Components Of A Computer: Five Essential Ones


Components Of Computer: Five Essential Ones

Introduction

Are you about to start your journey in the world of computing? Then, you must know about the major components of a computer, to be able to handle it with ease. However, the internal architecture varies from one variation to another. Nonetheless, the basic concept remains the same. Without further ado, lets begin.

Input Unit: One Of The Key Components Of A Computer

If you want an output from your computer, it must be fed with an input. You can give the input in the form of data as well as instructions. However, the input unit of a computer connects the device with the external environment.

Nonetheless, input units collect inputs in forms, which depends on the respective input device. For instance, the input signals received from a keyboard and a mouse would be different.

Output Unit: Among The Crucial Key Components Of A Computer

An output unit is the opposite of an input unit. Once the processing is done, results are displayed by the output unit. That is how an output unit also links the system to the outside world. You might be aware that computers work with binary numbers (0 & 1). The output produced is also in binary form.

However, human beings are not well-accustomed with the strings of 0’s and 1’s. Hence, the output converts into human-readable form before displaying it to the external environment. All credit goes to units, known as output interfaces.

Storage Unit

Storage is an important aspect before processing comes to action. Storing information is also essential before displaying the output to the outside world. Hence, some space must be there, where data and information can be saved.

Two kinds of storage devices are there in a computer. One is a primary storage device (RAM or Random Access Memory), and the next one is a secondary storage device. The latter can either be internal or external and is removable by nature.

Central Processing Unit (CPU):

It is not possible to imagine a computer system without a CPU. It takes care of every activity inside the system. Moreover, it also holds direct control over internal as well as external devices. A CPU also executes arithmetic and logical operations through the ALU. Moreover, a microprocessor of the CPU executes “instruction set” which is then “hard wired” in the processor. It then decides the machine language for the Central Processing Unit.

Control Unit:

A Control unit is a key segment of a computer. As the name suggests, it controls the operations inside the system. It selects, interprets, and observes the program instructions’ execution process.

Wrapping Up

I hope you learnt about the key components of the computer. You can now handle your device with ease. Moreover, you can also start learning about its more advance levels. A computer is a wonder in itself and knowing about is such a privilege, is not it?
