2. • A laptop computer is a personal computer for
mobile use. A laptop integrates most of the typical
components of a desktop computer, including a
display, a keyboard touchpad and speakers into a
single unit. A laptop is powered by mains
electricity via an AC adapter, and can be used
away from an outlet using a rechargeable battery.
Laptops are also sometimes called notebook
computers or notebooks.
