Operating systems make it possible to do what?

• A. Install software applications
• B. Browse the Internet
• C. Run hardware diagnostics
• D. Shutdown the computer

Answer: (A)

Operating systems provide the platform that lets software be added to and run on a computer. They manage the hardware resources (like CPU time, memory, and storage), control access with permissions, and offer tools and interfaces that installers rely on. This infrastructure—file systems, libraries, and process management—lets a program be placed on the system, configured, and connected to the right resources so it can operate. Without this environment, you wouldn’t have a reliable way to install new applications. Browsing the Internet, running diagnostics, or shutting down are all possible with an OS, but the direct capability being tested here is the ability to install software applications.
