Laptop is usually called laptop or "laptop". It is a small portable personal computer with the shape of "flip", alphanumeric keyboard under the "flip", and thin LCD or LED computer screen on the laptop. Upper, you can open to use the computer. Laptops are easy to transport when folded, so they are suitable for mobile use. Although laptops are initially different from laptops, the former is larger and heavier than the latter, but as of 2014, there is usually no difference. Laptops are often used in a variety of situations, such as work, education, Internet surfing using websites such as youtube, and personal multimedia and home computers.

A portable computer combines the components, inputs, outputs, and functions of a desktop computer (including a display, mini speakers, keyboard, pointing devices (such as a touchpad or touchpad), processor, and memory). Most pre-2016 laptops also have an integrated webcam and built-in microphone. Some 2016 laptops have touch screens. Laptops can be powered by a built-in battery or by an external power supply from an AC adapter. Hardware specifications, such as processor speed and memory capacity, vary widely between types, manufacturers, models, and price points. Depending on the intended use, the design elements, shape factors, and construction between models can also vary significantly. Examples of laptop specialty models include rugged laptops for construction or military applications, as well as low-cost laptops, such as those from the one laptop per child organization, which have features such as solar charging and semi flexible components that most other companies do not have. Portable computers, later developed into modern portable computers, were initially considered to be a small market, mainly used in military, accounting or travel sales representatives and other professional fields. With the development of portable computers into modern portable computers, they have been widely used for various purposes.
