| QUESTIONS WITH PASSED SOLUTIONS.
Which limitation can make it challenging for users to tailor the operating
system to their exact requirements? Answer - Inflexibility in customization
How can the complexity of modern operating systems impact user experience?
Answer - By causing user errors and misconfigurations
Which capability does an operating system have in terms of multitasking?
Answer - To enable the perception of simultaneous program execution by
managing system resources
How does the command interpreter in UNIX systems execute the command to
delete a file? Answer - It loads rm into memory and executes it with the file as
a parameter.
What does it mean for a kernel to be loosely coupled? Answer - The kernel
components are separate and independent.
How does the operating system handle process synchronization to ensure data
integrity among concurrent processes? Answer - Through locking mechanisms
like acquire_lock() and release_lock()
Which components are included in the execution state of a process? Answer -
Register contents, program counter, stack, and heap
, What is the purpose of the Thread Control Block (TCB) in operating systems?
Answer - Managing execution and context switching
How do multicore systems enhance performance compared to single-core
systems? Answer - By executing individual threads assigned to separate cores
What does the dining philosophers problem illustrate? Answer - The
challenges of resource allocation
Which role do monitors play in addressing the critical-section problem in
process synchronization? Answer - Ensuring orderly access to shared resources
How do race conditions occur in the context of process synchronization?
Answer - When processes rely on timing and execution order
What is a non-preemptive scheduling method? Answer - A method where a
thread retains a core until it terminates or enters the waiting state
What is the effect of a very large time quantum in round-robin scheduling?
Answer - It behaves like first-come, first-served (FCFS) scheduling.
In round-robin scheduling, how is the ready queue treated? Answer - As a
circular queue
A system administrator is examining a resource-allocation graph to understand
how processes and resources interact in a multi-tasking environment. The
graph includes various points that represent the system's components.
