Netbook

Netbooks are laptops that are light-weight, economical, energy-efficient and especially suited for wireless communication and Internet access.^[21][22] Hence the name netbook (as "the device excels in web-based computing performance").^[23]

With primary focus given to web browsing and e-mailing, netbooks are intended to "rely heavily on the Internet for remote access to web-based applications"^[23] and are targeted increasingly at cloud computing users who rely on servers and require a less powerful client computer.^[24] A common distinguishing feature is the lack of optical disk (i.e. CD, DVD or BluRay) drives. While the devices range in size from below 5 inches^[25] to over 12,^[26] most are between 9 and 11 inches (280 mm) and weigh between 0.9–1.4 kg (2–3 pounds).^[23]

Netbooks are mostly sold with light-weight operating systems such as Linux, Windows XP and Windows 7 Starter edition.

Because they're very portable, Netbooks have a few disadvantages. Because the netbooks are thin, the first such products introduced to the market had their primary internal storage in the form of solid-state drives and not hard disks, which are essential to installing very many programs.
