i want to know basic of computer hardware?

Question

in detail....

Answer 1

All computers have the same basic design, even the old ones I work on. There are three components, the processor which executes machine operators, the memory where program executables and temporary data files are stored and the IO portion which has your disk, keyboard, network stuff etc. The details are different for all vendors so your best bet is to get a book about it.

Answer 2

Well on a very very basic level, a computer is made up of a Processor and a hard drive, attached to a motherboard. The processor recieves information from the software installed on the hard drive. It then processes the information, and accesses whatever it needs from the hard drive. The process is much more complicated than this...however, I won't bore you with the details.

In addition to that, there are graphics cards, which display information on the screen. There are USB ports that allow information to be transferred to and from a periphreal of some sort, like a printer, or a Flash drive, or an external hard drive. There are Keyboard and Mouse ports, which allow for input from the user. There is a network card, which allows the computer to talk to other computers through a network. There is a power supply that provides power to the computer so it will work. There are cooling fans to keep things cool. There is a CD and/or DVD drive that allows information to be inputted,and to make discs in most cases of info stored on the hard drive.

A programmable machine. The two principal characteristics of a computer are:
- It responds to a specific set of instructions in a well-defined manner.

* It can execute a prerecorded list of instructions (a program).

Modern computers are electronic and digital. The actual machinery -- wires, transistors, and circuits -- is called hardware; the instructions and data are called software.

All general-purpose computers require the following hardware components:
- memory : Enables a computer to store, at least temporarily, data and programs.
- mass storage device : Allows a computer to permanently retain large amounts of data. Common mass storage devices include disk drives and tape drives.
- input device : Usually a keyboard and mouse, the input device is the conduit through which data and instructions enter a computer.
- output device : A display screen, printer, or other device that lets you see what the computer has accomplished.
- central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions.

In addition to these components, many others make it possible for the basic components to work together efficiently. For example, every computer requires a bus that transmits data from one part of the computer to another.

Computers can be generally classified by size and power as follows, though there is considerable overlap:
- personal computer : A small, single-user computer based on a microprocessor. In addition to the microprocessor, a personal computer has a keyboard for entering data, a monitor for displaying information, and a storage device for saving data.
- workstation : A powerful, single-user computer. A workstation is like a personal computer, but it has a more powerful microprocessor and a higher-quality monitor.
- minicomputer : A multi-user computer capable of supporting from 10 to hundreds of users simultaneously.
- mainframe : A powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously.
- supercomputer : An extremely fast computer that can perform hundreds of millions of instructions per second.
