Question Paper
1. Choose the correct answer from the four given alternatives:
Most operating systems are comprised of three main components the the file system and the shell.
desktop
kernel
user interface
code
refers to the ability of multiple processes (or threads) to share code, resources or data in such a way that only one process has access to shared object at a time.
Synchronization
Mutual Exclusion
Deadlock
Starvation
problem occurs due to sharing of resources.
Starvation
Deadlock
Both and
