Q. Explain about Multi tasking environment?

Multi tasking uses parallelism by:

1) Pipelining functional units are pipe line mutually

2) Simultaneously employing multiple functional units

3) Overlapping I/O activities and CPU.

In multitasking environment there must be a proper mix between data structures and task of a job in order to guarantee their proper parallel execution. 

In multi-tasking the useful code of programme can be reused. The property of allowing one copy of programme module to be used by more than task in parallel is known as reentrancy.  Non-reentrant code may be used just one time during lifetime of programme.  The reentrant codes that can be called many times by various tasks are assigned with local variables.
