A laptop, also known as a notebook or a portable computer, is a personal computer designed for mobile use. Laptops have a built-in screen, keyboard, and trackpad or pointing stick, and they are powered by a rechargeable battery. Laptops are typically smaller and lighter than desktop computers, and they are often used by people who need to work or access information on the go.
Laptops offer a number of advantages over desktop computers. They are portable, so you can take them with you wherever you go. They are also relatively lightweight, so they are easy to carry around. Laptops are also more energy-efficient than desktop computers, and they often have longer battery life. This makes them ideal for use in places where there is no access to a power outlet, such as on an airplane or in a coffee shop.
