A bus is usually drawn in circuits as one thick line with wires going
into or out of both ends. In my experience, that is done with a bundle
of wires in a "loom," but a bus seems to be different. Is there a
simple explanation of a bus?

Too specific. A bus is simply a bunch of connections -A bus is usually drawn in circuits as one thick line with wires going

power/address/data - shared by more than one other device.
So CPU might have and address and a data bus to talk to RAM. an IEEE -
488 device would have both on it. A USB bus includes power, and so on.

The other respondents have provided good answers, but it might be
important to know the difference between a "bus" in computer terminology
and electrical wiring.
In electrical use, a bus is a connection point for a single voltage
level. For example, the ground bus in a circuit breaker panel is a solid metal bar with screw lugs for the individual ground wires coming from
the electrical outlets. Likewise, a bus can be at a high voltage: a 440
volt AC bus to supply voltage to multiple load centers.
I mention this only because getting the two definitions confused could
have seriously bad results.
