Computer Concepts Module 2 Practice Exam

Which cloud service model provides software applications accessed over the internet?

Infrastructure as a Service (IaaS) Software as a Service (SaaS) Platform as a Service (PaaS) Backup as a Service (BaaS)

Correct Answer:

Software as a Service (SaaS)

Explanation:

Software as a Service is the model that provides software applications accessed over the internet. In this setup, the provider hosts the application, handles maintenance, security, and updates, and you use the software through a web browser or lightweight client without installing anything locally. You typically pay for what you use and can access the latest version from anywhere with internet access. This contrasts with infrastructure as a service, which focuses on virtualized computing resources like servers and storage; platform as a service, which offers a development environment and tools for building apps; and backup as a service, which centers on data backup and recovery rather than delivering full software applications.
