Understanding CPU, Components and How It Works

Thursday, March 16th 2017. | Software

CPU (Central Processing Unit) is the brain of the computer system which is a tool of the processing center. CPU is also often referred to as the processor. Fungsi excel although often encountered in any of our daily activities, but still many people who do not know how it works and how important CPU in a computer. To answer that, the information presented below will discuss about Understanding CPU, the CPU component and how the CPU.

As already mentioned briefly earlier, the following we will present more detailed information regarding the definition of the CPU. The CPU is the computer hardware that is tasked to implement the orders of the computer software . The CPU is the main component of a computer that acts as the brain of the computer system. You could say almost all computer operations executed by the CPU.

Understanding CPU, Components and How It Works

After knowing the definition of CPU, then we will discuss about CPU components. Here are some components in the CPU, namely:

1. Unit control
unit control is the component that governs the course of the program. Unit control are important components that exist in the CPU. The control unit tasked to synchronize between components in the CPU, so the CPU can execute operations function properly. In addition the control unit is also responsible for taking only instructions from main memory and determine the type of the instruction. In general, the control unit on duty to control or regulate the input and output, retrieve data from main memory and stores it in the main memory.

2. Register
Register is a component that is used to store instructions or data being processed. This storage is only temporary because typically registers only used to store data when it is processed.

3. ALU
ALU is a component that is used to perform arithmetic operations or logic operations. ALU is often referred to as machine language. Besides ALU also served to make decisions in accordance with the instructions associated with the program logic operations.

4. Interconnections CPU
CPU Interconnections is the component that connects the various internal components such as the CPU ALU, control unit and registers with the external CPU bus and also serves to connect with other systems.

How it Works CPU

After learning about Understanding CPU and its components, the next is to discuss about how the CPU. Although referred to as the “brains” of the computer, but the CPU does not really work like a human. CPU only works for moving data that has been determined by the program.

Basically the CPU works with three basic functions, which receives inputs (input), process the data and provide output (output). Input is an external process of entering data into the computer. Which includes an input device on a computer is the mouse, keyboard, modem and scanner. Once the input data will then be processed into output by the CPU. The output is the result of data processing performed by the computer system.

The output can be stored permanently or temporarily. Here, the role of memory. If the instruction is given in the form of logic and arithmetic, the ALU will take over the operations and then process them. If the instruction has been completed, the control unit will take the results of the processing that previously had been housed or stored temporarily to be accommodated again to Output-Storage.

Having accommodated in the Output-Storage, the next result of the processing of the system will be displayed in the Output Device, through the devices installed on the computer such as a monitor, printer or computer programs that run.

That information regarding the definition of CPU components found in it, as well as how the CPU may be useful for all readers.
