Q1

What is the primary function of a process control block (PCB)?

A1

PCB stores process state, program counter, CPU registers, memory limits, and open file list. It enables context switching between multiple processes.
Q2

Differentiate between preemptive and non-preemptive CPU scheduling.

A2

Preemptive scheduling allows OS to interrupt a running process; non-preemptive requires process to voluntarily yield CPU until completion or I/O wait.
Q3

How does the Banker’s algorithm prevent deadlocks?

A3

It maintains available, maximum, allocated, and need matrices. It grants resources only if resulting state remains safe, avoiding circular wait.
Q4

What is thrashing in virtual memory?

A4

Thrashing occurs when CPU spends more time swapping pages than executing, due to insufficient physical memory, causing low throughput.
Q5

Name four necessary conditions for a deadlock.

A5

Mutual exclusion, hold and wait, no preemption, and circular wait. All four must hold simultaneously for deadlock to occur.
Q6

What is the role of a dispatcher in CPU scheduling?

A6

The dispatcher switches context from one process to another, switches to user mode, and jumps to proper location. Dispatch latency must be minimal.
Q7

How does semaphore solve the producer-consumer problem?

A7

Use mutual exclusion semaphore for buffer access and counting semaphores for empty/full slots, ensuring producer waits when buffer is full.
Q8

Differentiate between paging and segmentation.

A8

Paging divides memory into fixed-size frames using a page table; segmentation divides into variable-sized logical segments (code, data, stack).
Q9

How does a microkernel differ from a monolithic kernel?

A9

Microkernel runs only essential services (IPC, memory management) in kernel space; user services run as servers. Monolithic kernel integrates all.
Q10

Name two file allocation methods and their trade-off.

A10

Contiguous allocation gives fast access but suffers external fragmentation. Linked allocation eliminates fragmentation but has poor random access.
