A notebook PC is a light, thin profile, web-enabled, portable personal computer. Notebooks are often referred to as laptops, and are designed to maximize functionality with portability and power management. Similar to a desktop computer, a notebook PC includes a display screen, a keyboard, a pointing device and speakers. To increase battery life and reduce weight, some notebooks do not include internal optical drives such as DVD/Blue-Ray players, but do include several ports from which external drives may be connected as needed.
