Yes and no. They are often connected to network controller cards. However, many do connect to USB sockets too. Most cable modems have cables for both types of sockets.

What is the purpose of a null modem cable?

A null modem is a cable connecting two serial ports with the input and outputs and device control lines crossed over, so the input pin on one port is connected to the output pin on the other, and so on. It is also called a 'cross-over cable'. A null modem allows two computers to be connected together using their serial ports without using modems (hence null modem). If you used a standard ('straight') serial cable, the two inputs would be connected together, and the two outputs, and so on, so the computers would not be able to communicate. Modems have their data and control pins reversed internally, so a 'straight' cable is used between a computer and a modem.

Can you use a cable modem and connect it to a DSL ethernet internet connection and an ethernet router at the same time?

No you can not. Cable modems use RF or Radio Frequency to transmit data, usually converting that RF frequency into fiber optic via a node. DSL or Digital Subscriber lines use electricity like a phone line. You could also say Cable modems use coaxial cable and DSL use telephone wire. The two modems are not interchangeable.
