In a modern operating system, if a process wishes to use a device: A process can directly access the device to instruct it accordingly without switching to Kernel mode.[1]  In passing data to a device, the data from the process is typically first copied to a buffer that can be read by the OS in Kernel mode. [2]  Processes access data from a character (serial) device in fixed-sized blocks of bytes.[3]  Processes transfer data to a block device as a stream of individual bits, one at a time.[4] 

Which of the following would result from doubling the block size in a multilevel indexed filesystem, assuming no other changes? Doubling of maximum file size.[1]  Decrease the average read/write time on spinning disks.[2]  Increased space efficiency / utilization.[3]  Doubling of maximum filesystem size.[4] 

Which of the following models is used to protect the confidentiality of data?

Which of the following would result from halving the block size in a multilevel indexed filesystem, assuming no other changes? Halving of maximum file size.[1]  Halving of maximum filesystem size.[2]  Decrease the average read/write time on spinning disks.[3]  Increased space efficiency / utilization (in general).[4] 

Select True or False for the following statements An access control matrix that consists of a large number of groups, and objects will take up more storage space than an access control list of the same number of groups, and objects.[1] A user at security level 2 using the Bell-Lapadula model can only read objects at level 2.[2] In asymmetric secret-key cryptography, the encryption key is always announced publicly.[3]

Which of the following are true of chained table allocation (e.g. FAT file system)? I. Files are allocated in fixed-sized blocks. [BL] II. All parts of the file are stored at contiguous addresses.  [CON] III. Chained table allocation (FAT) uses a table to track free disk space.[MA] IV. Uses index block entries to locate data. [IN]  

Select True or False for the following statements. The Short Term Scheduler is responsible for maintaining memory load.[1]  The Long Term Scheduler prevents Batch systems from being overloaded.[2]  The Medium Term Scheduler selects which process will be allocated to the CPU.[3]
