A laptop, also known as a notebook computer or simply a notebook, is a portable personal computer. It is called a laptop because it is small and lightweight enough to be carried around and used on your lap. Laptops are designed to be used while you are on the go, and they typically have a long battery life to allow you to work or play without having to be plugged in. Laptops have most of the same features as a desktop computer, including a display screen, a keyboard, a touchpad or pointing device, and speakers. They also come with a variety of ports and connectors to allow you to connect to other devices and peripherals. Laptops are available in a range of sizes, with different processors, storage, and memory options to suit different needs and budgets.
