What is the full form of Computer?

COMPUTER Full Form: Full Form of Computer is “Common Operating Machine Purposely Used for Technological and Educational Research”. This term was created in the mid-20th century when computers were first invented. At first, they were used for scientific and military research, but over time, they became widely used for many purposes. The name 'computer' was given to these machines to show that their main task was calculating and processing large amounts of data.

Computers have become an indispensable part of our everyday lives in the present era. We rely on them for various activities, such as work, entertainment, communication, and education. Though we frequently hear the term 'computer,' have we ever stopped to ponder its true meaning? In this article, we will delve into the full form of the word 'computer' and gain insight into how it operates.

How does a Computer work?

In simple terms, a computer is an electronic device that follows a set of instructions known as software. Its hardware includes various components like the Central Processing Unit (CPU), Random Access Memory (RAM), Hard Disk Drive (HDD), and Input-Output devices. When a user gives a command, the CPU processes it and fetches the necessary data from the RAM or HDD. Finally, the computer displays the result on the screen or through a speaker.

The Function of Computer

The complete term "computer" does not fully capture the device's capabilities. Here are some fundamental tasks that a computer performs beyond calculations and computations:


The input function enables a computer to receive data from the user through input devices like a keyboard, mouse, and so on.

Data Processing: 

Once received through the computer's input devices, the data is subsequently directed to the Central Processing Unit (CPU) for processing. This constitutes the central function of the computer system, with the CPU playing a crucial role. The data introduced into the computer needs to undergo processing, modification, or organization to ultimately yield the intended result for the user interacting with the computer.

Control Unit (CU): 

The control unit of a computer oversees the execution of the input/output memory function and handles any other essential tasks required for data processing.

The Arithmetic Logical Unit (ALU): 

This component is tasked with performing the required mathematical and logical calculations essential for the central processing unit to execute its data processing functions.

Memory Unit (MU): 

The memory unit is accountable for storing, processing, and retrieving the information required for the system's operation, facilitating temporary data storage as well.


After completing the data processing, the data, intended result, or information is displayed to the user through output devices like monitors, printers, and similar tools. The output function represents the final stage of the computer system, primarily aiming to present the user with the system's ultimate outcome.

Advancements in Computing Technology

Computing technology has made remarkable progress since the early days of computers. Initially, computers were large, costly, and had limited capabilities. However, they became smaller, more affordable, and highly efficient as time passed. Computers come in various shapes, such as laptops, desktops, tablets, and smartphones. The computing power of today's machines has seen a significant boost, enabling them to handle complex tasks like Artificial Intelligence and Machine Learning.


The term 'computer' originally aimed to assist with scientific and military research. However, as time passed, computers have become an integral part of our everyday lives, completely transforming how we work, communicate, and learn. Thanks to advancements in computing technology, we can now achieve things that were once considered impossible. The computer's capacity to handle vast amounts of data has become a powerful tool for businesses and individuals. As technology progresses, it's evident that computers will remain crucial in our lives, making everything more convenient, efficient, and productive.
