Q: What are the main features of first generation computers?
1. Electronic Components - The main electronic component in this generation was the vacuum tube.
2. Input system - Punch card was used for data input in computer.
3. Output system-- Punchcards and paper were used to display the output.
4. Storage-- Magnetic drums were used as primary school but punch cards were used as secondary storage.
5. Size - The computer was much larger in size.
6. Speed - These computers could execute a thousand commands in one second.
7. Cold Heat Control - A lot of vacuum tubes were used to generate a lot of heat so there was a great need for cold heat control.
8. Maintenance - Regular maintenance was required due to high mechanical disturbances.
9. Programming Language - The language of the program was first machine language and then assembly language.
Q: What are the main features of second generation computers?
1. Electronic components - Transistors were the main electronic components of this generation of computers.
2. Input system - Punchcard and magnetic tape were used for data input.
3. Output system - Output was collected on punchcard and paper.
4. Storage- Magnetic tape was used to store information.
5. Size - Computers were slightly smaller in size than the first generation.
6. Speed - These computers could execute 10000 commands in 1 second.
7. Cold Heat Control- It was necessary to control the cold heat as heat is generated from computers.
8. Maintenance- Mechanical disturbances were less than before but still sufficient maintenance was required.
9. Programming Language- From this generation high level languages like COBOL, FORTRAN, BASIC etc. were used.
