Parts of computer

There are five main types of components: (1) microprocessor, (2) memory chips, (3) input devices, (4) storage devices, (5) output devices.

Microprocessor also known a CPU - central processing unit. CPU consist of thousand transistors, different electronic components wires. There parts are arranged in circuits and built into a chip.

There are two group of circuits: (1) control unit and (2) digital logical unit somtimes called arithmetical - logical unit. Control unit directs and coordinates system. Digital - logical unit made calculations.

Computer used binary numeration system consist of "0" and "1". When circuits off, it correspondent to the binary digital "0", if on - binary digital "1".

Memory chips hold data and processing instruction for use by microprocessor. Like microprocessor memory chips consist of transistors, electronic components and wire.

There are two basic kinds of memory (1) ROM read only memory, (2) RAM random access memory.

ROM chips to hold instructions that computer runs repatedly.

RAM chips is main memory of computer, used by user, and can hold memory as long as power is an.

CPU and ROM are lokated on circuit board, kalled matherboard.

Other components come on MB colled cards. Cards can by plugget thruout slots inside computer, and ports, outside computer.

There are two main input devices (1) mouse (2) keyboard.

Mouse have a function to move cursor , and click on objekt that need.

Keyboard need for typing and input of commands.

Storage davices include HDD, CD(DVD)-ROM, flashrom. It used for data storege, usally.

Output devices printer and monitor. Printer take text and imagens from computer and print them on paiper. Monitor convert information, generatet by computer into visual information.
