Correct Answer - Option 2 : 1.II 2.IV 3.III 4.I
The correct answer is 1.II 2.IV 3.III 4.I
-
Generation in the computer is nothing but the evolution in different forms of computer.
-
Every time new hardware technology is used.
- Each generation involves different hardware and software components that make it form a Computer system.
- There is a total of 5 Generations known to date.
- Each generation has different characteristics that are shown in the table below.
Generation of computers |
Features |
Examples and Images |
1st Generation |
- The period of the first generation of computers is 1946-1959.
- In this generation, Vaccum tube technology was used.
- Computers of this generation generate a large amount of heat.
- Therefore, these computers are not reliable and so expensive.
- The size of these computers is very big.
- These computers support machine Language only.
|
|
2nd Generation |
- The period of the second generation was from 1959-1965.
- In this generation, Transistors were used.
- Transistors generate less amount of heat and more reliable as compared to first-generation computers.
- Computers of this generation are cheap and smaller in size than that of the 1sr generation.
- In this generation, assembly language and high-level programming languages like FORTRAN,
- COBOL was used.
|
- IBM 1620
- IBM 7094
- CDC 1604
|
3rd Generation |
- The period of the third generation was from 1965-1971.
- Here IC's(Integrated Circuits) are used in place of Transistors.
- A single IC has many transistors, resistors, and capacitors along with the associated circuitry.
- Due to this computer smaller in size, reliable and efficient.
|
- IBM-360 series
- Honeywell-6000 series
- PDP (Personal Data Processor)
- IBM-370/168
|
4th Generation |
- The period of the fourth generation was from 1971-1980.
- In this generation, very large integrated circuits (VLIC)were used.
- VLIC has 500o transistors on a single cheap made it possible.
- These computers are more affordable, reliable, and compact.
- In this generation Real-time, the time-sharing operating system was used.
- All the high-level languages like C, C++ were used in this generation
|
- DEC 10
- STAR 1000
- PDP 11
- CRAY-1(Super Computer)
- CRAY-X-MP(Super Computer)
|
5th Generation |
- The period of fifth-generation is the 1980-till date.
- In this generation, VLIC is replaced by ULSI.
- ULSI is ultra large scale integration.
- This generation is based on Artificial Intelligence.
- AI is a branch in the computer which means and interpret to think computers like human brains.
- All the high-level languages
- like C and C++, Java, .Net, etc., are used
- in this generation.
