* First of all, what is computer Generation?
Computer OF Generation refer to the different stages of technological advancements that have shaped the evolution of computers. Each generation represents a significant leap in hardware and technology. let’s explore some Generation: –
# First Generation.
- The period 1940 to 1956, roughly considered as the First Generation of Computer.
- The first-Generation computers were developed by using vacuum tube or thermionic valve machine.
- The input of this system was based on punched cards and paper tape. however, the output was displayed on printouts.
- The first-generation computers worked on binary- coded ( i . e, language of 0-1).
# Second Generation.
- The period 1956 to 1963 is roughly considered as the period of Second Generation of computers.
- The second-Generation computers were developed by using transistor technology.
- In comparison to the first generation, the size of second generation was smaller.
- In comparison to computers of the first generation, the computing time taken by the computers of the second generation was lesser.
# Third Generation.
- In comparison to the computers of the second generation, the size of the computers of the third generation was smaller.
- In comparison to the computers of the second generation, the computing time taken by the computers of the third generation was lesser.
- The third-generation computer consume less power and also generated less heat.
- The maintenance cost of the computers consumed third generation was also low.
# Fourth Generation.
- The period 1972 to 2010 is roughly considered as the fourth generation if computers.
- the fourth-generation computers were developed by using microprocessor technology.
- By coming to fourth generation, computer become very small in size, it became portable.
- It consumes less power than third generation.
# Fifth Generation.
- The period 2010 to till date and beyond, roughly considered as the period of fifth generation of computers.
- The computers of the fifth generation had high capability and large memory capacity.
- Working with computers of this generation was fast and multiple tasks could be performed simultaneously.
- Some of the popular advanced technologies of th4e fifth generation include Artificial Intelligence, Quantum computation, Nanotechnology, Parallel processing, etc.
