What is Program Maintenance?
Answers
Program maintenance refers to modification of a program after it has been compiled.
There are 4 types of program maintenance :-
1. Corrective maintenance - When an error is found and removed after compilation then this is called corrective maintenance.
2. Adaptive maintenance - To accommodate change in the O.S/System in which the program is used, there is a need to change the program/code also. This is called adaptive maintenance.
3. Preventive maintenance - Identifying the error and trying to avoid them in future run-time is called Preventive maintenance.
4. Perfective maintenance - New technology arise every once in a while in real world. Adapting the new technology and maintaining them is called Perfective maintenance.
