Yes nelmed;
A switch from a how you use it is no different than a hub. It is what one might call just a little more intelligent hub. It has a table of mac addresses and only routes packets to the 1 pc with the mac address that they are intended for, and yes it will do exactly what you need it to do by acting as a repeater for those longer that 100m cable runs. Just get a basic one and you'll be fine, there is such a thing as a layer 3 switch also which is more akin to the way a router routes packets. If your only talking a couple of PC's way out in the warehouse or something and money is really thght then I do believe most hubs are functional as repeaters too. The difference is a hub just sends packets along to every PC it has connected to it regardless of the actual intended 1. I did learn about 2 types of hubs though, (active & passive), you want the active type to be used as repeater. They taught us that passive type does not even act as repeater, just passes all packets thru to all PC's. I think most all hubs you find out there though are the active type.

I would recommend a switch, even a cheap one, because "hubs" are not full duplex. Put one cable into the uplink port and the other cable into a standard port to use it as a repeater. 4 or 5 port 10/100 switches are under $50.

Yes and No. A Switch is a level 2 device. It only sees the NIC addresses and is not capable of using IP multiple hops. To chain switches together requires a multiple hop protocol like IPX/SPX.

I'm not talking about a managed switch - I'm talking about a simple cheap dumb 10/100 consumer grade switch. I chain them all the time.
