World of Computer Networking Your CCNA start - Routers

The video tutorial covers the types of IP addresses: unicast, multicast, and broadcast. It defines routers as network devices responsible for routing IP packets on the network layer of the TCP/IP model. Routers operate on physical, data link, and network layers, possessing ports with MAC and IP addresses. They not only forward packets but also discover remote networks using routing protocols. These protocols facilitate the exchange of network information between routers, enabling them to build routing tables and find optimal paths for packet delivery. The tutorial concludes with a brief mention of local and wide area networks.

Explain the process of encapsulation and decapsulation performed by routers.

What is the difference between a local area network and a wide area network?
