The correct answer is D. All of the mentioned.
A platform is a foundation or basis upon which something else is built. In the context of software, a platform can be based on specific types of development languages, application frameworks, or other constructs. SaaS is the cloud-based equivalent of shrink-wrapped software. It is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. Software as a service (SaaS) may be succinctly described as software that is deployed on a hosted service.
Here is a more detailed explanation of each option:
- Option A: Platforms can be based on specific types of development languages, application frameworks, or other constructs. For example, the Java platform is based on the Java programming language, the Java Virtual Machine, and the Java Standard Library. The .NET platform is based on the C# programming language, the .NET Framework, and the .NET Standard Library.
- Option B: SaaS is the cloud-based equivalent of shrink-wrapped software. Shrink-wrapped software is software that is sold in a physical package, such as a CD or DVD. SaaS is software that is accessed over the Internet, and it is typically paid for on a subscription basis.
- Option C: Software as a service (SaaS) may be succinctly described as software that is deployed on a hosted service. A hosted service is a service that is provided by a third-party provider and that is accessed over the Internet. SaaS applications are typically hosted on servers that are owned and operated by the SaaS provider.
In conclusion, all of the mentioned statements are correct.
