Computer Hardware Terms, Glossary and Dictionary
A notebook computer, also known as laptop computer, is a small mobile personal computer. Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity. Notebook computers are capable of many of the same tasks that desktop computers perform, although they are typically less powerful for the same price. Notebooks contain components that are similar to those in their desktop counterparts and perform the same functions but are miniaturized and optimized for mobile use and efficient power consumption.
