GENERATIONS OF COMPUTING | WHAT ARE COMPUTER GENERATIONS ?
The word ‘generations of computing’ confuses us. The word human generation can is understandable.
Fathers, sons, grandsons, great-grandsons can be descended from human generations. It consists of a series of births from father to son, from him to grandson.
There is no such thing as a computer. The generation of computers is a phrase. As the nature of computers changed, so did the names of the first generation and the second generation.
Their generation is largely determined by what constitutes the main component of the electrical circuit in a computer.
We are currently living in the age of the fourth generation computer, and the fifth generation is about to come.
Take a look at what the first four GENERATIONS OF COMPUTING | WHAT ARE COMPUTER GENERATIONS were like!
FIRST GENERATION COMPUTER (1951 to 1958)
The first generation of computers was born in June 1951 with the creation of ‘UNIVAC 1’.
The use of computers for trade and industry began at the same time. The results of the 1952 US presidential election were announced by Univac 1 just 45 minutes after the polls closed.
Eisenhower was elected president in the same election. The first generation of computers used mostly vacuum tubes, which caused a lot of problems.
Vacuum ducts will generate heat in the atmosphere, and a large number of air conditioning devices have to be used to reduce it.
Due to the large size of the tubes, the size of the computer became huge. There was no certainty as to when the tube would fail, so a team of technicians had to be hired to maintain the computer.
Needless to say, speed and price! The speed of calculation is low, and the price is skyrocketing! Such was the state of first-generation computers.
They were used only for reasonable work such as payroll, accounts, etc.
SECOND GENERATION COMPUTER (1959-1964)
Transistors were invented after 1958. With the help of transistors, it was possible to do the same work as the vacuum tube. That gave birth to the second generation of computers.
Instead of a vacuum tube, a transistor was a major component in the formation of electrons. The transistor is much smaller in size than a vacuum tube. Of course, the size of the computer also decreased.
The smaller the size of the transistor, the higher the speed, and the lower the required power. This led to a radical change in computers as well.
Their prices plummeted. During this time, magnetic tapes and plates were made, which facilitated the collection of a lot of information.
High-level languages also began to emerge. All of this has benefited second-generation computers.
THIRD GENERATION COMPUTER (1965-1970)
IC or Integrated Circuit was the mainstay of third-generation computers! The technique of carving thousands of tiny electrodes on a very small piece of silicon semiconductor was completed during this time.
Many transistors, resistors, and capacitors were carved in such a small IC. That is why the size and cost of the computer have dropped dramatically.
Its speed also increased many times. The cost of computers has reached the reach of small businesses.
FOURTH GENERATION COMPUTER (1971 to present)
IC is the basis of fourth-generation circuits. During the intervening period, their production underwent a radical improvement. Its shape shrunk even more.
At the same time, the technique of large-scale integrated circuits was established. The microprocessor is a type of IC that is a small standalone computer.
The brain of a modern computer is a microprocessor chip! Microprocessor chips are used in computers like Apple, Commodore, BBC, etc. 6502, Z80 in children’s favorite spectrum, and IBM computer 8088.
The final stage of the fourth-generation computer is a personal computer! At least in Western countries, it will now appear in homes.
Now a fourth-generation computer has been placed on the small table in the house as we call it Personal Desktops or Laptops!
