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




A) It seldom functions correctly.
kt kt kt




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




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




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




Answer: B kt




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




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




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

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




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




A) Application programs kt




B) Operating system kt




C) Computer hardware kt




D) The CPU kt




Answer: A kt




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




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




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




programs to run .
kt kt kt kt

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




kt utilization?
A) PC operating systemkt kt




B) Handheld computer operating system kt kt kt




C) Mainframe operating system kt kt




D) Real-time operating system kt kt




Answer: C kt




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




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




jobs being processed simultaneously .
kt kt kt kt kt




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




A) Compiler
B) Application program kt




C) Text editor kt




D) Kernel

Answer: D kt




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




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




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




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




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




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




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




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




Answer: D kt




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




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




interrupt to the CPU to get its attention .
