A portable computer that carries out the same functions as a

desktop but in a compact version that

is light enough to carry around.

regular use in one location.

Similar to a laptop but even more

compact. The name comes from its small

size.

Designed mainly for wireless

communication via email, messaging and

access to the Internet.
