Question 1

What is a deadlock in operating systems?

Accepted Answer

A situation where processes wait indefinitely for resources held by each other

Answer

A deadlock occurs when two or more processes are permanently blocked, each waiting for resources that are held by the other.

Question 2

What is paging in memory management?

Accepted Answer

Dividing memory into fixed-size frames and mapping process pages to them

Answer

Paging divides physical memory into fixed-size frames and process memory into equal-sized pages, allowing non-contiguous memory allocation.

Question 3

What is the role of the kernel in an operating system?

Accepted Answer

Acting as the core that manages hardware resources and system calls

Answer

The kernel is the OS core that manages CPU, memory, and I/O resources, providing system calls as the interface between applications and hardware.

Question 4

What does CIDR notation represent in networking?

Accepted Answer

A compact method to express IP addresses and their network prefix length

Answer

CIDR (Classless Inter-Domain Routing) notation expresses an IP address with a slash and prefix length (e.g., 192.168.1.0/24) to define address ranges.

Question 5

What is context switching in an operating system?

Accepted Answer

Saving and restoring process state when the CPU switches between processes

Answer

Context switching saves the current process's state (registers, program counter) and restores another process's saved state to enable multitasking.
