FAQs on Responsibilities of Network Layer Video Lecture - Computer Networks - Computer Science Engineering (CSE)

1. What are the main responsibilities of the Network Layer?
Ans. The Network Layer is responsible for routing data packets from the source to the destination across multiple networks. It also handles logical addressing and provides error checking and packet sequencing.
2. How does the Network Layer ensure data packets reach their intended destination?
Ans. The Network Layer uses routing algorithms to determine the best path for data packets to travel through various networks. It also encapsulates data packets with header information containing the destination address.
3. What is the difference between the Network Layer and the Data Link Layer?
Ans. The Network Layer deals with logical addressing and routing of data packets across networks, while the Data Link Layer is responsible for the physical addressing of devices on the same network and for error detection and correction.
4. Can the Network Layer work without the Physical Layer?
Ans. No, the Network Layer relies on the Physical Layer to transmit data packets across the physical network infrastructure. The Physical Layer handles the actual transmission of data over cables or wireless connections.
5. How does the Network Layer handle congestion in a network?
Ans. The Network Layer uses congestion control algorithms to manage the flow of data packets in a network and prevent network congestion. It may include techniques like packet prioritization or traffic shaping to regulate the flow of data.
