Processing of Computer

Processing of Computer

1. Input.........Computer work computers that are part of the required information and directions, the portion of the input. That all hardware device is transmitted through the Internet at information, that all the hardware devices as input device.
For example : keyboard, mouse, scanner, document reader, light pen, digital cameras e.t.c.

2.Control unit....Computer inside the control unit,s all managed through an automated process to work. Receive data from a keyboard or other input unit,s, it can be determined where the information inside the computer, through which parts of the computer,s data to be processed, the data will be processed after the work is to define and control the operation.

3.Arithmetic logic unit....Arithmetic Logic unit usually all logical and mathematical function. It consists of various types of electronic circuit.
Arithmetic Logic Unit via a control program to add, subtract, multiply, divide. The program may decide.

4..Memory option..........There are two types of memory main memory, secondary memory, namely :
The main memory........There are two types of  main memory RAM and ROM. RAM is usually connected to the motherboard.This called primary memory.
Secondary memory.......Many types of secondary memory.   For example..........Hard disk, Pain drive, CD, DVD e.t.c.

5..Output operation......Output device through the computer,s  result,s we can learn. CPU via the output device is connected with the output port.

Part OF Computer

1. Main memory
                                         ......The information is stored in the computer,s main memory is. The two memory-type, such as ROM and RAM are associated with different microprocessors through the bus.
2. Arithmetic logic unit
                                                          .....Make this parts of the process for mathematical problem solving, reasoning and decision Mulch is committed to work. This part of the Microprocessor inside.
3.Control unit
                                   ..........This part of the computer,s controls to various parts of the bus through the coordination and control of all activities.
4. Input device
                                    ..........I entered the information and data via computer. Keyboard and mouse input device. Living is not associated directly with the computer,s. Use the keyboard and bus interface circuits.
5. Output device
                                        ..............Computer inside the unit,s output data sent through the name of the output device. Them to be connected to it via the interface circuit.
6. Microprocessor
                                              ..................An electronic chip microprocessors. Microprocessors and other electronic device with a micro-computer to use it. The central part of the process of microprocessor say Micro-Computer.

What is computer?

Computer is a iron box. When installed program then it is a programmable machine.Computer is a set of electromechanical device, which can sense electrical signals and logic. It can process this electrical signal according to the logic. It have three part that Input, Output, CPU.
