Commonly Asked by Users

Q1. What are the best ways to practice Networking questions?

Use Networking practice tests and MCQ quizzes available online. Focus on OSI layers, IP addressing, and routing problems.

Q2. Are Networking questions asked in non-IT exams?

Yes, basic Networking is included in technical aptitude sections of PSU, SSC, and Bank IT exams.

FAQ – Frequently Asked Questions on Networking

Q1. What is the OSI model in Networking?

The OSI model has seven layers that define how data travels from one device to another: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Q2. What is the difference between IP and MAC addresses?

An IP address identifies a device on a network logically, while a MAC address is the physical hardware address of a network interface card.

Q3. What is a router used for?

A router connects multiple networks and directs data packets to their correct destination using IP routing tables.

Q4. What is the function of DNS?

DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses.

Q5. What is subnetting?

Subnetting divides a large network into smaller, manageable sub-networks to improve performance and security.

Q6. What is the difference between TCP and UDP?

TCP is connection-oriented and reliable, while UDP is connectionless and faster, used in streaming or gaming.

Q7. How to prepare for Networking MCQs effectively?

Study Networking fundamentals, practice Networking online tests, and review explanations for every question.
