    Maybe I'm being too simple, but you could have the router connected to a switch. All of the computers would connect to the switch. Router is the only device on the network handing out ip's.

    That's the wired option. Wireless router and wireless NIC's, but same infrastructure.

    I suppose in this pic the box on top is the switch. Router would be also connected to it.

    I've got a switch on the network, its a small office network, so I could say that I connect the router to the switch, and would all the workstations have a wired connection to the router ?

    This network only exists on paper, we had to design a network and explain how it all works.

    Pretty simple -
    http://en.wikipedia.org/wiki/Network_address_translation
    http://www.howstuffworks.com/nat.htm

    How specific do you want to be?
    DHCP process, ARP, (default) IP Routing, NAT, PAT etc....

    I just need about half to 3 quarters of a page, I have to explain how it connects to the internet, what hardware and security is there at that point aswell ?

    Do the research.
    You can list NAT as a security feature - don't over complicate it.

    So if I was to say the router is connected to the hub, and all the workstations are connected to the router and hub, that would give internet access to all workstations on the network ?

    Read your college notes.
    Google routing, switching, NAT/PAT, Default Gateway, IP addressing, Small Network Design etc.

    Do up your assignment and post it up and people can comment on it and make suggestions.

    Also, can you post up the full details/requirements of the assignment?

    If a router has dhcp on, and the pc's are set to dhcp, and both the router and the pc's are connected to the hub/switch, then yes, that's all you need.

    Look up the various terms we are using, none of this is rocket science, and are at the basic level of networking.

    Have a look at something like this.
