Questions with verified answers
A company needs to determine when a computer experiences a microprocessor
interrupt that is the result of a division by zero.
Which operating system (OS) service should be used? Ans✓✓✓-Error detection
A company needs to ensure consistent performance by decreasing the density of
bits from inner tracks to outer tracks.
Which hard disk method should be used? Ans✓✓✓-Constant angular velocity
A company requires a computing environment that supports high-volume data
processing and the management of a large amount of storage.
Which computing environment should the company use? Ans✓✓✓-Mainframe
a computer or computer program that manages access to a centralized resource
or service in a network. Ans✓✓✓-Server
a fixed-size contiguous block of a logical address space identified by a single
number, the page number. Ans✓✓✓-page
a fixed-size contiguous block of physical memory identified by a single number,
the page frame number. Ans✓✓✓-page frame
, a large central computer used by large organizations. Ans✓✓✓-Mainframe
a network of independent computers interconnected via a communication
network. Ans✓✓✓-Distributed system (multi-computer)
A process is not attempting to enter the critical section (CS), but it is preventing
other processes from entering the CS.* Ans✓✓✓-Lockout
a system of multiple CPUs and memories interconnected by a fast network into a
single parallel computer. Ans✓✓✓-Multiprocessor
an array that keeps track of which pages of a given logical address space reside in
which page frames. Each page table entry corresponds to one page and contains
the number or the starting address of the frame containing the page. Ans✓✓✓-

wired or wireless connections. Ans✓✓✓-Sensor network
digital signature Ans✓✓✓-bit string that uses public-key cryptography to
undeniably link a document to the producer and guarantees that the document
has not been altered in any way.
How do threads differ from processes? Ans✓✓✓-Threads execute portions of a
program within a process.
