What is a CPU? Meaning, Definition, and What CPU Stands For

What is a CPUs

CPU stands for Central Processing Unit, which translates into Spanish as the central processing unit for an electronic device, such as a computer, mobile phone, tablet, video game console, etc. A CPU is a board or chip that integrates into a Motherboard and contains all the necessary circuits for the operation of an electronic device.

The job of the CPU is to perform all the logical and mathematical tasks that the device requires so that it can perform the tasks required by the user.

Computers can have more than one CPU, such as multi-core processors that connect two CPUs to one chip. This is also the case with formatted computers, which incorporate multiple CPUs to accelerate information processing power.

Size Of CPU:

The size of the CPU is much smaller than previous models, which is why it is also called a microprocessor.It is a mistake to use the acronym CPU to refer to a desktop computer tower, case or case. The tower is not the central processing unit but the place where all the important components including your motherboard and CPU are located.

Who is the CPU for?

The central processing unit is used to “read” and follow instructions for programs installed on a computer, telephone, or other electronic device.

This process is done in four stages:

Search:The CPU searches for RAM for the data it needs to follow instructions.

Decoding: Data analysis is done to understand what the instructions are about.

Implementation: The decoding instructions are followed. This is when the program “runs”.

Write: The search process does the opposite. Data is reloaded, but this time from CPU to memory.

What are the components of the CPU?

A central processing unit consists of:

Control Unit: This is the part of the CPU that searches for instructions in the device’s main memory, interprets the data and sends it to the processing unit for execution.

Processing Unit: Here the instructions received from the control unit are executed by the Mathematical Logic Unit (ALU) which performs basic operations such as addition, subtraction, multiplication, logic functions, sign changes etc.

Input and output bus: This is the system in charge of transferring data through all components of the CPU.

Cache Memory: This is the part of the CPU where the most frequently used files are stored by the user, so that they can be accessed quickly.

CPU Features

Regardless of their type, CPUs have several features that determine their performance and functionality:

The number of threads

Threads are program instructions that are responsible for performing multiple tasks simultaneously, preventing computer performance from being affected.

They are often confused with Dana, as they also allow multiple tasks to be performed. However, the threads act as part of the software, while the core is the physical components of the processor.Generally, there are two threads for each cover.

Number of cores

The more cores, the more work the CPU can do and the faster it can do it.

Energy consumption

CPU power consumption is measured in watts (W) and the higher the capacity of the CPU, the higher the power consumption.

Clock frequency

This is a measure of CPU power and is measured in Mhz or Ghz. It is divided into two types:

Base frequency: The minimum power required for a computer to perform basic tasks, such as power on / off, operating system operation, etc.

Turbo frequency: For example, the power required to perform complex processes such as video games.

We are going to tell you exactly what the CPU of a computer is and for whom it is. This is a very complex component, although it is the brain of every computer or device, but we are going to try to make everything as simple as possible so that you can understand the basic concepts of its operation.Much more can be said about the CPU than we are going to tell you, as it is possible to go deeper into the features of its operation. However, what we want here is that if you have never heard of it, you can understand its basic principles so that at least you know what we are talking about.

The CPU is a system of language codes that tell the processor instructions for proper operation of the device.

Processors do not translate any kind of information, but it is written in binary form, with the letters zero and one. Each program or application is made up of a chain of instructions written in this code, which are interpreted correctly by the machine. You ask your photo app to calculate. This application instructs the computer with the calculations or actions it needs to perform in order to perform the task. Instructions are inserted into RAM, where they are picked up by the CPU, which performs them.

To do this, several different steps are followed. The first step is to read the data and instructions for performing each of the applications. Data is decoded and distributed so that it can be understood from different parts of the CPU, which perform actions, make calculations, and write the results in main memory, either as a result or later in other tasks.

But it is very simple, because these basic functions of the processor are performed according to each instruction, and each instruction may require several instructions to execute each program. Also, these are not performed one after the other, but the processor can work with many functions at the same time for different functional programs.

You have to understand that everything in your computer is represented by numbers, so the CPU is in charge of collecting and calculating the operations of these numbers. With these actions, everything you do on your computer is accomplished, from opening the Windows Start menu to watching videos on YouTube, everything requires a series of instructions and calculations to do it. Is.


In modern computers, the CPU is not the one that does everything, as other special components usually interfere, such as the graphics card for everything related to what you see on the screen. RAM memory is also used to store fast-accessing data, and the rest of the components inside your computer.In this multitude of devices and components, the CPU is the brain or conductor, because it is the one that organises everything so that tasks can be performed where they should be and the way in which they can achieve the desired results. Should go .
