Software as a service
Explanation
Software as a service (SAAS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. SAAS is one of three main categories of cloud computing.

When programs are written in these highlevel languages, the programs will require another special program called compillers to carryout a translation from the highlevel language to a machine level (0s and 1s) which is the level that is executable by computers.
