Solved in 3 steps
- Compare the cypher feedback mode with cypher block chaining for large file delivery.Which ratio is more efficient?Discuss the security concerns associated with object serialization. What measures can be taken to secure serialized data?1. Explain why must the number of I/O requests be minimized. 2. How can the total seek time be reduced? Explain in good detail, with great examples
- A PDMS is composed of a set of peers and two kinds of mappings: storage descriptions and peer mappings. True or false? A True B FalseIn what ways might linked-file defragmentation help?Question V .True or False for the following statements: a. Protecting only data in a database that contains only sensitive data is a fairly simple problem. b. In network architectures, a logical connection exists only in hardware. c. Ideally, security should not be implemented in every network layer. d. In network security, end-to-end encryption works at the logical layer. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line
- What role do "keep-alive" packets play in persistent database connections?Consider the following augmentation of a remote-file- access protocol. Each client maintains a name cache that caches translations from file names to corresponding file handles. What issues should we take into account in implementing the name cache?Do you agree that "there is no idea of client and server sides of a communication session" in a P2P file-sharing program? Both yes and no can be used to answer this question.
- Primitives of transport service assume asymmetry between the two end points during connection establishment, one end (server) executes LISTEN while the other end (client) executes CONNECT. However, in peer to peer applications such file sharing systems, e.g. BitTorrent, all end points are peers. There is no server or client functionality. How can transport service primitives may be used to build such peer to peer applications?3) Can we have a control connection without data transfer connection in FTP? Explain. Give a diagram to show the commands exchanged and data transfer connection activities for a FTP session that retrieves an audio file. (FTP Commands: PORT , USER, PASS, RETR, QUIT, TYPE-EBCDIC, STRUR, QUIT, STOR,RMD.)6. Would it be possible to execute encryption functions in parallel on CBC mode with multiple blocks of messages? How about Decryption? 7. Why Should the IV in CBC be protected?
