1. hardware (Hardware) hardware components of a computer that can include electrical circuit. The monitor, printer, etc., which can break boards khi basic hardware is a major unit 4.1.1 the unit receiving data or input (Input Unit) serves the information and programs into the machine with the key figure structure, 1.3, including keyboard, mouse, Boris ruet, or scanner. Digitizer card swipe machine, etc.1.2 central processing system or CPU (Central Processing Unit CPU:) Act to work according to the instructions that appear in the program. At present the CPU of the PC microprocessor known as the (Micro Processor) or Intel Pentium Chip, for example, the company is, or is part of the Celelon company, AMD K7 (Athlon) K6, etc. Microprocessor. Is responsible for processing the data in the manner of the calculation and compare it to work by a certain time rhythm. Called the Clock signal when they beat once, it will happen once we get activity unit used to measure the speed of the CPU "hoet" (Herzt) It means how many times working on CPU Pentium4 1 sec, for example, there is a 2.5 GHz speed means faster work 2,500 million times. In one second. If the Clock speed, the signal to the computer. There is high speed and the CPU that runs very fast, very affordable prices will rise accordingly.1.3 storage (Storage) which can be split into 2 characteristic function is: 1.3.1 the primary or main storage (Primary Storage or Main Memory) store programs or data that are derived from information to send to central processing units to process and receive the results from processing to export unit provides information which may be split into two types of RAM (Random Access Memory) that can read and write data in the open air, but when it is turned off the data in RAM is lost, and the ROM (Read Only Memory) are read-only, such as the BIOS (Basic Input Output system) ignition apparatus used to bury the computer started, etc. 1.3.2 the backup storage (Secondary Storage) is the unit that serves to store data or programs are entered into the main memory, before processing by the CPU as well as the results from processing. Currently known as the hard disk (Hard disk), or disk (Floppy Disk) year frop, which when turned off, the data is still stored.The unit 1.4 display or output (Output Unit) serves to show the result of the process, including monitor and printer are all 4 sections are connected by bus (Bus)
