The challenge of storing and managing unstructured data comes from the fact that it is unstructured. It is inherently resistant to search, classification, and organization. This makes it much harder to turn the data into information. Some of the tools with which unstructured data can be utilized include data mining, pattern analysis, and meta-data creation/analysis. 2.

7. Why do global variables make a program difficult to debug? Global variables make a program difficult to debug because any statement in a program file can change the value of a global variable. If you find that the wrong value is being stored in a global variable, you have to track down every statement that accesses it to determine where the bad value is coming from.

Now that computers have become main stream, tape recording and writing down information by hand are soon to become obsolete. According to the Merriam-Webster Dictionary, the term memory, both human memory and computer memory, is defined as, “the store of things learned and retained from an organism's activity or experience as evidenced by modification of structure or behavior or by recall and recognition” (“Memory”). Computer memory and human memory have numerous parallels between one another, but the two are so remarkably different in most aspects that they are not even comparable to one another. Some of the main, most extreme differences include how the memory is constructed, how it is stored, its purpose, and the anatomy of the human memory compared to that of a computer’s memory. Since the beginning of science, the human memory has been a hot topic.
