What technology spawned the development of microcomputers?

The development of microcomputers was primarily spawned by advancements in semiconductor technology, particularly the invention of the microprocessor in the early 1970s. This miniaturization of computing components allowed for the integration of the CPU, memory, and input/output functions on a single chip, making computers smaller, more affordable, and accessible to individuals and small businesses. Additionally, the proliferation of integrated circuits and advancements in software development further facilitated the rise of microcomputers.
