UGC NET Questions (Paper – 1)

Software as a Service provides complete software applications to users over the internet, eliminating the need for installation and maintenance on local machines. Users typically subscribe to the service and access it through browsers or thin clients. The provider manages updates, security and infrastructure, allowing users to focus on using the application. Therefore, the description in the stem corresponds to SaaS.

Option A:
Option A, Platform as a Service, offers a development and deployment environment rather than ready to use applications, so users still build their own software on top of it.

Option B:
Option B, Infrastructure as a Service, supplies virtualised hardware resources like servers and storage, leaving operating systems and applications to be managed by the customer.

Option C:
Option C, Desktop as a Service, streams a full desktop environment to clients and is conceptually different from providing specific applications as standalone services.

Option D:
Option D is correct because SaaS is defined by delivering software functionality over the web with the provider handling all backend responsibilities, exactly as stated in the question.
