NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

Once you have a prescription‚ you go to a glasses store‚ where you select your frames and place the order for your glasses. Once the glasses have been made‚ you return to the store for a fitting

FIndex: Local index file for set of merged small files. Phase 4: Uploading of files to HDFS: Both of the files‚ local index file and merged file are written to HDFS which avoid overhead involved in keeping the information at NameNode. NameNode keeps the information of merged file and index file only. File correlations are considered when storing the files to improve the access efficiency. Phase 5: File caching strategy: The caching strategy is used to cache local index file and correlated

sick with infections that normally wouldn’t affect them. AIDS is short for immune deficiency syndrome. It is the most advanced stage of HIV disease. - How does HIV spread? HIV is spread by an infected person to someone else when there is an exchange of semen‚ vaginal fluids or blood. This happens during sexual intercouse‚ through the sharing of needles for injection or from an infected pregnant mother to her child at or about the time of birth. - Can HIV be transmited by kissing? The virus

Rushing attacks send duplicate Route Request (RREQ) to the neighbor node. If Request RREQ is from the true source address‚ then the system is regular and begins to transmit data packets otherwise repeat the process. This process is illustrated in Fig 1. Check threshold value: Next check the packet delivery ratio‚ if packet delivery ratio drops to threshold then move to next step. The threshold value is calculated using dynamic threshold algorithm indicated in [3]. The source node randomly chooses

1. Triple DES Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm‚ which hackers eventually learned to defeat with relative ease. At one time‚ Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry. Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits‚ but experts would argue that 112-bits in key strength is more like it. Despite slowly being phased out‚ Triple DES still
