1. In what way is an operating system like a government?
w2 w2 w2 w2 w2 w2 w2 w2 w2




A) It seldom functions correctly.
w2 w2 w2




B) It creates an environment within which other programs can do useful work.
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




C) It performs most useful functions by itself.
w2 w2 w2 w2 w2 w2




D) It is always concerned primarily with the individual's needs.
w2 w2 w2 w2 w2 w2 w2 w2




Answer: B w2




Explanation: Just as a government creates an environment for citizens to live and work,
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




an OS provides an environment for application programs to execute and do useful work.
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




It doesn't perform useful work itself but facilitates it .

2. Which of the following components of a computer system defines the ways to
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




w2 use system resources to solve computing problems?
w2 w2 w2 w2 w2 w2




A) Application programs w2




B) Operating system w2




C) Computer hardware w2




D) The CPU w2




Answer: A w2




Explanation: Application programs, such as word processors, compilers, and databases,
w2 w2 w2 w2 w2 w2 w2 w2 w2




define how system resources are used to solve users' computing problems. The
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




operating system simply manages the resources and provides the foundation for these
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




programs to run .

, 3. Which type of operating system is designed primarily to maximize resource
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




w2 utilization?
A) PC operating system
w2 w2




B) Handheld computer operating system w2 w2 w2




C) Mainframe operating system w2 w2




D) Real-time operating system w2 w2




Answer: C w2




Explanation: Mainframe operating systems are designed to maximize utilization of all
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




system resources (CPU, memory, I/O) by carefully managing and scheduling the many
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




jobs being processed simultaneously .
w2 w2 w2 w2 w2




4. Which of the following programs runs on the computer at all times?
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




A) Compiler
B) Application program w2




C) Text editor w2




D) Kernel

Answer: D w2




Explanation: The kernel is the core component of the operating system and is the only
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




program that runs continuously on the computer. All other programs (like compilers or
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




editors) are system or application programs that run only when needed .
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




5. Which of the following events will trigger an interrupt?
w2 w2 w2 w2 w2 w2 w2 w2




A) A system call from a user program
w2 w2 w2 w2 w2 w2




B) The CPU executing a no-operation instruction
w2 w2 w2 w2 w2




C) A user logging out of the system
w2 w2 w2 w2 w2 w2




D) I/O completion from a hardware device
w2 w2 w2 w2 w2




Answer: D w2




Explanation: Interrupts are a key way hardware communicates with the CPU. An I/O
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




device, like a disk or keyboard, signals the completion of its operation by sending an
w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2 w2




interrupt to the CPU to get its attention .
