Computer Full Form

The term "COMMON Operating Machine" (COMPUTER) refers to equipment used mostly for business, education, and research.

  • C = Common
  • O = Operating
  • M = Machine
  • P = Particularly
  • U = Used
  • T = Trade
  • E = Education
  • R = Research
Computer = Arithmetic Logical Unit + Control unit

Arithmetic (addition, subtraction, division, and multiplication) and logical operations are performed using the ALU, or arithmetic logic unit.
  1. Changes to the order of operations are made in response to information that is stored in the control unit
A general-purpose computer that is created for personal use is known as a personal computer (PC).

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 use 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.

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).
