Generations of computers

      Generation in computer language may be a amendment in technology employed in computers. Generation includes changes in each hardware and computer code of a ADP system.

There area unit altogether 5  generations of computers as explained below:

First Generation: The amount of initial generation was 1946-1959.

1st Generation
Initial generation of computers started with victimisation vacuum tubes because the basic elements for memory and electronic equipment for C.P.U. (Central process Unit). These tubes like electrical bulbs created plenty of warmth and were liable to frequent fusing of the installations, therefore, were terribly pricey and will be afforded solely by terribly massive organizations.

In this generation, chiefly execution operational systems were used. during this generation, Punched cards, Paper tape, tape Input & Output devices were used.

There were machine codes and electrical wired board languages used.

The main options of initial Generation are :

  • Vacuum tube technology
  • Unreliable
  • Supported Machine language solely
  • Very expensive
  • Generates ton of warmth
  • Slow Input/output device
  • Huge size
  • Need of A.C


Some computers of this generation were:
ENIAC : Electronic Numerical measuring instrument and laptop
EDVAC : Electronic distinct Variable Automatic laptop
UNIVAC: Universal Automatic laptop
IBM701 : International Business Machines - 701 and IBM-650

Second Generation: The amount of second generation was 1959-1965.

        This generation victimisation the semiconductor unit were cheaper, consumed less power, additional compact in size, additional reliable and quicker than the primary generation machines fabricated from vacuum tubes. during this generation, magnetic cores were used as primary memory and tape and magnetic disks as storage device devices.

In this generation, programming language and high-level programme language like : FORTRAN, programing language were used.
There were execution and execution software package used.

The main options of Second Generation area unit :

  • Use of transistors
  • Reliable as compared to initial generation computers
  • Smaller size as compared to initial generation computers
  • Generate less heat as compared to initial generation computers
  • Consumed less electricity as compared to initial generation computers
  • Faster than initial generation computers
  • Still terribly expensive
  • A.C. needed
  • Support machine and assembly languages


Some computers of this generation were:
IBM 1620, IBM 7094, CDC 1604, CDC (Control information Corporation) 3600 and UNIVAC 1108

Third Generation: The amount of third generation was 1965-1971.

3rd Generation

          The third generation laptop is created from Integrated Circuits (ICs) in situ of transistors. one IC has several transistors, resistors and capacitors in conjunction with the associated electronic equipment. The IC was fictitious by Jack Kilby. This development created computers smaller in size, reliable and
efficient.

In this generation, Remote process., Time-sharing, Real-time, Multi-programming software package were used.
High-level language (FORTRAN-II TO IV, COBOL, PASCAL PL/1, BASIC, ALGOL-68, etc.) were used throughout this generation.

The main options of Third Generation are:

  • IC used
  • More reliable
  • Smaller size
  • Generate less heat
  • Faster
  • Lesser maintenance
  • Still expensive
  • A.C. needed
  • Consumed lesser electricity
  • Support application-oriented language

Examples: Some computers of this generation were:
IBM-360 series, Honeywell-6000 series, PDP (Personal information Processor), IBM-370/168
and TDC-316

Fourth Generation : the amount of Fourth Generation was 1971-1980.
<img src="4thgeneration.png" alt="4th generation of computer"/>
4th generation of computer

          The fourth generation of computers is marked by the utilization of terribly massive Scale Integrated (VLSI) Circuits. VLSI circuits having concerning 5000 transistors and alternative circuit parts and their associated circuits on one chip created it potential to own microcomputers of fourth generation. Fourth Generation computers became additional powerful, compact, reliable, and reasonable. As a result, it gave rise to non-public laptop (PC) revolution.

In this generation, sharing, Real time, Networks, Distributed software package were used.
All the upper level languages like C and C++, DBASE, etc., were employed in this generation

The main options of Fourth Generation are:

  • VLSI technology used
  • Very cheap
  • Portable and reliable
  • Use of PC's
  • Very tiny size
  • Pipeline process
  • No A.C. needed.
  • Concept of web was introduced
  • Great developments within the fields of networks
  • Computers became simply on the market

Some example computers of this generation were:

  • DEC ten (Digital instrumentation Corporation)
  • STAR one thousand
  • PDP eleven by ten (Digital instrumentation Corporation)
  • CRAY-1 (Super Computer)
  • CRAY-X-MP (Super Computer)


Fifth Generation: the amount of Fifth Generation is 1980-till date.

5th generation of computer

        In the fifth generation, the VLSI technology became ULSI (Ultra massive Scale Integration) technology, leading to the assembly of silicon chip chips having 10 million electronic elements.

        This generation is predicated on data processing hardware and AI (Artificial Intelligence) computer code. AI is associate rising branch in applied science that interprets means that and strategies of creating computers assume like folks. AI includes artificial intelligence, Neural networks, Game enjoying, Development of knowledgeable systems to create choices in world things and language understanding and generation.

All the upper level languages like C and C++, Java, .Net, etc., area unit employed in this generation.

The main options of Fifth Generation are:

  • ULSI technology.
  • Development of true computer science.
  • Development of language process.
  • Advancement in data processing.
  • Advancement in Superconductor technology.
  • More user friendly interfaces with transmission options.
  • Availability of terribly powerful and compact computers at cheaper rates.


Some example computers of this generation are: Desktop, Laptop, Notebook, Ultrabook
and Chrome Book.

I hope you my dear friends today we are know the generations of computers comment below your reviews ..Thanks for visit us.
