A laptop or laptop computer, is a small, portable personal computer (PC) with a "clamshell" form factor, typically having a thin LCD or LED computer screen mounted on the inside of the upper lid of the clamshell and an alphanumeric keyboard on the inside of the lower lid. The clamshell is opened up to use the computer. Laptops are folded shut for transportation, and thus are suitable for mobile use. Its name comes from lap, as it was deemed to be placed on a person's lap when being used. Although originally there was a distinction between laptops and notebooks, as of 2014, there is often no longer any difference. Today, laptops are commonly used in a variety of settings, such as at work, in education, for playing games, web browsing, for personal multimedia, and general home computer use.

A desktop replacement computer (DTR) is a personal computer that provides the full capabilities of a desktop computer while remaining mobile. They are often larger, bulkier laptops or in some cases 2-in-1 PCs with a tablet-like form factor and interface.

Some use a limited range of desktop components to provide better performance at the expense of battery life. These are sometimes called desknotes, a blend of "desktop" and "notebook", though the term is also applied to desktop replacement computers in general.

A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers that helps reduce their operating temperature, which is normally used when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related discomfort. A cooling pad may house active or passive cooling methods and rests beneath the laptop. Active coolers move air or liquid to direct heat away from the laptop quickly, while passive methods may rely on thermally conductive materials or increasing passive airflow.
