'Point-and-shoot' is not an official camera designation the way terms like 'DSLR' or 'mirrorless' are. With that said, the term does have a generally accepted meaning in the photographic community: it's a camera with a fixed-lens that's easy to pick up and use. A fixed-lens camera is also known as a compact; all point-and-shoots are compacts, but not all compacts are point-and-shoots, as some are quite advanced (not to mention expensive) and designed for serious photographers.
