Laptop
A laptop (also known as a notebook) is a personal computer designed for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (such as a touchpad), and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.
History[edit]
The history of laptops describes the efforts, primarily begun in the 1970s and 1980s, to build small, portable personal computers that combine the components, inputs, outputs and capabilities of a desktop computer in a small chassis.
Design[edit]
The design of laptops is centered around the idea of portability, and thus they are usually more compact than desktop computers.
Components[edit]
A laptop's main components are the same as those of a desktop computer, but they are integrated in a more compact, portable format.
Display[edit]
The display is the main interface between the user and the computer. The two main types of displays for laptops are LCD and LED display.
Keyboard[edit]
The keyboard is the main input device for the laptop. It is usually built into the same case as the display.
Pointing device[edit]
The pointing device, often a touchpad or trackpad, is used to control the position of the cursor on the screen.
Speakers[edit]
Speakers are used for audio output. They are usually built into the laptop.
Power supply[edit]
Laptops are powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.
