Part A
What is Networking?
Answer
Networking is the practice of connecting two or more computing devices together to share resources, exchange data, and facilitate communication. It involves the use of hardware components, such as routers, switches, and cables, and software protocols that define the rules for data transmission across the interconnected systems.
Write a short note on Routing.
Answer
Routing is the process of selecting the most efficient path for data packets to travel across an interconnected network from a source to a destination. It operates primarily at the Network Layer of the OSI model.
The process involves two main functions: path determination and packet forwarding. Routers maintain routing tables that store information about network topology and reachable paths. Based on these tables, routers decide the next hop for each incoming packet. Routing protocols, such as RIP, OSPF, or BGP, are used to dynamically update these tables to adapt to network changes, congestion, or link failures, ensuring reliable data delivery.
