write the generations of computer and components used in each generation in evolution of computers
Answers
Explanation:
Computers are such an integral part of our everyday life now most people take them and what they have added to life totally for granted.
Even more so the generation who have grown from infancy within the global desktop and laptop revolution since the 1980s.
The history of the computer goes back several decades however and there are five definable generations of computers.
Each generation is defined by a significant technological development that changes fundamentally how computers operate – leading to more compact, less expensive, but more powerful, efficient and robust machines.
1940 – 1956: First Generation – Vacuum Tubes
These early computers used vacuum tubes as circuitry and magnetic drums for memory. As a result they were enormous, literally taking up entire rooms and costing a fortune to run. These were inefficient materials which generated a lot of heat, sucked huge electricity and subsequently generated a lot of heat which caused ongoing breakdowns.
1956 – 1963: Second Generation – Transistors
The replacement of vacuum tubes by transistors saw the advent of the second generation of computing. Although first invented in 1947
1964 – 1971: Third Generation – Integrated Circuits
By this phase, transistors were now being miniaturised and put on silicon chips (called semiconductors).
