Bus topology - Only one computer is connected to the server
Star topology - Each computer is separately connected to the server
Line topology - Each computer is connected to the one in front of it.

Networking

1.) LAN stands for Local Area Network. It is a small network of computers that are all connected to a server. LANs are usually confined to a small area, such as a building.

2.) WAN stands for Wide Area Network. It is a network that spans over a large distance. They t
typically consist of multiple LANS.

3.) A network topology is how the different parts of a network (Clients, router etc) are arranged connected. For example, a mesh network is when all clients are directly connected to the server.

4.) Mobile network is different to regular ones. An example is 4G, or the smaller 3G network.
