Classification of generations of computers From 1st generation to 5th Generation |

 

Introduction to pc generations

This development amount of electronic computing technology is termed pc generation.

 

 

 

 

 

 First Generation of pc (1940-1956)

This 1st generation of computers was supported electronic device technology used for calculations, storage, and management, unreal in 1904 by John Church Father Fleming. The vacuum tubes and diode valves were the chief elements of the primary generations of computers.

First-generation computers relied on the lowest-level machine language, so as to perform operations, and will solely solve one drawback at a degree of your time.

 

Magnetic drums were used because the memory in these computers (were terribly slow in speed). The punched and magnetic tapes were used for the input and output perform of the pc so as to show on prints even the results weren’t 100% correct.

2nd Generation of pc (1956-1964)

The second generation of computers replaced the vacuum tubes with a reliable part referred to as transistors for producing of computers was unreal by Shockley in 1947.

The transistors were the revolution within the pc field as a result of this part privileged the ordinal information pc by increasing the performance, operative speed (hundreds of thousands of operations per second), also as decreasing the electricity consumption of the computers.

 Third Generation of pc (1964-1971)

The third generation appeared within the kind of integrated circuits (invented by Jack Kilby from 1958 to 1964). Associate in Nursing IC (integrated circuit) is consists of the many tiny transistors mounted on chips, that square measure referred to as semiconductors.  

This synchronous chip became a crucial basis for third-generation computers once scientists combined many transistors that match into this circuit, leading to an additional powerful electronic section referred to as Associate in nursing computer circuit.

 

Multi-programming was enforced at a similar time (this happens once there square measure many viable programs in memory) that reduced their producing prices. Within the mid-60s. IBM refined the term "computer architecture". By the late 60's. Mini computers appeared.

This revolutionary innovation allowed to extend the process capability and memory of machines.

4th Generation of pc (1971-2010)

The silicon chip brought the fourth generation of computers, as thousands of integrated circuits such as concerning a lot of transistors were assembled and brought the entire central process unit and different basic components of the machine into a little chip referred to as a silicon chip fitted on the C.P.U. socket. These computers used terribly massive Scale Integrated circuits technology conjointly referred to as VLSI technology. When the invention, the silicon chip began to be utilized in computing machines within the fourth and fifth generations of computers.

 

With the framework of the thought-about generation in 1971, the primary silicon chip appeared as associate in nursing surprising results of Intel's work on calculator circuits and additional development of minicomputers (PDP-11).

5th Generation of pc (2010-At Present)

Artificial intelligence is that the name of the fifth also because the latest generation of computers supported ULSI (Ultra massive Scale Integration) technology is that the method of group action or embedding a lot of transistors on one atomic number 14 semiconductor unit.
