Q

Why might video card / video adapter manufacturers prefer not to use a PCI interface?

A

Alternatives like PCIe and AGP offer additional resources to the expansion card.

Given that AGP is a disappearing interface, this information applies more to PCIe

Q

What is the purpose of a null-modem serial cable?

A

Used to connect two PCs together without using a modem.

Instead of connecting a modem to each PC via a serial connection (like they used to do…) this simulates a modem by just flipping some pins to “fool” the computer into communicating as if there was a modem in-between.

I’d liken this to a serial cable version of a crossover cable, though the comparison isn’t perfect.
