Computers have become one of the most important things we need in our lives, especially in this time of the pandemic when everything turned online from classes to payments to board meetings and everything else. When computers are so important to us should we not know more about them? So we have brought you information about the different components of computer.
This Blog Includes:
First of all, we should know what computers are to know more about them. A computer is a machine that is made up of various parts or components which help it in carrying out instructions which are in the form of arithmetic commands or different algorithms for it to process. Computers are used in almost every field like medicine, travel, education, entertainment, etc. It has made our work way easier than ever before.
Components of Computer
The main things that comprise a computer are – motherboard, CPU, GPU, RAM and Hard disk drive for the storage of all the data. We will discuss all these components of the computer in detail below:
A motherboard is a circuit board through which all the different components of a computer communications and it keeps everything together. The input and output devices are plugged into the motherboard for function.
Computers respond to commands given to them in the form of numbers, alphabets, images etc. through input units or devices like – keyboard, joystick etc. These inputs are then processed and converted to computer language and then the response is the output in the language that we understand or the one we have programmed the computer with.
The result of the command we provide the computer with through the input device is called the output. The most used is the monitor since we give commands using the keyboard and after the processing, the result or outcome is displayed on the monitor.
Central Processing Unit (CPU)
The CPU is called the brain of the computer since no action can take place without its permission and execution as the main processing unit. It communicates with all the other components of the computer and has 3 components that help in the smooth functioning of the CPU. Components of the CPU are:
The information entered through the input devices is saved in the memory of the CPU and then passed on to the other parts. Similarly, when the output is ready it is saved in the memory before the result is given to the user.
This unit controls the functioning component of the computer. It collects the data entered, leads it on for processing after the processing is done, receives the output and provides it to the user. So getting instructions, decoding it, signalling the execution and receiving the output is done by the control centre and hence it is called the centre of all processing actions that happen in the computer.
Arithmetic and Logical Unit
This unit does mathematical calculations, arithmetic operations, comparison of data and decision making. It has circuits that are built for addition, subtraction, multiplication, division and other calculations.
Graphics Processing Unit (GPU)
Another vital component of the computer is GPU. The Graphics Processing Unit or the video card helps generate high-end visuals like the ones in video games. Good graphics like these are also helpful for people who have to execute their work through images like 3D modellers and others who use resource-intensive software. It generally communicates directly with the monitor.
Random Access Memory (RAM)
RAM is the most commonly referred component in a computer. The RAM is also known as the volatile memory since it gets erased every time the computer restarts. It stores the data regarding the programs which are frequently accessed programs and processes. It helps programs to start up and close quickly. It being slower has made it more obsolete these days.
The computers need to store all their data and they have either a Hard Disk Drive (HDD) or a Solid State Drive (SDD) for this purpose. Hard disk drives are disks that store data and this data is read by a mechanical arm. Solid-State drives are like SIM cards in mobile phones. They have no moving parts and are faster than hard drives. There is no need for a mechanical arm to find data on a physical location on the drive and therefore this takes no time at all.
