Operating Systems 700: True / False Terms in this set (44) True or False: The operating system is responsible for managing each and every piece of hardware and software within the computer system. True True or False: Real-time systems are typically used in environments where time constraints are flexible and can tolerate significant delays. False True or False: The Network Manager is a core component of all operating systems. False True or False: Operating systems have not evolved significantly in terms of their basic functions over the decades. False True or False: The User Interface in an operating system always consists of graphical elements like icons and windows. False True or False: All operating systems must include support for networking to be considered complete. False True or False: The first-fit memory allocation method organizes memory blocks by size. False True or False: Virtual memory allows a computer to handle larger jobs than its physical memory could accommodate by itself. True True or False: Demand paging only loads pages into memory when they are explicitly requested. True True or False: The FIFO (First-In, First-Out) page replacement policy always reduces the number of page faults as memory size increases. False True or False: Segmented memory allocation does not require memory blocks to be contiguous. True True or False: Virtual memory can only be implemented using paging and not segmentation. False True or False: In a segmented memory system, segments must be contiguous in physical memory. True True or False: Dynamic memory allocation can lead to external fragmentation. True True or False: The Process Scheduler is also known as the low-level scheduler. True True or False: The main goal of the Job Scheduler is to maximize CPU usage by running CPU-bound jobs consecutively. False True or False: Virtual devices are a combination of dedicated and shared devices. True True or False: The I/O traffic controller handles the actual transfer of data. False True or False: The USB host controller can handle up to 127 devices. True True or False: Dedicated devices can be allocated to multiple jobs at the same time. False True or False: DMA allows the CPU to be bypassed during data transfer. True True or False: Spooling is a technique that helps convert dedicated devices into shared devices. True True or False: The Device Manager does not need to manage USB controllers. False True or False: DMA operations increase CPU burden by requiring constant CPU involvement. False True or False: Virtual devices reduce the efficiency of the system. False True or False: The I/O device handler is responsible for monitoring the status of False Operating Systems 700: True / False True or False: Increasing the number of processors always results in proportional improvement in system performance. False True or False: Patch management is only necessary for security vulnerabilities. False True or False: The best system improvement is always to add more memory. False True or False: System performance can be effectively measured by user satisfaction alone. False True or False: UNIX was originally developed in assembly language, making it less portable False True or False: Android is based on the Linux kernel and shares many of its foundational features. True True or False: Windows operating system uses a microkernel architecture to manage system resources. False True or False: In UNIX, the process and user tables contain identical information for managing processes. False True or False: Android uses encryption to secure data both at rest and in transit. True True or False: UNIX-based systems do not support any form of data encryption. False True or False: Cloud storage changes the fundamental concepts of file management. False True or False: The File Manager cannot interact with the Device Manager. False True or False: Sequential file organization is most efficient for files frequently updated with new records. False True or False: Indexed sequential access is suitable for files that require both efficient sequential read and random access. True True or False: Packet switching sends data packets on a predefined path and order. False True or False: A hybrid network topology can integrate elements of both ring and star topologies. True True or False: In a ring network topology, data flows in both directions to enhance reliability. False True or False: Wireless Local Area Networks (WLANs) are inherently less secure than their wired counterparts due to the nature of their transmission medium. True
