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

3. Problem Formulation As it is evident from the related work discussed in the section 2‚ when small files are stored on HDFS‚ disk utilization is not a bottleneck. In general‚ small file problem occurs when memory of NameNode is highly consumed by the metadata and BlockMap of huge numbers of files. NameNode stores file system metadata in main memory and the metadata of one file takes about 250 bytes of memory. For each block by default three replicas are created and its metadata takes about 368

- What are HIV and AIDS? HIV causes AIDS. HIV stands for human immunodeficiency virus. It breaks down the immune system (our body’s protection against disease). HIV causes people to become 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

Activity 1: 1. Did any solutes move through the 20 MWCO membrane? Why or Why not? 2. Did Na+Cl- move through the 50 MWCO membrane? Activity 2: 1. Are the solutes moving with or against their concentration gradient in facilitated diffusion? 2. What happened to the rate of facilitated diffusion when the number of carrier proteins was increased? 3. In the simulation you added Na+Cl- to test its effect on glucose diffusion. Explain why there was no effect. Activity 3: 1. Which membrane resulted
