Answer:
Introduction to Computer Generations
This development period of electronic computing technology is called Computer Generation. There are five generations of computers identified, although the sixth generation could be in development now in the early 21st century.
During the evolutionary timeline, each generation of computers has improved a lot by undergoing considerable changes in their size, type, and functionality.
By analyzing them, one can trace the evolution of computer technology, to see how the computer industry has changed over the years and how great capabilities and software progress has been made by humankind in under a hundred years, as a result, the creation of different generations.
At present, the computer is playing a significant part in human existence because today’s digital computer is being used for every work in each field. If someday an issue occurs in the computer or the server is down, at that point all the work stops. This is how significant it is for technology development!

Generations of Computer From 1st to 5th
Generations of Computer 1st to 5th
Let’s discover the series of computer generations in the following list:
1st Generation of Computer (1940-1956)
This first generation of computers was based on vacuum tube technology used for calculations, storage, and control, invented in 1904 by John Ambrose Fleming. The vacuum tubes and diode valves were the chief components of the first generations of computers.

First-generation computers relied on the lowest-level machine language, in order to perform operations, and could only solve a single problem at a point of time.
Magnetic drums were used as the memory in these computers (were very slow in speed). The punched and magnetic tapes were used for the input and output function of the computer in order to display on prints even the results weren’t 100% accurate.

Also, the first generation of computers available was based on the 8-bit microprocessor.
The disadvantages of 1st gen computers are that they were very enormous in size and heavy in weight (made of thousands of vacuum tubes), occupying large rooms. Also, once they were kept in one place it was difficult to transfer. Another con like using a decimal number system and many switches and cables.
In addition, they were also very expensive to operate with using a large amount of electricity, the vacuum tubes produced large amounts of heat, so an air conditioner was required for the proper functioning unless a lot of heat can cause a malfunction.
The advantage of the first generation of computers is that they could calculate in milliseconds (about five thousand sums per second.)
