The CPU specification can be used as the central processing unit of the computer

(CPU) as its heart and brain. Every process executed on the computer must pass through the unit and be processed in it. Therefore, the efficiency of computers is in principle based on simple mathematical operations organized and controlled by the processing unit. Centralization, if we imagine the working principle of a calculator that performs multiple calculations, then its users will enter the numbers and required operations through the keyboard, and then the keyboard enters the data through the binary encryption system (zero and unit), so that The data is transferred to the internal records in p and then the calculator is transferred to the central processing unit.

The central processing unit uses a mathematical logic system to process data. The mathematical logic system is represented by a mathematical logic unit (ALU), where the mathematical logic unit is responsible for all mathematical operations. In the most important tasks of the CPU, we mention the following: Information: As we all know, all instructions are stored in memory and have their own address for access. The processor obtains this address from the so-called program counter and is responsible for tracking instructions that the processing unit should execute in the future.

Decoding and encoding: All programs to be executed are translated into disjointed instructions, and then these instructions are decoded into binary language (zero and unit), which is the main language that the CPU can understand. Execution operation: During the execution of instructions by the CPU, one of the three operations that the CPU can perform is (using arithmetic logic units to perform calculations, transfer data from a specific location in memory to another location, and then move to another address) . Storage: One of the tasks performed by the CPU is to provide feedback after the task is executed, and write the results to memory.

Internal installation of the computer If we have the opportunity to look at the computer from the inside, we will notice the complexity of installing small components from the computer, but the basic components seem to be simpler because we will mention them below: Motherboard: it is mainly in the computer circuit Motherboard power. CPU: A unit installed in the computer box on the motherboard, called the computer brain. RAM: This is the short-term memory of the computer, which is used to store specific data for a short time before it is needed. Hard disk: In addition to documents and other files, it also stores the operating system. This is a long-term memory. power supply device: It is the unit responsible for converting the electrical energy obtained from the household power supply into electrical energy that the computer needs to transmit to the motherboard and the remaining computer components through cables. Identification card: such as sound identification card, video identification card, Internet and other accessories.
