Processes- Making the System More Responsive and Useful
A method by definition build up of a code execution and resource ownership. A process has two main characteristics, code execution and resource ownership. Every application loaded into memory is represented as a process which is the controlling mechanism in a multitasking system. Operating systems in fact multitask the process representing user programs.
The system becomes more responsive and fully used while processes are multitasked. In many such systems, additional processes may be created by the application to provide concurrent execution within a program. Application efficiency will thus be enhanced because there will be multiple units of execution representing the program. When a new process is created, a copy of code and data are created and execution is initiated. Each process runs independently, but the created process has significant ties to the process that created it.
