Computer Hardware

For it to be an input device, the requirements are for the user to be able to input information into a device or computer system. (keyboard, mouse)

Output devices need to show and display information aswell as produce information. (monitor, printer)

A touch-screen mobile phone would be a good example for an input/output device, you touch the screen to get it to do something, at the same time you gather the information from the screen.

Devices for communication between computers, such as modems and network cards, typically serve for both input and output.

Also, a touch screen can be considered as an input and output device. Others include: Fax, 3-in-1 printers, headsets, and audio/video cards.

Most still have 1. Some will still have 2, but they are being phased out. I have not yet seen a PATA-less motherboard, but they are definatley on the way, if not already here. That said, 4, 6 and 8 SATA ports are common, and support is good.

If you have legacy devices you need to connect, SATA->PATA devices are made, and fairly cheaply, too.

I think your new to the system

if at all the cmos battery is gone when ever you start the system you can see the system that it directly goes to the bios setup and asks you config the system time,date, need to setup so because of this system will be waiting in that position .

if not it will be asking you to press the "F1" or "ESC" key on your keyboard

It is just like every other sector on a hard disk, an area to store data, except for the fact that it contains the MBR (Master Boot Record).

in this year, it the cheapest are in about 50-100 dollars ....the expensive one are nearly thousands of dollars

BIOS (Binary In Out System)

Yes, it's. You have to purchase either a PCI wireless card (you will have to open the computer case to install it) or USB wireless adapter (which is easier to install, just put it one of usb ports).

The birth place of the computer is actually Iowa. The world's first electronic digital computer was actually built on the Iowa State campus by John V. Atanasoff, a professor of physics and mathematics.

The main components are:

Motherboard - the 'brains' of the computer - holding the CPU, memory and various sockets and chips.

RAM - the temporary 'memory' - which is wiped when the power is turned off

Hard-drive - a mass-storage device containing all the computer programs the user wants to use. It's contents are not wiped when power is turned off.

Optical drive - an input/output device that can be used to read data from the computer to be used on another machine - or be used to load programs onto the computer.

Video card - to provide an image for the operator to see what the computer is doing.

Power supply - which steps down the mains to a more usable voltage for the computer to use.

There are other minor components - but those are the main ones.

No. CDs are of lesser capacity than that of DVDs. Also if the computer drive is just a CD-Writer drive and not a DVD writer it will not burn DVDs.

3.0 GHz Pentium 4s were manufactured for both Socket 478 and LGA775.

I believe you are asking for fun facts about the CPU? Anyway, a few off the top of my head:

32 bit CPUs can only process 32 bits of data per cycle (64 bits can process 64 bits per cycle likewise). Fortunately most CPUs today clock over 2 billion cycles per second (2GHz). Some can do double that but they are very expensive.

CPUs can only do simple arithmetic operations, such as add, subtract, and move data. Multiplication and division is too complex and take multiple steps inside the Arithmetic Logic Unit (part of the CPU... it's very complicated).

norton updates every 5-15 mins has really good detection rates mcafee updates every day good detection rates ca updates every day poor detection rates norton is the better one out of the three but prevx is better

Just buy them with cheap price and test them by yourself.

Presently touch screens and voice recognition are classed as input devices as they require human interaction

Input device

Because anybody can open a website and put some things on it. How do you know you can trust them, if you don't know them?

Take nobodies word for anything. Research from many sources, note where the source came from and their aggenda.

Form an opinion, based on many sources of information.

The internet lends itself well to those, who want to remain hidden, in disguise or deliberately misleading. Use it with care.

Unless you live near a major seaport and have been victimized by a cruel coincidence, I'd say it is a common phenomenon known as "water hammer" and easily fixed. Water hammer is from ordinary vibrations in copper pipe supply lines. It is never noticed when the piping is properly braced and isolated. Check with a plumber or your hardware store expert if you think you can do it yourself. Ask about "hammer arrestors" as well.

USB 3.0 (sometimes known as USB SS) is significantly faster than USB 2.0 as it has 8 pins instead of four, allowing for theoretically double data bandwidth.

It is backwards compatible with USB 2.0 and USB 1.0 also.

An unpatched copy of Mac OS X will not install on a standard PC. There do exist cracked versions of Mac OS X that will allow you to install it on a select variety of PCs. WikiAnswers does not provide any information on how to patch OS X, nor any information on how to install it on a non-Apple branded computer.

I don't think so. A DVD burner is necessary to burn a DVD. DVD or CD-rw drive could not burn DVD. And if you use a CD burner to burn DVD, when you play it, you will discover that only the audio is available, you can't get the picture.

Permanent storage device such as a hard drive.

There are some basic files which are needed to load in the RAM for booting the system.

Coming to your question, All the boot files are loaded in the RAM while starting up the systems, and this information is temporary in nature. this information destroys everytime system shutdown.
