Computer Full Form
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.
| 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
What are the categories of computers?
The computer can be categorized in the form of its way to process certain operations. The basic categories are as follows-
- Digital Computer
- Analog Computer
- Hybrid Computer
Computer Generations
First-generation of computer
The time period of the first generation computer is from 1946 to 1954. Vacuum tubes also known as electronic valves were used in the first generation of computer. The first generation computer was the digital computer.
Examples of first-generation computer are: Mark I and Electronic Numerical Integrator And Calculator (ENIAC)
Second-generation of computer
The time period of the second generation is from 1955 to 1964. The transistor was used in place of the vacuum tube in a second generation of computers. Ferrite core was used for main memory and magnetic disks were used as secondary memory in second-generation computers. The high-level language was used.
Examples of second-generation computers are IBM 1620 and CDC 3600.
Third-generation of computer
The time period of the third generation of computers is from 1964 to 1977. Integrated circuit(IC) chips were used in place of the transistor. A single Integrated Circuit (IC) chip can contain many transistors, registers, and capacitors.
Examples of Third-generation computers are: IBM-360 and VAX-750.
Fourth-generation of computer
The time period of the fourth generation is from 1978 to 1990. In the fourth generation, VLSI was used. The full form of VLSI is a very large-scale integration. An Integrated Circuit Chip which has more than 1000 components embedded is called VLSI. Personal computers were manufactured in this generation.
Example of Fourth Generation: IBM-PC and Apple-Macintosh
Fifth-generation of computer
The period of the fifth generation is from 1991 to the present. In the fifth generation, ULSI chips came in vague. The full form of ULSI is Ultra Large Scale Integration. In the fifth generation of computer, new technologies are introduced for example AI (Artificial Intelligence) and Machine Learning
