What computing environment allows multiple independent operating systems to be installed on one hardware platform and run simultaneously?

• A. Containerization
• B. Application virtualization
• C. Virtualization
• D. Serverless computing

Answer: (C)

Virtualization lets you run multiple independent operating systems on one hardware platform at the same time. It works by using a hypervisor to create and manage virtual machines, each with its own virtual hardware and its own full OS. This isolation and decoupling from the physical machine allow different OSes to operate concurrently without interfering with one another, while sharing the underlying hardware resources. Containerization, by contrast, runs applications inside isolated user-space instances that share the host OS kernel, so they don’t provide separate OS environments. Application virtualization focuses on isolating individual applications within a single OS, not on running multiple full OSes. Serverless computing isn’t about operating system instances at all; it’s about executing small code functions in response to events without managing servers.
