one has an A at the end and one has a B at the end.

It's usually CAT-5 or CAT-5e.
The older method was by firewire. Most commonly these days is by USB or using a crossover cable. A crossover cable is basically an Ethernet cable terminated to T568A standards on one end and T568B standards on the other end. For the end user, they make user-friendly software to help configure the connections as well.

Crossover Cable (T568A on one end, T568B on the other)
It's usually CAT-5 or CAT-5e.
When wiring one end of an Ethernet cable with T568A and the other end with T568B, the wire pairs that get switched are the orange and green pairs. This crossover arrangement is typically used to connect two networking devices directly without the need for a crossover cable.
Yes, a crimper can be used to create a patch cable for a 100BASE-T network. To do this, you'll need to use an appropriate Ethernet cable (typically Category 5e or better) and RJ-45 connectors. The crimper allows you to attach the connectors to the ends of the cable securely after arranging the individual wires according to the T568A or T568B wiring standards. This will ensure proper connectivity for your 100BASE-T network.

This is a cross-over cable. But specifically, the orange and green pairs are only affected with relation to pin changes.
To create a Crossover Cable, wire one connecter to the T568A Network Standard and wire the other connector to the T568B Network Standard, so the cable 'crosses over', A becomes B and visa versa.
