question 9 (mandatory) (1 point)
listen
what is an operating system?
a language used for software development
a hardware device for controlling network traffic
software that manages hardware resources and provides services to applications
a type of virtualization tool

question 10 (mandatory) (1 point)
listen
which best describes the purpose of a distributed operating system?
to manage a group of networked computers as if they were a single system
to allow multiple users to share a single - user interface
to run legacy applications on modern hardware
to provide a graphical user interface for command - line tools

Explanation:

Question 9

• Option A: Programming languages (like Python, Java) are for software development, not operating systems. So A is wrong.
• Option B: Hardware for network traffic control is like routers, not an OS (which is software). So B is wrong.
• Option C: An operating system (e.g., Windows, Linux) manages hardware (CPU, memory, etc.) and provides services to apps (like file access, process management). This matches the definition.
• Option D: Virtualization tools (like VMware) are separate from OS; OS can support virtualization but isn't a virtualization tool. So D is wrong.

• Option A: A distributed operating system (e.g., for a cluster) manages multiple networked computers to act as a single system, sharing resources and tasks. This fits.
• Option B: Allowing multiple users to share an interface is about multi - user OS, not distributed (distributed is about multiple computers, not users on one). So B is wrong.
• Option C: Running legacy apps on modern hardware is done by compatibility layers or emulators, not distributed OS purpose. So C is wrong.
• Option D: Providing GUI for command - line tools is a utility or shell, not related to distributed OS purpose. So D is wrong.

Answer:

C. Software that manages hardware resources and provides services to applications
