Technology has been growing in recent years and thanks to it, many things have been created, which aim to make people’s lives easier. Among the things that have appeared as a result of technology, we can mention the CPU (for its acronym in English  Central Processing Unit , which translated into Spanish would be central processing unit ), which can be considered as the brain of the computer, Because it is used to perform all binary code calculations, process all the activities requested by the user, read all open programs and also allows the computer itself to function correctly (since sometimes it also regulates the electricity that is sent to each part of the computer)

What is the CPU for?

Since the advent of CPUs in 1969 (the year Intel released the first version of a CPU), they have been essential for the proper functioning of most, if not all, computers. The use of CPUs is mainly due to the fact that it provides a large number of benefits, among which the following can be mentioned:

Allows you to read and open programs

When a person downloads a program, its information is stored on the hard disk, however, when it is stored in it, it is in the form of binary numbers, that is; a large sequence of numbers that can only be translated by electronic components with a high processing capacity.

Now, once the computer user decides to open a program, what really happens is that an order is given to the hard disk to send the information of the program (which is in binary numbers), to the CPU (although first goes through the RAM, since this is the one that is responsible for sending information from one side to the other). Once it reaches the CPU, it is in charge of reading and translating the information, to later proceed to send different data to the RAM memory, once this data arrives here, it is in charge of sending it to other parts of the computer, to allow the correct reading and execution of the program that has been requested to open.

It is important to note that all this happens in a matter of microseconds and the amount of numbers that the CPU can process is really incredible, although this may vary depending on the capabilities of the same.

It allows to improve the performance with which the programs are opened

Inside the CPU there is something called cache memory, this memory is basically in charge of saving the programs that are being executed. Thanks to this memory, when a program is minimized to open another and later the minimized program is reopened, it continues to function normally, that is; It is not necessary to wait for it to start again, since the data of said program has been stored in the cache memory, allowing that when the user of a computer reopens a minimized program, the CPU can resume the activities in where he had left them.

This makes using the computer faster and more enjoyable, since you don’t have to wait for the program to start every time it is minimized. It is important to note that, depending on the cache memory, there will be a certain capacity to minimize programs and reopen them without having to wait for them to start again from scratch.

Thanks to the CPU, the operating system can work

It is important to understand that an operating system can be defined as a set of programs that allow easy use of a computer. In other words, thanks to the operating system, it is not necessary to have to write codes to be able to open a program and use the computer.

Thanks to the CPU, it can be said that the operating system works, since it is this one who is in charge of executing all the parts of it, allowing it to work correctly. Also, depending on the capabilities of the CPU, it can make the operating system run much faster.

How does the CPU work?

Perhaps it can be thought that understanding the operation of the CPU can be a complicated task, however, it is relatively simple, because it has to be taken into account that there is an input and an output (there may be more inputs and outputs, depending on the the processing capacity that the CPU has. If the information processed per second is very high, it tends to have more than one output and one input). Now, when a program is opened (an order is given to the hard disk), it is in charge of sending certain information to the CPU, once it receives the information, it is in charge of carrying out the following activities:

  • Collect, organize and detect how the information should be processed . At this point it is important to note that most programs (if not all) have a kind of guide, which is in the first place. This guide (so to call it), allows the processor to know how to process the algorithms.
  • Divide the information . Once you know how it should be read, proceed to divide it, to make it easier to read.
  • Execute the information . In this part, the CPU is in charge of solving all the algorithms, to understand what should be shown to the user of a computer; basically, it is in charge of translating the numbers into a numerical language understandable to all parts of the computer.
  • Submit the information . Once it knows what to do, it sends the information to RAM, so that it is in charge of sending it to other parts of the computer, which causes them to start executing part of the solved algorithms and therefore , the execution of a certain program can be given.

It is important to mention that these operations can be done at the same time inside the CPU, that is to say; While one part of the CPU is dividing certain information, another is gathering and organizing other tasks requested by the computer user. Also, this whole process does not take a second, although this may vary depending on the capabilities of the CPU, as mentioned above.

Finally, these processes are done constantly, until the program is closed. That is to say; While the user is carrying out any activity with the program or the user is doing something with the computer, the CPU will continue executing the algorithms, to know what changes there must be for the correct operation of the program.

What is the main function of the CPU?

The main function of the CPU is to solve the algorithms presented by the programs stored on a hard disk. In addition, it allows to know what operations each part of the computer must execute, so that later the RAM memory can be in charge of sending said information to the corresponding parts and therefore, allow the correct operation of a certain program (or set of them).

Relevant aspects of the CPU

If you want to know more about the CPU, it is important to take into account some relevant aspects, because it is a fairly broad topic. Among the aspects to be considered are the following:

CPU price

The price of the CPU is very relative, because it depends a lot on its capabilities. However, it can be said that its price can vary between 10 and 500 USD, depending on the capacities, the brand, its compatibility, the generation, among other things.

On the other hand, it is important to know that there are people who confuse the CPU with the computer as such and this is a big mistake, therefore, when looking for references on the Internet, care must be taken.

CPU meaning

As explained above, CPU means central processing unit in Spanish and its acronym comes from its English name  Central Processing Unit.

conclusion

The CPU is really one of the most important complements of a computer, therefore, it can be said that it is essential for the correct functioning of the same, this as a result of the activities that it carries out, which allow the computer to execute the programs correctly.

Taking into account that this, it is essential to know how it works and understand how it can be damaged if the computer is not used correctly.
