Types of Computer

Computer Generations:

"Computer Generation" refers to the advancements of technology, speed, storage capacity and the reduction of the prices and the size of the computers.

(i) First Generation: (1946-1955) - Made by using Vacuum tubes, Examples: ("ENIAC" and "UNIVAC").

(ii) Second Generation: (1956-1965) - Made by using Transistor.

(iii) Third Generation: (1966-1975) - Made by using Integrated Circuits (IC) chips.

(iv) Fourth Generation: (1976-2010) - Made by using Very Large Scale Integration (VLSI) Technology.

(v) Fifth Generation: (2010-Present) - Made by using Artificial Intelligence (AI).

Computer Models:

Models: Depending on shape, sizes and capabilities modern computer are mainly four types.

(i) Micro Computers,

(ii) Mini Computers,

(iii) Mainframe Computers,

(iv) Super Computers

Computer Types:

Based on principle of operations, computers are classified into following three types:

(i) Digital Computers,

(ii) Analog Computers,

(iii) Hybrid Computers.

Intelligence Quotient (I.Q.) of the COMPUTER

How to compute the intelligence quotient (I.Q.) of any object or system or animal:

$Intelligence \;Quotient (I.Q.)$ = $\frac{Mental \;Age\; of\; the\; System}{Chronological \;Age \;of\; the\; System}*100$

Since the Mental Age of the non-living System = 0.

$Intelligence\; Quotient (I.Q.)$ = $\frac{0}{Chronological\; Age\; of\; the\; System}*100$

$I.Q. \; of\; the\; Computer \;System$ = $\frac{0}{Chronological\; Age\; of\; the\; System}*100$

Still the I.Q. of the Computer System = 0.

Q. What is the I.Q. of the computer?

IPO Cycle

Introduction to Computer: -  The computer is a modern electronic machine that can receive data or information and can store & process the data as per instructions and finally can display the results accurately is named as Computer.  

In other words, the computer is a modern electronic device that performs basically three operations in a sequence.  

1. It receives data (an instruction).

2. It processes data (as per instruction).

3. It emits data (output). 

This cycle of operations in a computer is known as input-process-output (IPO) cycle.

Q. 1. What do you mean by IPO cycle in the computer.
