A laptop is a computer that is portable and is able to offer everything that a traditional desktop computer does, but in a single, portable casing. Laptop computers are also different from other computing devices as laptops can run on rechargeable batteries installed within the laptop’s casing. Unlike desktop computers, laptops can be easily transported to places such as coffee shops, airports, libraries and offices. A laptop may be physically smaller than a desktop computer but in terms of performance, many laptops today can perform to a very similar standard to the average desktop computer. Laptop computers support the same type of software applications, apps, and everything else that desktop computers do.
