Q1. Write code for encapsulation and decapsulation
Ans. 
Encapsulation and decapsulation are processes used in data communication to wrap and unwrap data packets.

• Ports are placed in different states: blocking, listening, learning, and forwarding.

• Example: In a network with multiple switches, STP will block certain links to ensure a single a...read more
