The workings of RAID 5 Is there a situation in which RAID 5 would be more appropriate than the other options?
Suppose you have a 100GB database housed on a disk array that supports a transfer rate of 60MBps and a tape drive that supports 200GB cartridges with a transfer rate of 80MBps. How long will it take to back up the database? What is the transfer time if 2:1 compression is possible?
UNIX treats file directories in the same fashion as files; that is, both are defined by the same type of data structure, called an inode. As with files, directories include a nine-bit protection strong. If care is not taken, this can create access control problems. For example, consider a file with protection mode 644(octal) contained in a directory with protection mode 730. How might the file be compromised in this case? What can we do to stop this vulnerability without changing the protection mode 730 for the directory?
Consider a RAID-5 system. Suppose a SQL query reads and updates just one tuple (and, by design, that tuple fits in one disk block). Assuming there are no database data in main memory, list the disk reads and writes that must occur to complete the operation fully.

Answer it True or False only. No explanation. Thanks 1. Interruption is an attack on availability e.g. destruction of piece of hardware, cutting of a communication line or disabling of file management system. 2. Cryptography is the study of principles and methods of transforming an unintelligible message back into an intelligible message without knowledge of the key. 3. A block cipher processes the input and block of elements at a time, producing output block for each input block. 4. An unauthorized party not only gains access to but tampers with an asset is referred to as fabrication. 5. Passive attacks are in the nature of eavesdropping on, or monitoring of, transmissions. The goal of the opponent is to obtain information that is being transmitted.
A processor that can decode encrypted data and system instructions, and then execute the instructions on the decoded data and system instructions, has been suggested. Encryption will then be performed by the CPU. Using a CPU this way has what advantages? Is there a need for a certain CPU architecture?
