Generation of computer ⋆ csestudy247

Evolution of computer is categorized by increasing processor speed, increasing memory size increasing input output capacity and speed.

Table of Contents

First Generation{1942-1964}

It is a un Reliable and very costly.
Support machine language only.
Generate lot of heat.
Slow in process.
Huge in size not portable.
consume lot of electricity.

EX:-ENIAC, EDVAC, UNIUAC, IBM-7401

Second Generation {1952-1964}

In this Generation use to Transistors
It is Reliable Than first
Smaller in size than first.
Consume less electricity and portable than first.
Less heat generation
Faster than first
Support machine Language and Assembly language
Still very costly.
Some example of second Generation of computer.

IBM1620, IBM7094, CPC1604

Third Generation {1964-1971}

In this Generation is used to integrated circuit.
More reliable and smaller in size.
Still costly and less heat produce.
Portable
Consume less electricity and faster.
Support high level language

Some example:-IBM-360 Series, FMB-360, Honcy well 6000 series

Fourth Generation{1971-1990}

In this generation is used to VLSI technology. The stands for VLSI is Very Large Scale Integration.
Microprocessor come in use.
Less costly portable and Reliable.
Smaller in size and use pc
Easily available in the market.

EX:-DEC-10,STAR-1000,CARY-1

Note:-

CRAY-1 is the first supper computer.

Fifth Generation{1990-Present}

In this generation is used to ULSI Technology. The stands for ULSI is Ultra Large-Scale Integration.
Development of AI (Artificial intelligent)
Advancement in parallel processing.
More reliable and smaller in size(computer)
Availability of very powerful and compact computer a less price.

EX:-Desktop, Laptop, Notebook,

Families of computer

There are two types of computer Families

1.Intel Pentium series

2.Power PC

1.Intel Pentium series:-

♣ In term of market intel most suited intel use to development of microprocessor one after another every four year.

(a) 8080 Microprocessor:-

♣ Word first general purpose micro processor.

This was 8 bit.

(b) 8085 Microprocessor:-

It is extended from of 8080.

It is also 8 bit.

♣ It is more powerful than previous developed microprocessor.

It is 16 bit Microprocessor.

(d) 80286 Microprocessor:-

It is 16 bit Microprocessor.

(e) 80386 Microprocessor:-

It is 32 bit Microprocessor.

(f) Pentium :-

It is use super scale technique.

(g) Pentium-2:-

It is designed for audio, video and Graphic technology.

(h) Pentium-3:-It was 3D Support.

(i) INTEL Core i₃ processor

(j)INTEL Core i₅

(k) INTEL Core i₇

2. POWER PC (Personal computer):-

(a) 601:- It is 32 bit microprocessor developed in 1986.

(b) 603:- Mainly used in desktop in 1986.

(d) 740/750:-G₃ PROCESSOR

(e) G₄ PROCESSOR

(f) G₅ PROCESSOR
