Microcomputer Components in Computer Fundamentals


The five key parts of a Computer are:
1. Processor (also called the central processing unit or CPU)
2. Memory
3. Input / Output Devices
4. Disk Storage and
5. Programs

Before the advent of integrated circuits, individual portions of computer were housed on separate boards or even in separate units made up of many boards. Today the majority of the circuits of the microcomputer are housed on a single printed circuit called the system board or motherboard.

The usual components on the motherboard include the main processor and its support circuits, memory, I/O interface and a bus system which enables the CPU to talk to other components that are not integrated with the motherboard.
The processor is the brain of the microcomputer. It executes instructions and programs. The processor performs arithmetic and simple logical operations.
