UNIT 1 
INTRODUCTION TO COMPUTERS
1. What is a computer?
 The computer is an electronic machine that takes input from the user and processes it to generate the output in the
form of useful information.
2. What is a program?
 A program is a set of instructions that can be executed one-by-one in thecomputer.
 Each program performs certain task that is created by the user.
3. What is Hardware and Software?
 Hardware of the computer means, all the visible components of a computer that are needed for proper functioning.
It is the framework. Software is applied on the hardware of the computer. E.x: CPU, monitor,etc
 Software of the computer means, the set of programs that can be executed one by one in acomputer.
It controls all the operations of a computer. Ex: OS, games softwares,etc
4. What is the difference between application software and system software?
 System softwares are inbuilt softwares that are required to start thecomputer.
 Without system software, a computer cannot work properly. Ex : Windows OS, Linux OS, DOS,etc
 Application softwares are optional softwares that are needed to perform certain task needed foruser.
 Without application software, a system can work. Ex: Tally, Games softwares, etc
5. What are the advantages and disadvantages of first generation ofcomputers?
Advantages:
 Based on vacuum tube technology
 During that time, these type of computers
were the fastest.
 Calculations are done in milliseconds.
Disadvantages:-
 Large space is needed.
 It takes more power
 Very costly
 No reliability
 Programming is difficult
6. What are the advantages and disadvantages of second generation ofcomputers?
Advantages:
 Based on transistor technology
 Small in size
 Less heat produced
 Calculations are done in microseconds
 Better reliability
Disadvantages:-
 Very costly
 It needed AC
 Production was difficult
7. What are the advantages and disadvantages of third generation ofcomputers?
Advantages:
 Based on IC (Integrated Chip) technology
 Calculations are done in nano seconds
 Less power needed
 Less maintenance cost
 More reliability
Disadvantages:-
 It needed AC
 Production was difficult
8. What are the advantages and disadvantages of fourth generation of computers?
Advantages:
 Based on Processor technology
 Small in size
 Portable and very much reliable
 Less maintenance cost
 All programming languages aresupported
Disadvantages:-
 Production was difficult
9. What are the advantages and disadvantages of fifth generation of computers?
Advantages:
 Portable
 User friendly
 Supports many OS
 Supports parallel programming
 High speedcalculations
 Large storage capacity.
Disadvantages:-
 There is no program that makes the computer to
operate completely automatic.
