Reviewing Internet clients and their uses

The answers you selected are indicated below, along with text that explains the correct answers.
1. Which search syntax would give you the exact URL if you were looking for a Web site for Oprah Winfrey?
Please select the best answer.
  A. +Oprah+Winfrey using Excite
  B. u: oprah winfrey using Yahoo
  C. "Oprah Winfrey" using Alta Vista
  D. Oprah AND Winfrey using Lycos
  The correct answer is B. Answer B is correct because the operative u: in Yahoo restricts searches to document URLs only. It is the only choice given here with that exclusivity. Thus, Answers A, C, and D can be excluded since although they would eventually yield the correct URL, they would find all documents containing the specified words not just the URL. NOTE: Check the advanced search option for all engines and directories to find which operator each uses to restrict a search to only a URL.

2. Which is not a benefit of FTP?
Please select the best answer.
  A. Moving files anonymously
  B. Avoiding email file size limitations
  C. Transmitting files in clear text
  D. Error checking
  The correct answer is C. A disadvantage of using FTP is that the files are transmitted in clear text. This means that the packets can be intercepted and username and password information can be obtained. Answers A, B, and D are incorrect because they all constitute legitimate benefits of using FTP and are of real advantage for business use.

3. What is the difference between a newsgroup and a discussion group?
Please select the best answer.
  A. Only members of a particular Web site can join a discussion group
  B. Newsgroups are registerd with USENET, discussion groups aren't
  C. Postings for discussion groups go to USENET
  D. There is no difference. The mean exactly the same thing
  Answer is B. A is wrong because anyone can visit a discussion group, even though its hosted by that Web site. C is wrong because posting for discussion groups go directly to the site hosting it, not USENET. D is wrong because discussion groups are privately hosted, while newsgroups are registered with USENET.

4. What are the two primary protocols used in Email?
Please select the best answer.
  A. HTTP and URL
  B. FTP and POP
  C. Telnet and MIME
  D. POP and SMTP
  The correct answer is D (Pop and SMTP). A is wrong because a URL's syntax includes the HTTP resource within it (HTTP://www.amazon.com). B is wrong because FTP is for file transfers from a fileserver and fileservers do not handle mail. C is wrong because Telnet is a terminal emulation protocol and has nothing to do with email.
