Computer Networks Practice Test: OSI Model - Network Layer — Flashcards

Network Layer topics include: OSPF and its configuration, datagram networks, firewalls, ethernet, network management and utilities.

The network layer is a part of online communication that connects and transfers data packets between different networks or devices. It's the third layer of the OSI model. 

The network layer's functions include:
Source-to-destination delivery: The network layer is responsible for delivering packets across multiple networks.
Managing logical paths: The network layer manages and selects the best logical path for data transfer between nodes.
Containing the Internet Protocol (IP): The network layer contains the Internet Protocol (IP), which is the standard for routing packets across interconnected networks.
