Like all computers, laptops have a central brain called a microprocessor, which performs all of the operations of the computer.
The microprocessor:
- has a set of internal instructions stored in memory, and can access memory for its own use while working.
- can receive instructions or data from you through a keyboard in combination with another device (mouse, touchpad, trackball, trackstick).
- can receive and store data through several data storage devices (hard drive, floppy drive, Zip drive, CD/DVD drive).
- can display data to you on computer monitors (cathode ray monitors, LCD displays).
- can send data to printers, modems, networks and wireless networks through various input/output ports.
- is powered by AC power and/or batteries.
