A "laptop" is a portable personal computer that includes a screen, keyboard, and battery, allowing it to be used in various locations. Unlike desktop computers, laptops are designed for convenience and mobility. They can be powered by rechargeable batteries and are lightweight enough to be carried easily.
The term "laptop" combines "lap," referring to the seating area of a person, and "top," indicating that it is designed to sit on one's lap. The word became popular in the 1980s as portable computers gained popularity.
