SCRIPT UPDATED 2026 TESTED SOLUTIONS
⫸ Kernel Answer: The core program of an operating system that
controls hardware and software communication.
⫸ Resource Allocator Answer: The role of the operating system to
manage resources like CPU, memory, and I/O devices.
⫸ Control Program Answer: The function of the operating system that
controls the execution of programs to ensure correct usage and prevent
errors.
⫸ Multiprocessor Systems Answer: Systems that use multiple
processors to improve performance and reliability.
⫸ Symmetric Multiprocessing (SMP) Answer: A system where all
processors share the same tasks and memory, each processor can execute
all tasks.
⫸ Asymmetric Multiprocessing Answer: A system where each
processor is assigned a specific task, and one processor manages others.
, ⫸ Clustered Systems Answer: Systems where multiple computers work
together to provide higher performance or reliability.
⫸ Multiprogramming Answer: The technique where the OS runs
multiple programs by switching between them, optimizing CPU and I/O
device usage.
⫸ Multitasking Answer: The OS switches between task frequently,
giving users the illusion that they have exclusive use of the system.
⫸ Dual-Mode Operation Answer: The OS runs in two modes: user
mode (for user programs) and kernel mode (for system-level operations).
⫸ System Call Answer: A mechanism for a user program to request
services from the operating system.
⫸ Interrupts Answer: A mechanism that allows a program to request
CPU attention for immediate processing, often used in system calls.
⫸ Resource Management Answer: The OS's role in managing resources
like CPU, memory, I/O devices, and file storage.
⫸ Process Answer: A program in execution, which requires resources
like CPU time, memory, and I/O.
