Definition of a Laptop Computer

Laptops, often referred to as notebooks, are lightweight and compact portable computers. They contain all the same components as desktop computers and have a built-in LCD screen, keyboard and mouse. Laptops run off of an internal rechargeable battery to allow for up to several hours of mobile use.

Function

Laptops were created to allow for on-the-go computer use. Their hardware is optimized to run off battery power, and the weight and dimensions allow for portability.

Identification

Laptops can be identified by their lids, which flip open, like a book, to display the screen.

Price Considerations

Because of their small size, laptop computers are more expensive than desktops with the same hardware specifications.

Types

Laptops can be categorized as an ultra-portable (less than 5 pounds), a netbook (intended for mobile Internet access), rugged (capable of withstanding extreme conditions) or desktop replacements (designed to match the specifications of a desktop).

Warning

Laptops are more prone to damage than desktops, and must be protected from drops, falls and liquid.
