Computer Composition and function

Computer composition and function computer composition function 1. Computer composition

计算机的包含5个部分：运算器、控制器、内存、输入、输出   

• An operator: a unit of arithmetic budgeting and logic operations that is essentially an operator of a computer. All computer operations are converted to logical or arithmetic operations or logical + arithmetic operations. For example, you inadvertently on the computer screen, the last CPU will turn this action may be converted to a number of logic + arithmetic operations. In order to complete the arithmetic budget and logical operation, the CPU also designed a register to cooperate with the operation.

• Controller: The command system that dispatches the memory and the orderly operation of the arithmetic.

• Memory: Storage command and instruction space, CPU layer has cache, followed by rate of memory, Pc-eflash, hard disk and so on. The Controller will dispatch the most frequently used instructions or data in the CPU cache, followed by a program run in memory space to complete the operation,
  The results are written on lower-speed disks in a generic program or before the program terminates.

• Input and output: This is actually the interface between human and computer interaction, the early computer input and output mode is perforated tape, with the development of computer technology, we input devices including mouse, keyboard, tablet, drawing board and so on. At the same time on the output, there are displays, printers, tape drives, CD-ROM printers and so on and so on.
