Notebook computer, also known as "portable computer", is characterized by its compact body and is more portable than PC. Notebook computer, also known as laptop, PDA or laptop, is a small and portable personal computer, which usually weighs 1-3 kg. The current development trend is getting smaller and lighter, but stronger. In order to reduce the size, all notebook computers now use liquid crystal display (also known as LCD screen).

Besides keyboards, some of them are equipped with touch pads or pointing sticks as pointing devices. The main difference between notebook and PC is that it is easy to carry, and it has different requirements for motherboard, CPU, memory, graphics card and hard disk capacity. Although the body of the notebook is very light, its applicability is beyond doubt. In daily operations and basic business, entertainment and computing operations, laptops are fully competent.
