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, here we want that if you have never heard of it, you can understand its basic principles so that at least you can know who we are talking about.
What is a CPU?
CPU stands for Central Processing Unit, which translates to Central Processing Unit. This is one of the most important components you will find in your computer, your smartphone or your tablet or laptop, and even in watches and virtually any electronic device. Without it, they just can’t work.
The CPU is often colloquially called a microprocessor or just a processor, and you can think of it as the brain of any device. It is responsible for carrying out all instructions of the device, reading the operating system orders and requirements as well as the instructions for each of the components and applications.
Therefore, like the brain, the CPU is responsible for making sure that everything is working properly, and that the operating system or components want to interpret what they want to do, establish connections and make it work. Is responsible for performing all the necessary calculations. The more powerful the processor, the faster it can operate and in general, your device will work just as fast.
What are the parts of a computer processor?
The central processing unit is made up of various parts, with two of them standing out as the most important:
- Mathematical Logic Unit (ALU): The processor’s functions (mathematics or logic) are named after it. So it’s a decoding engine that gets a code and chooses the appropriate operation to decode it.
- Control Unit: Receives data or instructions into storage, processes them, and then sends them out. It tells where each element should work, therefore it controls the CPU’s inner workings.
The remaining components of the central processor are:
Address Bus: This bus sends addresses to ram and devices in order to determine wherever data is stored or read.
Databus: This allows the CPU to send and receive data from peripherals and memory.
The Instruction Register keeps track of the instructions that are executed at any given time.
Data is briefly stored in a log file.
The next instructions have a memory address that must be followed.
The next memory location from which data will be read or written is stored in the Memory Address Index.
Because processors are digital circuit systems, the clock indicates the signal upon which CPU functions.
What is the function of the CPU?
The CPU operates in four simple steps: read, decode, execute, and write, all of which are performed using a binary language based on 0s and 1s. The central processor is in charge of reading data in the initial stage, which will be arranged subsequently. At this stage, there is no similarity because the amount of data read is smaller than what can be processed, hence caching and multi-channel are essential.
The received data is next evaluated in accordance with the instructions in order to be decrypted. The received data is processed at the end of this phase to finish the final recorded phase, in which the microprocessor is in charge of sending the findings to the computer’s memory.
How is the CPU?
The CPU is usually small, square in shape, and has metal connectors and pins. It is usually installed in a special socket on the computer’s motherboard, which can be in different places depending on the motherboard. The processor is not soldered to the board, so you can change the CPU of one computer to another if you wish.
Inside the CPU is at least one processor or core, a chip for calculation and operation. Initially they all had only one, but over time the CPUs are increasing the number of these cores, and there are different ways to call them depending on the number.
For example, if you’ve ever heard of a dual-core processor, it’s because it has two of those chips inside. Then they evolved into four, quad-core, and growing to six, eight or even 12-core or more. They are all identified by the name which contains the word core, but before that the number of cores is referred to.
The fact that a CPU has multiple processors or cores usually means that it is capable of performing multiple operations at the same time, so its operation can be faster and better. However, this does not always mean that the more cores there are, the faster everything will be, because it is something that also depends on how each cover is.
For example, some processors from two major manufacturers, Intel and AMD, have technologies that allow them to execute two threads in a single core, a set of operating system or application instructions. Implementation threads, or threads in English, are related to instructions related to the operating system or application.
Who is the CPU for?
Your computer’s CPU is the one that follows the instructions and processes its data. These instructions are programs that you have installed on your computer. Come on, they are responsible for doing the things that programs or applications need you to do.
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. For use in
The CPU is no more important than the other basic components of a computer, as the computer will not function without a power supply or other components. Nor is it something that the completion of tasks depends on, because everything related to the production of videos or the concept of video games requires a good graphics card or GPU and good RAM.
But the speed and power of the CPU can depend on how fast the computer is moving, and whether the CPU is good or bad will affect the performance of your computer.
