The processor plays a crucial role in determining the speed, efficiency, and overall performance of your Computer system. So understanding what is processor and how it works can give you deeper insight into how your devices operate and why they perform the way they do.

In this article, we’ll explore the basics of processors and their functions.

What is processor, exactly?

A processor is an integrated electronic circuit that performs the calculations that run a computer, such as arithmetic, input/output, logical and other basic instructions. CPU stands for central processing unit, another name for the processor. Besides, micro-processes are commonly linked as synonyms.

However, nowadays, most people use the word processor interchangeably with the term CPU. However, since the central processing unit is only one of a personal computer's processors, it is technically incorrect.

In addition, the CPU is not the only processor in a computer; there are many other processors available. One of the most notable examples is the graphics processing unit (GPU). The hard drive and other devices with a computer also perform some processing independently.

What is the processor in a computer?

The processor in a computer works like a brain. It performs program tasks, calculates data from input and manages other parts like memory, what shows up on the screen and devices connected to the computer.

What do processors do?

Usually, processors handle all the complex calculations and operations that make your computer run programs perform various tasks and open files. In addition, the process uses data and instructions from games, applications and other software.

How does the processor work?

Every processor is made up of one or more individual processing units, which are called cores. Each core processes instructions from a single computing task at a particular speed, which is also known as clock speed. Measuring this speed through GHZ. Within the processor, there are four main key elements, including an arithmetic logic unit, a floating point unit, registers and cache memories.

ALU elements carry basic and advanced arithmetic and logic operations. Resulting sent to registers, which are also store instructions. However, to process instructions, processors use an instruction pipeline that involves stages such as fetch, decode, execute and write back.

Different Types of Processors

There are three most common types of processors are there. Each type is designed for different purposes and performance levels. Some are made for basic tasks such as writing documents, surfing the web, and browsing, while others are more powerful and can handle demanding tasks such as video editing or gaming. Below we discuss these types, such as:

Single Core Processors

Single-core processors are the oldest type of computer CPUs, which were used in the 1970s. Usually, it has only a single core which performs different operations which means the single-core CPU can only process one operation at a single time. As a result, it is not suitable for multitasking.

Dual-core processors

These CPUs contain a single integrated circuit with two cores and each has its cache and controller. These dual-core CPUs function as a single unit with the controllers and cache. In addition, it can work faster than single-core processors.

Quad-core processors

This quad-core control processing unit contains two dual-core processors that are present within a single integrated circuit. A quad-core processor, on the other hand, has four cores on the chip that read and process different kinds of instructions.
