Help with network

i am a newbie with networking.
i am trying to do a network at a mates office and i need some help with what to use, i have to use the best and cheapest products around
he gave me a diagram and told me to find the products to use.
some one please help me

 

I usually see through these things you see, the "do my homework for me" posts..

We get them ALOT, so please don't do this or you'll be banned. This is your first warning.

It's quite obvious that your friend has not asked you to do this, if he gave you that diagram he obviously would have more knowledge on the subject than the average IT literate user, so asking someone who knows nothing to do it is just plain thick.

I suggest you bother to "READ" things, there are search engines, and from those you can get what your looking for the only thing im gonna help you on is this:

www.google.co.uk

 

What's with all the token ring and 10base2? That's a fictional network if I've ever seen one. Do your own homework, will 'ya?
