What is it?
Networking is two or more computers linked together
Two common types are Local Area Network (LAN) and Wide Area Network (WAN)

More Types of Networks!Though LAN and WAN are common types of
networks, there are others!Two types are Intranet and Extranet

ExtranetExtranet connects people within company that is
outside of the company Is a secure password protected network that

Network Topology!Networks can be grouped into topology like: Bus
topology, Star topology, and Ring topologyThe topology shows the relation of the device and
network

Differences Between Topologies!
If a networked computer is connected to a hub, it has Star topology, instead of Bus topology
It depends on the physical layout
