pad is a cloth
covered pad, usually made of foam

Modern mice don't damage the work surface much and track fine without a pad in most cases, but people still like to use them. Sometimes mousing is more comfortable on a pad; sometimes people like to make a statement with the design they choose to have on their pad.
