What is theEvolution of the computer?
- The evolution of computers started around the 16th century. The evolution of the computer
is the process of transforming the oldest vacuum tube-based system to the current model
system of today’s computers. Long ago, the early primitive people were trailblazers in the use
of counting tools, making use of objects like sticks, stones, and bones for their counting
needs. The computer we see today has faced many changes, for the betterment via the
history of computers. It has continuously improved itself in terms of speed, accuracy, size,
and price to urge the form of the computer we have today. Here we have discussed the 5
generations of computers and their characteristics.

First Generation Computers
-The1st
Generation Computers were introduced using the technology of vacuum tubes which
can control the flow of electronics in a vacuum. These tubes are usually used in switches,
amplifiers, radios, televisions, etc. The First Generation of Computer was very heavy and large
and were not ideal for programming. They used basic programming and didn’t have an
operating system, which made it tough for users to do programming on them. The 1st
Generation Computers required a big room dedicated to them and also consumed a lot of
electricity.
Example of main first generation computer are:
1. ENIAC: Electronic Numerical Integrator and Computer, built by J. Presper Eckert and John
V. Mauchly which contained 18,000 vacuum tubes.

2. Second Generation
Computers
-The Second Generation of Computers
revolutionized as it started using the technology of
transistors instead of bulky vacuum tubes.
Transistors are devices made of semiconductor
materials that open or close a circuit. These
transistors were invented in the Bell Labs which
made the Second Generation Computer powerful
and faster than the previous ones. Transistors
made these computers smaller and generated less
heat compared to the vacuum tubes they replaced.
The Second Generation of Computers also
introduced the use of CPU, memory and
input/output units. The programming languages
used for the second-generation computers were
FORTRAN (1956), ALGOL (1958), and COBOL
(1959).

3. Third GenerationComputers
The evolution of Third Generation Computers took
place with a shift from transistors to integrated
circuits also called IC. The Third Generation of
Computers was known for being very fast and
dependable. These computers used Integrated
Circuits (Ics) made from silicon, known as silicon
chips. Each chip contains many tiny electronic
parts, like transistors, registers, and capacitors, all
on a thin piece of silicon.
This made computers in this generation more
powerful and efficient with better memory. During
this time, programming languages like BASIC
(Beginners All-purpose Symbolic Instruction
Code) were commonly used. Also, Minicomputers,
which are smaller than mainframes but still
powerful, were introduced. Overall,this generation
marked significant improvements in speed,
reliability, and capabilities of computers.
59.

devices.
60.
4. Fourth GenerationComputers
- The period from 1972 to 2010 is considered the
period of the fourth generation of computers.
Microprocessor technology was used to develop
the Fourth Generation of Computers. The
foremost advantage of these computers is that
the microprocessor can contain all the circuits
required to perform arithmetic, logic, and control
functions on one chip. In the Fourth Generation,
computers became very small in size and also
became portable.
-Technologies like
multiprocessing,multiprogramming, time-sharing,
operating speed, and virtual memory were also
introduced by then. During the fourth generation,
private computers computer and networks
became a reality.
