Central processing unit (CPU Central Processing Unit:)Central processing unit, or CPU Also called processor (Processor) or chip (chip) counts as the most important of the hardware because it is responsible for processing user input through an input device based on a set of instructions or programs that the user wants to use. Central processing unit is composed of three major parts, the part is.1. the logical unit (ALU Arithmetic & Logical Unit:) Logical unit functions as a calculator in the computer by the work associated with the mathematical calculations such as addition, subtract, multiply, divide and logical unit of a computer. I still have another one there is no ordinary calculator capable of logical science terms means the ability to compare the mathematical rules and conditions in order to get the answer that that condition is true or false, such as comparing more than, less than equal. 2. no count that this comparison is often used to select a computer to follow the commands of a program is the next command.2. the control unit (Control Unit). The control unit that the procedure bakhum, processing and operation of devices within the central processing unit and include the coordination of work between the central processing unit to import device information display, and memory backup. If you want to process by which set of commands. The user will be required to submit their data, and a set of instructions to log on to the computer. By the above set of commands and data to be stored in main memory first. Then the control unit commands from the commands that are available in the main memory came out one at a time to do the translation. Means that command, which works with the hardware information. When you know the meaning of the command and control unit, it will be sent. The command signal to the hard ware Best acting in processing them, follow them, for example, if the command that added the command about the calculations. The control unit will send the signal. Command to logical unit to work. A logical unit, is to pull the data from main memory into the order processing and the result to display the device display. Fixed units before transmitting bakhum command to the device displays the result set to retrieve data from the main memory out to demonstrate such results. The other one3. main memory (Main Memory) It can work when there is a set of instructions and data that are processed in the main memory only, and already after processing the information according to the routine equipments. The result will be taken to the main memory, and the first to be brought out to show that the device display.• Operation of the computer. Using the archive command to memory The CPU reads instructions from memory, come to interpret and perform according to each word. The main duties of the order, the CPU is the control of computer systems, as well as the processing.• The working mechanisms of the CPU There is a complex. The developer has already created mechanisms for the CPU to work. The work is divided into sections with parallel work and staggered to work faster.
