What is the best solution with the choice of equipment for creating a local network?

Question

Network administration

Hello! The task is to build a local network between three cabinets using a router and hubs. That is, a router should be at the head of everything, from which three twisted pairs go to three cabinets, in which there is one hub and 10 computers. All this in one building. Do not even ask why this is how you need to build a network.
Please help me choose the right router and hubs for the best value for money.

Answer 1

do not even ask why it is so
and so understandable that a negligent student gives an old teacher a lab or a term paper.
a stupid answer to a stupid task:
any three hubs with at least 12 ports, for 10 Mb / s half-duplex, for example, 16-port "SVEC FD916" (guess what the office is called now), the last hubs were 100 Mb / s half-duplex about 10 years ago.
In as a router, a computer (OS is not important) with three network cards.

Answer 2

Hubs have not been released for a long time.
how many computers are in each office?
can you draw a simple diagram? and then from the words it is difficult to understand what is needed.
as I understand it, the gateway is needed to distribute the Internet? but you didn't mention it in your question.

Answer 3

[2] I built a similar network at school, only there were 2 rooms and each with 15 computers, the main criterion there was this: minimal money and a normal network, the D-link DIR-100 router did an excellent job and also 2 D-link DES switches -1016A. See the router for yourself, it's better to take something of the same plan, but with wifi, at least D-link DIR-300.
