Answer Posted / rajdeo kumar vadhwa
concurrency:-
when two processes want to acquire the same resource.
Deadlock:-
Deadlock is a condition when two processes (A,B)require a
single resource at a moment then deadlock condition occurred.
example:
suppose two process A,B require resource 'R' for accessing
and that time process A and B both generate flag 1 for
acquire the resource in this situation no one can access
that resource immediately then deadlock condition occurred.
Starvation:
This is mostly happens in time sharing systems in which the
process which requires less time slot is waiting for the
large process to finish and to release the resources, but
the large process holding the resources for long time
(almost for forever) and the process that requires small
time slot goes on waiting. Such situation is starvation for
small process.
