Data Encryption Standard In 1972‚ the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security‚ a subject then in its infancy. One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data during transmission and in storage. Prior to this NBS initiative‚ encryption had been largely the concern of military and intelligence organizations. The encryption algorithms‚ i.e.‚ the

Data Trappers‚ Inc. When examining whether or not B&T should be permitted to serve as the independent auditor of Data Trappers‚ Inc. (DTI)‚ we must first look at what it means to be an independent auditor.

Data Interpretation and Short Essays B.1. Using the results from A.1‚ describe and comment on the differences in the mortality parameters (CDR and I-SDR) and patterns of the Black and White American female population. Please justify what are the possible reasons of its differences. Using the results from A1‚ we can see that there is the Black American Female Population has a lower CDR and a higher ISDR than the White American Female Population. As we know CDR does not refer to sub-groups that

.16 RESEARCH ANALYSIS LIST OF STATISTICAL TECHNIQUES There are various sampling techniques available for market research‚ but we selected the following for our analysis: 1. Chi-square – It is useful in analysing cross tabulations of the survey data. Since it can tell us whether there is a statistical difference between the segments in how they answered the question 2. Correlation – It can show whether and how strongly pairs of variables are related; mostly used with rating scales. 3. Cross
