What is generation of computer?
The generation of computer is the evolution of computers when they are basic turned into modern computer. Add a short description.
The First Generation
The First Generation
ENIAC
The first electronic computer was invented in nineteen thirty-seven, Vacuum tubes were used in early computers, ENIAC was the first general-purpose electronic computer, ENIAC weighed twenty-seven tons, stood ten feet tall, and took up eighteen hundred square feet of space as these types of computer takes entire room compare to the modern computer.
Vacuum tubes
Vacuum tubes are the first processors as they made electrical signals, as they are thousands on single ENIAC as this vacuum tubes takes a lot of electricity they made a lot of heat can lead to overheating, as for maintenance is harder as one single tube will replace the entire tubes just to fix it.
Magnetic drum
This is the storage of the first computer. It works like a hard drive but having less storage being in five to one hundred kilobytes having low capacity.
This computer has no screens, operating system, images and videos.
The user relies on punch cards to operate this computer, as these punch cards have holes for information or commands.
In November nineteen fifty-nine, IBM introduced the IBM seven zero nine zero. In shipping it before the seven zero seven zero, the seven zero nine zero became IBM's first Second Generation computer - and a very successful one, To nineteen fifty-nine to nineteen sixty-five.
This generation replace the Vacuum tubes instead they use transistor as this transistor can operate being in minute while vacuum tube takes hours, as transistor being so small it also take less electricity and heat making the entire computer room smaller compare first generation.
This computer storages changes magnetic drum into magnetic tape as it's holds more data compare to magnetic drum.
But they still the same faction to first generation using the punch card to operate the computer.
This is of third generation was from nineteen sixty-five to nineteen seventy-one.
The computers of third generation used Integrated Circuits in place of transistors. A single Integrated Circuit has many transistors, resistors, and capacitors along with the associated circuitry.
The most important part of this generation is they now supported in monitors and keyboard compare it to punch cards, one of first operating system are showing such as Unix and IBM is three sixty.
The interface is different being text base (type and command) compared it to G U I (Graphical User Interface).
The fourth generation was from nineteen seventy-one to nineteen eighty. Computers of fourth generation used Very Large Scale Integrated circuits. V L S I circuits having about five thousand transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.
Created by Marcian Hoff and Ted.
Marcian "Ted" Hoff, Jr. led the team at Intel that defined the architecture of the first single-chip computer C P U.
V L S I stands for Very Large Scale Integration. It refers to the process of creating integrated circuits by combining hundreds to millions of transistors onto a single chip, as introduce C P U, Mother board, Power supply as it small can fit in one unit and can put it to the desk it became as known desktop.
V L S I
As V L S I is so much faster to compare previous generations this generation also introduce G U I (Graphical User Interface).

Floppy disk still exist on this generation but C D and hard drive was been introduced on this generation as they taking over.
