Study Notes
Network Layer in the OSI Model
- The Network Layer corresponds to Layer 3 of the OSI model.
Responsibilities of the Network Layer
- The primary responsibility of the Network Layer is to route data between nodes on different networks.
Logical Addressing in the Network Layer
- The main function of logical addressing in the Network Layer is to identify devices at the network layer level.
- Logical addressing enables devices on different networks to communicate with each other.
Concepts in the Network Layer
- The concept of routing is fundamental for establishing communication paths in the Network Layer.
IP Addresses in the OSI Model
- IP (Internet Protocol) addresses are used for logical addressing in the Network Layer, which corresponds to Layer 3 of the OSI model.
Test your knowledge of the fundamental concepts of the Network Layer including the structure of the Internet, the role of IP addresses, the functioning of IP packets, the use of forwarding tables, and principles behind routing.
