checked, then the system clock, the chipset, the slots, ports, and other on-board devices. Next is the video check. Up to this point all errors are communicated via beep codes as there is nothing on the monitor. You can simulate this by removing the RAM chips and listening for the error beeps. After the video check, RAM is counted, the keyboard is checked, the drives are checked, and all the information found is compared to what is stored in CMOS. If it matches, POST turns boot over to the OS. Otherwise, an error message is displayed.

What is parking of Hard Disk head?

It places the drive head in a position that is least likely to cause damage to the drive if it is removed or moved physically.

What is the most important job of the bios?

The entire boot of your system is done with BIOS. BIOS loads up PS/2 connections which is typically your keyboard or mouse but most people are upgrading to USB keyboards and mouses. BIOS also boots up your harddrive which is turn boots up your Operating System.

What are two methods for keeping track of screws during assembly so that reassembly goes more smoothly?

One effective method for keeping track of screws during assembly is to use labeled containers or trays to sort screws by type or location, ensuring that each screw can be easily identified and retrieved later. Another method is to take photos of the assembly process at each stage, capturing the placement of screws, which serves as a visual reference for reassembly. These strategies help maintain organization and reduce the risk of losing or mismatching screws.
