Process Management

Question 0

What is starvation

Answer 0

When a process never gets access the the resource it requires

Question 1

What are deadlocks

Answer 1

A situation where two or more processes each are waiting for resources held by others

Question 2

What are race conditions

Answer 2

2 or more processes competing for a shared resource

Result varies according to order of process execution

Question 3

How do we avoid race conditions

Answer 3

Using critical sections

Both processes stop in critical sections (where shared resource is needed). And process the critical sections together

Question 4

What is mutual exclusion

Answer 4

Only one process must be allowed to be in a critical section at one time

Question 5

What is disabling interrupts

Answer 5

Disabling interrupts before a process enters its critical section

This guarantees that the process can use this shared resource

Question 6

What is a disadvantage to disabling interrupts

Answer 6

The process may never enable interrupts therefore crashing the computer

Question 7

What strict alternation

Answer 7

When an integer variable keeps track of whose turn it is to enter the critical region
