However, it is ridiculous. Students who major in computer science, mathematics, physics. There is a good reason. A good example of a geometric series is the propagation of a computer worm. Consider the following hypothetical example in which. In this hypothetical example, at 2. But this example clearly shows the rapid growth of a geometric. Seen in this context, the criminal defense attorney's statement that. Actually, the defense attorney's statement is ludicrous. Even if one ignores the rapid growth of a geometric series. Chrisma Worm in Dec 1. Morris Worm in Nov 1. There is absolutely no need for another "experiment" of this kind. I put "experiment" in quotation marks, because the design and release. Other examples of specious defenses. Computer Crime. Early Examples. Brain virus. The first computer virus for Microsoft DOS was apparently written in 1.

TCP- IP mailing list via the Internet. A possible virus report: There may be a virus loose on the internet. Here is the gist of a message I got: I'm sorry. Here are some steps to prevent further transmission: [three terse suggestions for how to stop the worm omitted here]Hope this helps, but more, I hope it is a hoax. However, because the Internet was already clogged. Internet to avoid infection by the Morris Worm, the message did. Further, the anonymous source, and also the tentative tone. I hope it is a hoax.").
