Q5. Give examples for each of system software and application software. Explain the function of each type.
Ans. Examples of system software are:
(i) Operating System
(ii) Language Processor
(iii) Application Software
Examples of Operating System are: Single user OS, multiuser OS, batch processing OS, multiprocessing OS, etc.
As the name suggest, single user OS supports single user whereas multiuser OS can support multiple users. The batch Processing OS process the batches (groups) of jobs (processes given to it) and multiprocessing OS is capable of handling multiple CPUs at the same time. The examples of language processors are:
An interpreter converts and executes a high level language program into object program line by line whereas a complier converts a high level language program into object program in one go and once the program is error free, it can be executed later. An assembler converts an assembly language program into object program.
Examples of application software are:
(i) Customized Software
(ii) General Software
The customized software pertains to the requirements of a specific user for whom the software has been developed. General software is developed keeping in mind general specification of a problem.
