Wide Area Networks (WANs) with respect to class 8 Networking
Local Area Networks (LANs) with respect to class 8 Networking
Ethernet LANs – Communication-based on a bus topology.
Token ring LANs – Communication-based on the ring topology
FDDI LANs – Communication uses optical fiber and is based on the token ring mechanism where two rings flow in the opposite directions.

Internet Protocol (IP) with respect to class 8 Networking –
The main functions of Internet protocol are
→ Firstly, the information is decomposed into packets of standardized size and then reassembled at the destination.
→ It also routes a packet through networks, from the source to the destination which is identified by its IP address.
Networking
With respect to class 8 computer lessons, a network can be simply defined as a group of computers and other devices connected in order to exchange data.
There are two principal kinds of networks
Wide Area Networks (WANs) and Local Area Networks (LANs)
OSI Layers
