You should then focus on the different types of networks and the advantages/disadvantages of them over each other. There are 4 networks to learn
1. Bus network
2. Ring network
3. Mesh network
4. Star network

Dear Sir,
What is the difference between a hub, a switch, a modem and a proxy server
Thank you

A hub is a device used to connect computers together to form a LAN.
A switch is used to send messages between the connected computers
A Modem is used to convert the data from analogue form into digital form.
A proxy server is used to allow networked computers to connect to the internet.

 

[ZainH]

^Also if a question asks to list devices that are used to connect 2 networks you can use any of them.
Hub and switches have the same purposes, to join computers together to form a network (LAN or WAN)
The difference is that a hub sends all incoming data to all of its ports regardless of whether a computer wants it or not, a switch only sends the data to the computer that requested it. This is why we call a hub a "dumb" device.

what are mesh networks ? i know ring and star and bus but what is mesh :S ?

A mesh network is a sort of like a ring network. But instead of each computer being connected to the computer before and after it, there are multiple connections. A computer in a mesh network can be connected to 5 different computers. This is used in P2P transfer. This image should make it clear:
