Expanding the NETWORK

[changky]

Hello.

I would like to know how I can expand my network here in my small office.

Our office has 4 floors, ONE computer per floor. So what I did is i got a 4-port switch to connect the 4 computers, one port per floor.

Just recently, I have acquired additional computers per floor. Now I have 3 computers per floor. How do I expand the ports I installed previously? Can I expand the ports without removing my current setup?

Thanks!
