Which of these is not an antecedent of the cloud?

software as a service
utility computing
grid computing
desktop computing

The correct answer is D. desktop computing.

  • 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.
  • Utility computing is a type of cloud computing that provides access to computing resources on an as-needed basis.
  • Grid computing is a type of distributed computing that uses a network of computers to solve a single problem.
  • Desktop computing is a type of computing in which users interact with a computer through a desktop environment.

Desktop computing is not an antecedent of the cloud because it is a type of computing that is not based on the cloud. Desktop computing is a traditional type of computing in which users interact with a computer through a desktop environment. The cloud, on the other hand, is a type of computing that is based on the Internet. In the cloud, users can access applications and data from anywhere in the world.
