We really are in the 21st century with the 5 generations of computer. Join me as I travel from the past to the present and take a look from where all the computers started up to the modern ones. We can also have an exciting sneak peek of the future generation of computers.
- 1ST GENERATION: VACUUM TUBES
This was used from 1940 to 1956 and could solve one problem at a time. The computation time was on milliseconds.
- 2ND GENERATION: TRANSISTORS
Transistors used magnetic core technology for primary memory and used magnetic tapes and magnetic disks for secondary storage. The instructions were stored in the memory of computer. The computation was on microseconds. This was used from 1956 to 1963.
- 3RD GENERATION: INTEGRATED CIRCUITS
This ran from 1964 to 1971. It had an operating system which allowed different applications to run at the same time. It could compute in nanoseconds. It ran faster and was smaller than the 2nd generation computers.
- 4TH GENERATION: MICROPROCESSORS
Microprocessors are used from 1971 up to the present. New operating systems were developed during this time. It could compute in picoseconds and supports Graphical User Interface (GUI).
- 5TH GENERATION: ARTIFICIAL INTELLIGENCE
Artificial Intelligence try to simulate the human way of thinking. They use chips that are able to store millions of components on a single chip. These computers require large memories.
"Each generation of computer is designed based on a new technological development, resulting in better, cheaper and smaller computers that are more powerful, faster and efficient than their predecessors."
