microcomputer - Computer Definition
Generally refers to a Windows PC or Mac, but it can refer to any kind of small computer. When the term was first introduced in the late 1970s, it meant a computer with a single microprocessor chip as its CPU, namely, the personal computer. Today, the CPU in every computer is a microprocessor, and the terms "desktop computer," "laptop computer" and "PC" have mostly replaced the word microcomputer.
