101. Multiprogramming of the computer system increases...
Correct! Multiprogramming ensures that the CPU always has something to execute, thereby increasing CPU utilization (efficiency).
102. Another type of multiple-CPU system is the...
Correct! Like multiprocessor systems, Clustered Systems gather together multiple CPUs (usually in separate nodes) to accomplish computational work.
103. Interrupt table of pointers having addresses for each interrupt is located at...
Correct! In many architectures, the Interrupt Vector Table (IVT) is stored in the first few hundred bytes of memory (Low Memory).
104. Example of open source operating system is...
Correct! Linux is the most famous example of a free and open-source OS. While some UNIX derivatives are open (like BSD), "UNIX" itself is a trademark often associated with proprietary systems.
105. Main memory of the computer system is known to be...
Correct! Main memory (RAM) is volatile, meaning it loses its contents when the power is turned off.
106. Controller of the computer system transfers data from device to...
Correct! Device controllers typically have local buffer storage where data is temporarily held before moving to main memory.
107. When many users access mainframes, this approach is called as...
Correct! Mainframes manage simultaneous access by allocating specific resources (CPU time, memory) to different users/terminals.
108. Accessing same data from storage of the computer system is provided by...
Correct! Parallel clusters allow multiple hosts to access the same shared storage simultaneously (e.g., Oracle RAC).
109. To start an I/O operation the device driver loads the appropriate register into is said to be...
Correct! The driver loads registers within the Device Controller to instruct it to start an operation.
110. Symmetric multiprocessing architecture of the computer system uses shared...
Correct! In SMP, processors share the same physical memory and the same system bus.
111. In asymmetric clustering other machines perform operations while one machine is in...
Correct! In this configuration, one machine is active while the other monitors it in "hot standby" mode, ready to take over if the active server fails.
112. The ability to continuously providing service proportional to the level of surviving hardware...
Correct! Graceful degradation means the system continues to run, but possibly slower or with fewer features, rather than crashing completely when hardware fails.
113. Secondary memory of the computer system is also called...
Correct! Secondary memory (Hard Disks, SSDs) is nonvolatile; it retains data permanently even without power.
114. Environment in which programs of the computer system are executed is called...
Correct! The OS provides the environment (services, resource management) in which programs are executed.
115. One word memory storage is the collection of...
Correct! In standard 32-bit architecture contexts, a "Word" is typically 4 bytes (32 bits). (Note: In older 16-bit systems, it was 2 bytes).
116. Each user of the computer system that uses computer services has at least...
Correct! A user interacting with the system is running at least one program (typically the shell, GUI, or the application they are using).
117. Clusters of the computer system can be used more efficiently using...
Correct! Parallelization divides a task into smaller subtasks that can be processed simultaneously across the cluster nodes.
118. A properly designed operating system must ensure that an incorrect (or malicious) program cannot cause other programs to execute...
Correct! Memory protection ensures that one program cannot interfere with the execution flow or memory of another program.
119. Table of pointers for interrupt to be executed contains the...
Correct! The interrupt vector table contains the memory addresses (pointers) of the specific interrupt service routines.
120. The user view of the system depends upon the...
Correct! The "User View" is defined by the Interface (GUI, CLI) provided by the Operating System, which hides the hardware details.
