Generations of Computer

PREVIOUS NEXT

Generation of computer refers to the change in technology that was formerly used. We have five (5) generations of computers which includes the following below:

First Generation

YEAR: 1946 - 1956
This generation made use of vacuum tubes, which was not very efficient as it consumes a lot of electricity while working. Examples of first generation computers are: ENIAC (Electronic Numerical Integrator and Computer), UNIVAC (Universal Automatic Computer), IBM-701 etc.

First-Generation-Computer

Second Generation

YEAR: 1956 - 1963
This generation made use of transistors, which was better than vacuum tubes, as it minimizes energy consumption and was able to work faster than that of vacuum tubes. Examples of second generation computers are: IBM-1620, IBM-7094, CDC-3600, UNIVAC-1108 etc.

Second-Generation-Computer

Third Generation

YEAR: 1964 - 1971
This generation replaced transistors with integrated circuits. Due to this change the size of computer was reduced and made easy to operate. This generation also came with keyboards, joy-sticks etc. Examples of third generation computers are: IBM-360 series, Honeywell-6000 series, PDP (Personal Data Processor), TDC-316 etc.

Third-Generation-Computer

Fourth Generation

YEAR: 1971 - 2010
This generation came with microprocessor (an integrated circuit). This help to drastically miniaturize computer's structure, boost performance and speed amongst others. Not only was keyboards and joy-sticks seen here in this generation but also mouse and printer. Examples of fourth generation computers are: DEC-10, STAR-1000, CRAY-1, PDP-11 etc.

Fourth-Generation-Computer

Fifth Generation

YEAR: 2010 - Present
This is the present day computers, which are very much faster, smaller and more intelligent. It uses Ultra Large Scale Integration, parallel processing hardware and artificial intelligence. Examples of computer in this generation are: Laptops, Desktop, UltraBook, NoteBook, Robots, etc.
