Full Form of Computer and Related Full Forms, Abbreviations

Hello Dear Aspirants,

Full Form of Computer: A computer is an electronic machine that accepts data from the user, processes the data by performing calculations and operations on it and generates the desired outcome or result. The computer is derived from the Latin word ‘computerae’ which means ‘to compute’. The full form of the Computer is Common Operating Machine Purposely Used for Technological and Educational Research.

What is the full form of Computer?

The full form of computer is given below:

• C = Common
• O = Operating
• M = Machine
• P = Particularly
• U = Used
• T = Trade
• E = Education
• R = Research

The full form of a Computer is a “Common Operating Machine Purposely Used for Technological and Educational Research”. The term was coined in the mid-20th century when computers were first developed. Initially, computers were used for scientific and military research, but with time, their usage became widespread. The name ‘computer’ was given to these machines to indicate their purpose, which was to compute and process large amounts of data.

Computer = Arithmetic Logical Unit + Control unit

ALU: Arithmetic Logical Unit is used to carry out arithmetic (addition, subtraction, division, and multiplication) and logical operation.

CU: Control unit is used to change the order of operations in response to stored information 

How does a computer work?

A computer is an electronic device that operates on a set of instructions called software. The computer hardware comprises several components, including the Central Processing Unit (CPU), Random Access Memory (RAM), Hard Disk Drive (HDD), and Input-Output devices. When a user gives an instruction, the CPU processes it and retrieves the required data from the RAM or HDD. The output is then displayed on the screen or through a speaker.

Advancements in Computing Technology

Since the inception of computers, computing technology has advanced tremendously. The first computers were massive and expensive, and they had limited capabilities. However, with time, computers have become more compact, affordable, and efficient. Today, we have computers in various forms, including laptops, desktops, tablets, and smartphones. The computing power of modern-day computers has increased significantly, making it possible to perform complex tasks such as Artificial Intelligence and Machine Learning.

What types of computers are there?

The way a computer performs particular activities can be used to classify it. The following are the basic categories:

1. Digital Computer
2. Analog Computer
3. Hybrid Computer

Generations of Computer

First-generation computer :

These computers were large and expensive and required specialized technicians to operate and maintain them. They were primarily used for military and scientific applications, such as calculating artillery firing tables and performing atomic energy calculations.

The first generation of computers was characterized by their use of vacuum tubes and their reliance on punched cards for input and output. They were also relatively slow, with processing speeds measured in milliseconds. Despite their limitations, the first generation of computers laid the foundation for the development of modern computers and revolutionized the way we process and store information.

Second-generation of computer

The main characteristics of second-generation computers were:

Use of transistors: The use of transistors in second-generation computers made them faster, more reliable, and more energy efficient than first-generation computers, which used vacuum tubes.

Magnetic storage: Second-generation computers used magnetic storage devices such as magnetic disks and tapes to store data. These devices could store large amounts of data and were more reliable than the punched card storage used in first-generation computers.

Ferrite core memory: Ferrite core memory was used as the main memory in second-generation computers. It was faster and more reliable than the magnetic drums used in first-generation computers.

Formal languages: Second-generation computers used formal languages such as COBOL and FORTRAN for programming, which made it easier for programmers to write code.

Time-sharing: Second-generation computers introduced the concept of time-sharing, which allowed multiple users to access the computer at the same time. This made it possible for computer users to work on the same computer simultaneously, increasing productivity.

Overall, second-generation computers were a significant improvement over first-generation computers and laid the foundation for the development of modern computers.

Third-generation of computer

The third generation covers the years 1964 to 1977. In its place, transistors were replaced by integrated circuit (IC) chips. Transistors, registers, and capacitors can all be found in large quantities on a single Integrated Circuit (IC) chip. 

IBM-360 and VAX-750 are two examples of third-generation computers.

Fourth-generation of computer

The fourth generation spans the years 1978 through 1990. VLSI was used in the fourth generation. VLSI, in its full definition, is an extremely large-scale integration. VLSI refers to an integrated circuit chip with more than 1000 embedded components. This generation produced personal computers. 

Apple and IBM both offer fourth-generation products as examples.

Fifth-generation of computer

The fifth generation spans the years 1991 to the present. Uncertain ULSI chips were introduced in the fifth generation. Ultra Large Scale Integration is the full name for this technology. New technologies are introduced in the fifth generation, such as machine learning and artificial intelligence (AI).
