2. Generations of
Computer
Generations Timeline Evolving Hardware
First Generation 1940s-1950s Vaccum tube based
Second Generation 1950s-1960s Transistor based
Third Generation 1960s-1970s Integrated circuit based
Fourth Generation 1970s-Present Microprocessor based
Fifth Generation Present and the future Artificial Intelligence
Based

3. Characteristics of First Generation
of Computers(1940s-1950s)
 Main memory- magnetic
drums & magnetic tapes.
 Programming language-
machine language
 Power- consumes lot of
electricity
 Example- ENAIC,
UNIVAC1, IBM 650, etc.

4. Characteristics of Second
Generation of Computers(1950s-
1960s)
 Memory- magnetic core
& magnetic tape/disk.
 Programming language-
assembly language
 Power- low power
consumption
 Example- UNIVAC 1107,
IBM 1401, IBM 7090 &
7094, etc.

5. Characteristics of Third Generation
of Computers(1960s-1970s)
 Memory-large magnetic
core & magnetic tape/disk.
 Programming language-
high level
language(FORTRAN,
BASIC,COBOL, etc.)
 Size- smaller, cheaper &
more efficient than second
generation computers.
 Example- UNIVAC 1108,
IBM 360, PDP-11,etc.

6. Characteristics of Fourth
Generation of Computers(1970s-
Present)
 Memory- semiconductor
memory such as
RAM,ROM,etc.)
 Programming language-
high level language
(Python, C#, Java, Rust,
Javascript, etc.)
 Size- smaller, cheaper &
more efficient than third
generation computers.
 Example- IBM PC, STAR
1000, APPLE II,etc.

7. Characteristics of Fifth Generation
of Computers(Present & Future)
 Based on artificial
intelligence uses ULSI
technology & parallel
processing method.
 Language-Understands
human language
 Power- consume less
power & generate less heat.
 Size- Portable & small in
size.
 Example-
desktops,laptops,
smartphones,tablets,etc.
