Operating Systems - Process vs Thread - Key Differences

You are designing a web server that must handle thousands of simultaneous client requests efficiently. Which approach is most suitable to maximize resource sharing and minimize overhead?

AUse multiple threads within a single process to handle client requests concurrently

BUse multiple processes with shared memory segments for communication

CUse a single-threaded process with blocking I/O for all requests

DUse multiple processes, each handling a single client request independently

Step-by-Step Solution

Step 1: Understand resource sharing in threads
Threads within the same process share memory and resources, allowing efficient communication and lower overhead compared to processes.
Step 2: Compare overhead of context switching
Thread context switching is lighter than process context switching, making threads better for high concurrency.
Step 3: Evaluate options
Use multiple processes, each handling a single client request independently uses processes, which have higher overhead and less efficient resource sharing. Use a single-threaded process with blocking I/O for all requests is single-threaded and blocks, limiting concurrency. Use multiple processes with shared memory segments for communication adds complexity with shared memory and still has process overhead.
Final Answer:
Option A -> Option A
Quick Check:
Threads maximize resource sharing and minimize overhead for concurrent tasks [OK]

Quick Trick: Threads share memory; processes isolate resources [OK]

Common Mistakes:

MISTAKES

Assuming processes are always better for concurrency
Ignoring context switching overhead differences
Believing shared memory between processes is as simple as threads

Trap Explanation:

PITFALL

Processes provide isolation but at the cost of overhead; threads share memory but require careful synchronization.

Interviewer Note:

CONTEXT

Tests candidate's ability to recognize when threads are preferable over processes for concurrency and resource sharing.
