Which describes a Software-as-a-Service (SaaS) example?

• A. Microsoft Word installed on a local computer
• B. On-premises database server
• C. A web-based email service like Gmail
• D. A platform for developing apps

Answer: (C)

SaaS means software that is provided over the internet and managed by a vendor, so you don’t install or maintain it locally. A web-based email service like Gmail fits this description because you use it through a browser, while Google hosts the application, handles updates, security, and data storage, and you can access it from any device with internet access. This is different from software installed on a local computer, which requires you to buy, install, and maintain it yourself; or an on-premises database server, which is infrastructure you run and manage within your own organization. It’s also different from a platform for developing apps, which is about providing tools to build software (a platform as a service), rather than providing end-user software like email.
