If I've got 2 NIC's in each computer one on each computer @ 10/full and connecting VIA HUB, and the other two NIC's connecting to each other @ 100/full VIA Crossover Cable, if I were to bridge the connections would I be getting 110Mb/sec ? I'm just not to sure what bridging connections mean but am i right ?
When a computer uses a team of NICs to communicate with other device (be it a switch, or whatever), it is usually not called bridging. Adapter teaming seems to be a generic term I have heard.

When using adapter teaming, this usually requires the NICs to be communicating at the same speed/duplex. It also usually requires the system to be connected to a switch that has been configured to treat both Ethernet connections as a single "pipe."

You usually only see the capability on more expensive equipment, servers and the like. It's usually only the higher end equipment that can really take advantage of the higher bandwidth.
Using two connections between two devices for the purposes of added speed, load balancing and redundancy is called trunking.

When you set up bridging (per within WinXP) what you are doing is turing your computer into a hub or switch.

Also, it's impossible to have a HUB that will handle full-duplex operation. You'd need a switch or bridge for that :)

Actually, your turning your computer into a bridge :)

A bridge is a networking device that examines incomming traffic, and if the traffic is for a computer on the other NIC, it will send out that packet on the other NIC.
Hubs cannot use 100/full duplex. You can run them at 100/half duplex, but not 100/full duplex.

To run full duplex, you require a virutal circuit with only two hosts, which only a switch can provide.

If I remember correctly, there is no such thing as 10Mbit/full duplex. 10Mbit uses only 1 pair of wires for both send and recieve, whereas 100Mbit has 2 pairs, 1 for send and 1 for recieve (and thus it can go full duplex -- data in two directions).
