A. Fundamentals of Computer NetworkingTop of Form
1) Definition, Need, and Applications
Computer networks refer to interconnected systems enabling data sharing and communication between devices. They facilitate resource sharing, efficient communication, and remote access.
The need for computer networks arises from the demand to share resources, facilitate rapid data transfer, enhance communication, and ensure reliability through redundancy.
Applications include business collaboration, communication tools (email, video conferencing), education platforms, entertainment (online gaming, streaming), research collaboration, and infrastructure management in smart cities and IoT setups.
2) Classification Of Networks
LAN (Local Area Network): Covers a small geographical area like an office, building, or campus. Usually, they are privately owned and offer high data transfer rates.
MAN (Metropolitan Area Network): Spans a city or a large campus, connecting multiple LANs.
WAN (Wide Area Network): Encompasses a broad geographical area, often connecting multiple cities or countries. The internet is the largest WAN, providing global connectivity.
Client-Server: Follows a centralised model where servers provide resources or services to clients (devices) upon request. It's common in business environments.
II. ACKNOWLEDGEMENT
