Features of different generations of computer

Features of first generation of computer:

• They were extremely big in size.
• They had low programming capacity.
• They had low accuracy and reliability.
• They produced huge amount of heat and consumed more electricity.
• The system cost and working cost were high.
• Maintenance problem due to heat.
• Used vacuum tubes.

Features of 2nd generation of computer:

• Transistors were used instead of vacuum tubes.
• The size of these computers were much smaller than 1st generation computers.
• The magnetic core were used as secondary storage.
• Little more faster I/O devices as compared to 1st generation.
• Faster processing speed and was measured in microscond.
• The cost was low than 1st generation's computer.
• They used Assembly level language.
• eg: FORTRAN,COBOL.

Features of 3rd generation of computer:

• Integrated circuits were used.
• The size of this computers became much smaller than 1st and 2nd generation's computers.
• They used magnetic disk and secondary storage.
• They used several high level programming languages like Pascal,FORTRAN, basic, COBOL,etc.
• Reduced in the osdt of 3rd generation of computers.
• Keyboard and moniter were introduced in this period.
• Used operating speed, measured in mono second.
• Faster in I/O devices compared to previous ones.

Features of 4th generation of computer:

• It used LSI and VLSI.
• Smaller in size than previous generation's computers.
• Faster I/O devices.
• Storage capacity of this generation of computer increased in both primary and secondary memory.
• Microprocessor was introduced.
• Networking of computers was developed in this generation computers.
• Multiprocessing, multiprogramming, multimedia and distributed computing was possible.
• Multiuser operating system computer was developed.
• Operating processing speed is very faster and is measured in picosecond.

Features of 5th generation of computer:

• Acceptence of multiprocessor.
• Use of bio-chips.
• Use of AI will make computers intelligent and speak command based.
• Ability to understand natural language.
• PROLOG( programming logic) as operating system.
