This is the Computer Fundamental Notes portion here we are focus on Generation of Computer under computer fundamental notes.
Classification of computer in different time period on the basis of their technological development is known as Generation of Computer. There are five ‘5’ generation of computer which is mention below.
Table of Contents
First Generation Computer (1940-1950)
| Technology | Vacuum Tube |
| Input | Punched Card |
| Output | Paper |
| Storage Device | Magnetic Drums, Magnetic Tapes |
| Size | Large, Bulky |
| Speed | Very Slow (Measured in Millisecond) |
| Example | ENIAC, EDSAC, EDVAC, IBM-650,702,705 |
Second Generation of Computer (1950-1960)
| Technology | Transistor |
| Input | Punched Card |
| Output | Paper |
| Size | Smaller Compare to 1st generation |
| Storage Device | Magnetic core memories |
| Speed | Faster (Measured in Microsecond) |
| Example | IBM 7000, ATLAS, MARK-III, Honeywell-200 |
Third Generation of Computer (1960-1970)
| Technology | Integrated Circuits (IC) |
| Input Device | Punched Card, Keyboard |
| Output Device | Paper, Monitor |
| Storage Device | Semi Conductor Memory, Magnetic Disk, Magnetic Tape |
| Size | Smaller compare to previous generation |
| Speed | Faster compare to pervious generation (Measured in Nanosecond) |
| Used Operating System | |
| Example | IBM 360, ICL 2900 |
Fourth Generation Computer (1970 to Present)
| Technology | Microprocessor |
| Input Device | Keyboard, Mouse, Scanner, Digitizer |
| Output Device | Paper, Monitor, Printer, Plotter |
| Storage | Semiconductor Memory, Magnetic or Optical Disk (CD/DVD) |
| Size | Smaller than third generation computer |
| Speed | Faster then third generation computer (Picoseconds) |
| Example | Pentium Series computers, IBM System 370, HP- 3000 |
Fifth Generation Computer
- Will be based on Biochips
- Will have Artificial Intelligence (AI)
- Will have ability to solve problem themselves
- Will recognize voice, image etc.
- These computer have larger memory requirements.
- They try to simulate the human way of thinking and reasoning.
