OPERATING SYSTEM CONCEPTS
COMPREHENSIVE TEST 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
●● Symmetric Multiprocessing (SMP). Answer: Each processor
performs all the tasks within the OS; all are peers. Has multiple nodes
running applications, monitoring each other
●● bootstrap program. Answer: Typically stored in ROM or EPROM,
generally known as firmware, Initializes all aspects of system, Loads
operating system kernel and starts execution
●● Client. Answer: a software component on a computer that accesses
services from a network server
●● Server. Answer: a computer that plays one or more of several
important roles on a network. in all these role the server provides
services to other computers (clients)
●● P2P (peer-to-peer). Answer: does not distinguish clients and servers,
all nodese are considered peers. Can each act as client, server, or both.
●● CPU. Answer: Central Processing Unit, An integrated circuits that
performs the calculations, or processing, for a computer
, ●● CPU scheduling. Answer: controls the processes running
●● device driver. Answer: software that is added to an OS to control a
physical component (device).
●● DMA - Direct Memory Access,. Answer: A method that allows an
input/output (I/O) device to send or receive data directly to, or from the
main memory, bypassing the CPU to speed up memory operations. The
process is managed by a chip known as a DMA controller (DMAC)
●● escalation of privileges. Answer: allows user to change to effective
ID with more rights
●● fault tolerant. Answer: can suffer a failure of any single component
and still continue operation. It requires a mechanism to allow the failure
to be detected, diagnosed, and if possible, corrected.
●● firmware. Answer: software resident in integrated circuits
●● group identifiers. Answer: Allows set of users to be defined and
controls managed, then also associated with each process/file
