This section provides a comprehensive collection of questions and answers that
cover a wide range of networking concepts. These questions can help students
understand the key topics of networking and prepare for exams or discussions on
the subject.
1. What is networking?
Answer:
Networking is the practice of connecting computers and other devices together to
share resources, exchange data, and enable communication. It involves hardware
devices like routers, switches, and cables, as well as software protocols that
manage the transmission of data across the network.
2. What are the types of networks?
Answer:
The main types of networks are:
LAN (Local Area Network): A network that connects devices within a
limited area like a home, office, or school.
WAN (Wide Area Network): A network that spans large geographical areas,
such as cities or countries.
MAN (Metropolitan Area Network): A network that connects devices
within a city or large metropolitan area.
PAN (Personal Area Network): A network that connects personal devices
like smartphones, laptops, and wearables within a limited range.
, 3. What is the OSI model, and how many layers does it have?
Answer:
The OSI (Open Systems Interconnection) model is a conceptual framework used
to understand how different networking protocols interact within a network. It
has seven layers:
1. Physical Layer – Deals with the physical hardware of the network.
2. Data Link Layer – Responsible for node-to-node data transfer.
3. Network Layer – Handles routing and addressing of data packets.
4. Transport Layer – Ensures reliable data transfer between devices.
5. Session Layer – Manages and controls the sessions between devices.
6. Presentation Layer – Deals with data format translation and encryption.
7. Application Layer – The layer closest to the end-user, where applications
interact with the network.
4. What is the TCP/IP model?
Answer:
The TCP/IP model is a suite of protocols used for communication over the
internet. It consists of four layers:
1. Link Layer – Deals with the physical and data link aspects of
communication.
2. Internet Layer – Responsible for routing data across networks (e.g., IP
protocol).
3. Transport Layer – Ensures end-to-end communication and data integrity
(e.g., TCP and UDP).
4. Application Layer – Provides the interface for network applications to
communicate (e.g., HTTP, FTP).
