Central Processing Unit (CPU): Definition, Uses and Function

If you are naive to the world of computers and electronics, the terminology used to designate the different parts can lead to confusion in navigation. A component expression you may have encountered is “CPU”.

The CPU is the basic unit for almost all the devices it owns.

The CPUs or Central Processing Units are responsible for processing and executing instructions. Read on to find out how CPUs interact with other parts of your devices and what makes them so integrated into the IT process.

What makes a CPU?

The CPU is a primary component of defining a computing device, but it is not the only component; again, these are just brains. It is a chip that is located in a special seat (socket) located on the mainboard (motherboard) inside the device.

It is separated from memory, where it temporarily stores information. It is also independent of the graphics card or graphics chip, displaying all the videos and 3D graphics on the screen.

CPUs are assembled by placing billions of microscopic transistors on a single computer chip. These transistors provide you with the calculations you need to run programs stored in your system memory.

Indeed, these tiny doors activate or deactivate, transmitting those or zeros that transform into everything you do with the device, whether you watch videos or write emails.

One of the most common advances in CPU technology is to make these transistors smaller and smaller. As a result, processor speed, often known as Moore’s Law, has improved over the decades.

With modern devices, a desktop or laptop computer has a dedicated processor that performs many processing functions in the system.


Mobile devices and some tablets use the system on chip (SoC), which is the chip that contains your processor and other components.

Intel and AMD offer a processor with graphics chips and memory stored, which means that they can perform more than standard processor functions.

What does the CPU do?

Central Processing Unit (CPU)

The CPU takes instructions from a program or application and performs a calculation. This process is divided into three key phases: recovery, decoding, and execution. The CPU receives instructions from RAM, decodes it, then executes it using the relevant parts of the CPU.

An instruction or a calculation executed can involve basic arithmetic, the comparison of specific numbers between them, or their displacement in memory.

Since numbers represent everything on a computer device, these simple tasks are the same as what a processor does. This makes everything easier, from starting Windows to playing YouTube videos.

In modern systems, the processor is not everything, but it has to supply specialized hardware with the numbers it needs to operate.

You should tell the graphics card to display an explosion because it clicked on the (huge) fuel tank or an announcement on the hard drive to transfer the Office document to the system RAM for faster access.

Core, Watches, and Costs

Initially, the processors had only one processing core. Today’s modern processor is made up of multiple cores that allow you to execute various instructions simultaneously, effectively bundling numerous processors on a single chip.

Almost all processors sold today are at least dual-core, but at the top, you will see four (four) processors and up to six, eight, 10, 12, and 16 cores in some cases.

Some processors also use a technology called multiple guidance. Imagine a single physical processor core that can execute two execution lines (threads) at a time, appearing as two “logical” cores at the end of the operating system.


These virtual cores are not as strong as the physical cores, but they share the same resources. In general, they can improve the performance of multiple CPU tasks by running compatible software.

Another huge number of CPUs is clock speed – the “gigahertz” (GHz) number listed in the product lists. It does indicate the number of instructions the processor can process per second, but that’s not all in terms of performance.

The clock speed is mainly taken into account when comparing processors of the same family or generation of products. When everything else is the same, a higher clock speed means a faster processor, but a 3GHz processor in 2010 will not be as fast as a 2GHz processor in 2018.

So how much should you pay for a processor? We have a few guides that will give you some suggestions on the best processors you can buy.

However, for the general scheme, unless you are a picky gamer or someone who wants to edit photos or videos, you don’t need to spend more than $200. Join the latest generation.

For Intel processors, this means eighth, ninth, or tenth generation chips. You can determine its production by the name of the product.

The Core i7-6820HK is an older sixth-generation chip, while the Core i5-10210U is a newer tenth generation chip. AMD does something similar with its Ryzen processors: the Ryzen 5 2500X is a second-generation chip based on a new basic “Zen” design, while the Ryzen 9 3950X is a third-generation processor.

We have bolded the indicator numbers so that you can see them in the future.

How Important is the CPU?

Although the CPU is not as necessary for overall system performance, it still plays an essential role in boosting the device. Since you are solely responsible for executing commands in the program, the faster your processor, the quicker the applications run.

That said, a fast processor isn’t everything. The processor, whatever its power, cannot easily play the latest 3D games or store information. Other components, like graphics cards and memory, are also played there.


In short, the CPU is not everything, but it is vital. In general, a faster processor means that your system or device will boot faster. At the very least, it will not be a bottleneck in itself. Several hearts and threads can help you do several things at once.
