Computer Full Form and Related Full Forms, Abbreviations

The term Computer has no full form which means it is not considered as an acronym. This word is taken from a Latin word ‘computare’ meaning “to sum up”, “to count” or “to calculate”. So, we can see that, it is has some meaning of its own and is nothing but a word.

We have heard many hypothetical full forms regarding computer. The most popular full form of Computer which is used in many purpose is Common Operating Machine Purposely Used for Technological and Education Research’. This full form has no proper meaning for which it is used.

Computer Full Form

Computer, an electronic device, calculations are done using this machine without wasting much time. This was the main purpose at the initial time of invention as calculation required lots of space.

In the recent scenario, we can perform logical and arithmetic functions in the computer which perform operations as per the given instructions. The works performed by a computer is totally correct.

The father of computer, Charles Babbage, plans to develop an analytical engine and in the coming times, it is popular as the computer.

Types of Computer

As per the capability of handling data, computer can be classified into three types such as Analogue Computer, Digital Computer, Hybrid Computer.

Analogue Computer: This type of computers is designed in such as a way that process the analogue data. Data changes frequently within a fixed given values.

Digital Computer: The design of digital computer is such that are able to calculate and logical operations in just few seconds.

Hybrid Computer: As the name indicate, it is a combination of analogue and digital computer. It can perform very fast like analogue computer and, memory and accuracy is similar to the digital computer.

Generation of Computer

Generation of computers indicates the improvement of computer technology over time. Electronic Circuits were introduced used to perform operation like counting in 1946. Instead of Mechanical parts which were used in the previous system, electronic circuit pathways were developed.

First Generation Computer

In the computers of first generation, the CPU and memory mainly consists of vacuum tubes which were very expensive, slow and huge in size. Batch operating system and punch cards were the basic foundation of this type of computers.

Some familiar first generation computers are ENIAC (Electronic Numerical Integrator and Computer), EDVAC (Electronic Discrete Variable Automatic Computer), UNIVACI (Universal Automatic Computer), IBM-701, IBM-650.

Second Generation Computer

Transistors were used in the second generation computers which is compact, cheap and require very less power. It performs operation faster than the previous generation i.e. first generation.

To process program and various operations, there are some assembly and program languages are used such as COBOL and FORTRAN, in the second generation computers.

Some familiar second generation computers are IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108.

Third Generation Computer

Integrated circuits (ICs) replaced the transistors in the third generation computers. The power of computer was increased with less cost. This time computer is more advanced having reliability, efficiency and the size is also decreased.

COBOL, ALGOL-68, FORTRON-II TO IV are some high-level program languages were used in the computers of third generation.

Example of some computer of this series are IBM-360 series, Honeywell-6000 series, PDP (Personal Data Processor), IBM-370/168, TDC-316.

Fourth Generation Computer

Very large scale integrated (VLSI) circuits was the main feature of the fourth generation computers. A chip made up of millions of transistors and other required elements.

Computers of this generation are fur more modified with more compact, fast, powerful and affordable. Some more developed languages such as DBASE, C, C++ become more popular and used in the fourth generation computers.

Some of the fourth generation computers are DEC 10, STAR 1000, PDP 11, CRAY-1(Super Computer), CRAY-X-MP (Super Computer).

Fifth Generation Computer

ULSI (Ultra Large Scale Integration) was used instead of VLSI technology in the fifth generation computers. During this time microprocessor chips were made using electronic components of approximately ten million. Programing languages like Java, .net, C++, C were used in the fifth generation computers.

Some popular types of the fifth generation computers are Desktop, Laptop, Notebook, Ultrabook, Chromebook.

Different Parts of Computer

There are many parts which is in combination makes a computer and is classified as software and hardware.


Hardware parts of a computer is defined as the physical part of the computer. Some of the hardware parts of a computer are mouse, keyboard, monitor etc.

We will briefly discuss about the different hardware parts of a computer.


This is the essential part of a computer and all the processor of a computer is attached to the it. All the ports that are used for connection both output as well as input devices are situated near motherboard.


CPU is popularly known as the brain of the computer. Its main operation is to process the data and provide us the results.


The full form of RAM is Random Access Memory. It is responsible to save all the activities we perform on the computer but erased when we close it.

Hard Drive

All the essential information is saved to the hard drive we used in the computer. Other than this, all the software we install in the computer is saved in the hard drive.

Software Used in Computer

Software is a system of instructions that inform a computer how to operate. To perform various essential tasks in computer we must install software. The main and important software is the OS or Operating System of the computer.

The most popular operating system is Microsoft windows, otherwise iOS, Linux and Ubuntu are also famous.

For different purpose, various types of software are used. Some of the popular software are MS PowerPoint, MS Office, Photoshop, etc.

Advantage of Computer

We cannot imagine our life without computer and influenced our daily life in large extent. Some of the advantage of computer are:

  • We are able to perform multiple tasks at a certain time and thousands of instructions are followed by computers.
  • Accuracy of performance by a computer is very high and it follows the instruction that are given to it.
  • Another advantage of computer is its speed. Modern version of computer can do lots of things within very sort moment.
