Q. Explain the Concept of Process?
A process is sequential program in execution. A process states the basic unit of computation for the computer. Components of process are:
1. Object Program
2. Data
3. Resources
4. Status of the process execution.
Object program i.e. code to be executed. Data is used for executing the program. While executing the program it may need some resources. Last component is used for verifying the status of process execution. A process can run to completion only when all requested resources have been allocated to the process. two or more processes can be executing the same program, each using their own resources and data.
