A laptop, also known as a notebook computer, is a small, portable personal computer (PC) with a “clamshell” form factor, suitable for mobile use. Laptops are an intrinsic part of modern life, utilized for both personal and professional purposes. They typically have a screen on the inside of the upper lid and an alphanumeric keyboard on the inside of the lower lid.
Key Characteristics and Components
Portability
One of the primary advantages of laptops is their portability. They are designed to be compact and lightweight, making them ideal for users who need computing power on the move.
Components
