With the rapid development of microprocessor technology, microcomputer became increasingly affordable, ushering in the age of personal computing.

Key Components of a Microcomputer
- Central Processing Unit (CPU): The “brain” of the microcomputer that performs calculations and processes data.
- Memory (RAM and ROM): Temporary storage (RAM) for active data and permanent storage (ROM) for essential instructions.
- Input/Output Devices: Keyboard, mouse, display screen, and other peripherals that allow interaction with the computer.
- Storage Devices: Hard drives, solid-state drives (SSD), and flash storage provide long-term data storage.
- Motherboard: The main circuit board that interconnects all the components and enables communication between them.
Evolution of Microcomputers
Microcomputer emerged in the 1970s, with the Altair 8800 being a notable development as the first commercially successful microcomputer kit. This marked the beginning of personal computing, as hobbyists could assemble their own computers. The launch of the Apple I and Apple II in the late 1970s and early 1980s further propelled microcomputer into the mainstream.
As microprocessors like the Intel 4004 and Intel 8080 evolved, microcomputer became more capable, compact, and affordable, fueling the rise of home computing and business applications.
