All computers currently available have similar components and functions. The obvious component is the System Box. This is most obvious in Desktop Computers. The system box used to be called the CPU - wrongly considering the confusion that caused. What the system box contains are things like a power suplly to power everything, the memory to do the work required and also to store the answers obtained fro the work, and the heart or mircroprocessor to actually do everyhing needed. The second component is the Screen to show you what information you are giving the computer, any message the computer needs to tell you, and the results the computer has come up with. The thrid component is the Keyboard to enter information into the computer, give the computer instructions on what to do with the information, and were to send the results to.
Usually the power supply.
Instruction Decoder
RAM
A multi-touch computer is one where you touch the screen to be in control. You touch the things you want to click on, You use two fingers in a pinching motion to zoom. It is a computer where you are more in control.
A computer component would be part of the computer itself. Devices can be separate to a computer and just connected to it.
A hardware device is a piece of physical computer technology, usually made of metal and plastic. The word is used in contrast with software, which refers to programs which direct the physical hardware to do things.
Software are programs. They originally came on floppies, which gives the term software. Software are the things you can't touch. Hardware is the hard drive, the computer, the things you can touch.
the computer component not tested by post rutine is the power supply
client/server application

soft ware supplies are things that you can see but don't touch the computer programs
Hardware is anything you can actually touch. Something you can kick when it makes you angry!The computer itself, keyboard, mouse, webcam, printer... Software is the programs, the data, the things you cannot see or touch physicaly...The stuff that's stored on the hardware! :D
