Personal Computers are made of 10 basic physical components called computer hardware: monitor, motherboard, CPU, RAM, Expansion Cards, Power Supply, Optical disc drive, Hard disc drive, keyboard, and mouse.
The motherboard is the main component inside the case and connects the rest of the parts of the computer, including the CPU, the RAM, the disc drives and any peripherals.
A CPU (Central Processing Unit) performs most of the calculations which enable the computer to function, AKA "the brain".
RAM (Random Access Memory) stores all running applications and the operating system.
Peripherals (which I've always thought of as anything that plugs in) fall into two categories: input and output devices. Some examples of input devices: keyboard, mouse, scanner, webcam, microphone. Output devices include: printers, speakers, headphones, and LCD monitor.
