Question

A. Client virtualization
B. Software as a service
C. Sandboxing
D. Embedded software

Answer

B. Software as a service

Explanation

Software as a Service (SaaS) is a software licensing and delivery model in which software is licensed on a subscription basis and hosted centrally on a remote server. The software can be accessed by users using a thin client, usually through a web browser.

With SaaS, a provider licenses an application to customers as a service on demand, through a subscription or pay-as-you-go model. The software vendor hosts and maintains the servers, databases, and code that constitute an application. This allows users to run the application concurrently without the need for any local installation on their devices.

Some key characteristics of SaaS:

  • Managed from a central location
  • Hosted on a remote server and accessed over the internet
  • Users not responsible for hardware or software updates
  • Provider manages security, availability, and performance

SaaS is part of the larger category of cloud computing services, along with Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).

The other options are not correct:

  • Client virtualization involves hosting a desktop operating system within a virtual machine running on a centralized server.
  • Sandboxing is a security practice that isolates applications to prevent outside malware or untrusted software from accessing data within the sandboxed application.
  • Embedded software is specialized programming on a device’s nonvolatile memory, not related to concurrent access over a network.

Therefore, Software as a Service best describes installing an application on a server for multiple concurrent users without local installation.
