What Does Microcomputer Mean?
A microcomputer is a computer with a central processing unit (CPU) as a microprocessor. Designed for individual use, a microcomputer is smaller than a mainframe or a minicomputer.
The term microcomputer is not as commonly used as it was during the 1970s-1980s. We now refer to microcomputers as, simply, computers, or personal computers (PC).
Techopedia Explains Microcomputer
A microcomputer's CPU includes random access memory (RAM), read-only memory (ROM) memory, input/output (I/O) ports, interconnecting wires and a motherboard.
In 1970, Hewlett-Packard (HP) manufactured and released a microcomputer as a calculator with varying levels of programmability, although the Datapoint 2200 by Computer Terminal Corporation (CTC) is credited as the first microcomputer. Intel’s x86 processor family can also be traced back to CTC’s release.
