A netbook is a marketing term used in the past for small, low-performance, legacy-free, and inexpensive laptop. While the name has fallen out of use, machines matching their description remain an important part of the market for laptops running Microsoft Windows; similarly, most lower-end Chromebooks run on hardware which would have been described as a Netbook when the term was current, and inexpensive tablets when used with an external keyboard could be regarded as netbooks.
