What is a processor

Devices that we use regularly such as computers, laptops, mobile phones all have processors. So today’s topic is the processor. The word processor is intimately associated with computers or smartphones. Because no smartphone or computer will run without a processor. Therefore, it is important for everyone to have an idea about this important part of the computer.

The processor is the brain of the computer. Just as the human brain works by directing all the organs, so do the processors of computers and smartphones. However, there are some differences between computer processors and smartphone processors. Anyway, today we will discuss about this processor.

What is a processor?

Processor is one of the main hardware of computer. Basically it is called CPU = Central Processing Unit. The microprocessor is literally a self-contained and programmable mathematical engine. Which controls and performs all the operations of the computer through instruction.

In 1981, Intel started marketing a microprocessor called 4004. These processors are made up of thousands of transistors on silicon. Over time, the processor began to evolve. The two most popular processors for computers today are:

And for smartphones-

How does the processor work?

When we choose a processor, the things we should focus on are-

  • CLOCK SPEED
  • NUMBER OF CORES
  • CACHE MEMORY
  • FSB

CLOCK SPEED

Clock speed is also called GHz. It is written on each processor such as-3.00 GHz3.4 GHz4.00 GHz etc. In simple terms, it determines how fast your computer can calculate. That is, the clock speed is used to measure how many calculations a processor can make per second.

CORE

The core is a lot like a human hand. People have two hands, now it will work with these 2 hands, now if it had 4 hands, it will be able to work faster. Similarly, the core of a computer does this job. Although the number of human hands cannot be increased, the number of computer cores can be increased. Usually, 5 types of cores are seen. E.g .:

  • Dual-core – 2 cores
  • Quad Core – 4 cores
  • Hexa core – 6 cores
  • octa core – 8 cores
  • Deca Core – 10 cores

As the core grows you will be able to do many things at once. For example, you can use the Internet effortlessly by turning on music in the music player. But, if there is 1 core, then anyone can be turned off if you turn on the song and use the internet.

CACHE MEMORY

All the work that the computer has to do repeatedly, all the work is stored in this cache memory. As a result of storing the cache in memory, it is faster to do the same thing for the second time. Cache memory is usually up to 8 MB.

FSB

Not all processor data is in cache memory, most data is in RAM. And how fast the processor can communicate with RAM is understood by FSB. However, current processors use QPi instead.32-bit and 64-bit. Earlier we discussed that computers work in binary mode. Where each binary is called a bit. And these bits indicate who can calculate the maximum number of 32-bit and 64-bit together. Normally 64-bit can calculate faster, so it will work faster.

The difference between a computer processor and a mobile processor


Size

If there is a difference between a mobile and a computer processor, the size of the processor will come first. The size of the computer processor is relatively larger than the processor of the mobile. Of course, since the computer processor is more powerful in terms of work, its size is also much larger.

Speed

The speed of a computer processor is much higher than that of a mobile processor. Because there is a separate cooling system for computer processors. In the case of mobile processors, the cooling system of the computer is missing. So, its size is a bit smaller than a computer processor.

Energy consumption


Computer processors are both large in size and capacity. And that’s why computer processors consume more power. If you want more performance, the processor will consume a lot of power. A powerful computer consumes 450 to 650 watts or more of electricity. And it produces a lot of heat, which requires a cooling system. And since mobile phones run on batteries, their processors consume relatively less power. And so there are fewer hits and no separate cooling is required.
SiliconeMobile processors use less silicon. Because less space and size is important for mobile processor. On the other hand, performance is more important than size in computer processor. So, more silicone is used here.

This was a brief discussion of the processor. We have tried to discuss how the processor works in different parts so that you can easily understand. I hope you know something new about the processor.

There was a fascination with technology from a very young age, and perhaps that fascination is a little more than other ordinary people. From Nokia's button phones to infinity display bezel-less smartphones, everything is my favorite. Technology has never been more impressive in my life. And writing started with an interest in this technology .....
