  multimedia files, such as audio or video
  programs, over the Internet using syndication
  feeds, for playback on mobile devices and
  personal computers.

PODCASTING AS A TERM

  "iPod".
• The editors of the New Oxford American Dictionary
  declared "podcasting" the 2005 word of the year,
  defining the term as "a digital recording of a
  radio broadcast or similar program, made
  available on the Internet for downloading to a
  personal audio player"

THE HOST

• Though podcasters' web sites may also offer
  direct download or streaming of their content, a
  podcast is distinguished from other formats by
  its ability to be downloaded automatically using
  software capable of reading feeds like RSS or
  Atom.

COMPARISON OF DIFFERENT SEARCH ENGINES

• SPEED
• SEARCH RESULTS
• FEATURES

8
comparison based on result display speed

• Only google and yahoo display the time the search
  lasted.
• This feature is not supported in the other search
  engines. But, we could still get the time it
  takes them to search a key word from firefox .(it
  is displayed in the right bottom side of the
  firefox window.)
• accordingly, google has been found the fastest of
  all in conducting the search for the keyword
  podcasting in 0.06 seconds. (0.328seconds as the
  firefox window displayed.)
• Yahoo comes next in the speed, and altavista,
  alltheweb and msn follow, in descending orders.

9
COMPARISON BASED ON THE NUMBER OF SEARCH RESULTS

• From the five search engines that this
  presentation studied, altavista.com doesnt
  display the number of search results.
• Google with 53,200,000 results have come up as
  the greatest number of search result for the
  keyword, podcasting.
• yahoo (42,200,000), alltheweb(35,500,000) and
  msn(239,963) follow.

10
comparison based on language

• wikipedia has different articles in 229
  languages,
• from the search engines, msn and yahoo are in the
  leading list with 38 and 37 language system,
  respectively.
• altavista and alltheweb come next with 36
  languages and google has 35.

11
CONCLUSION

• At the fields one of the search engines has its
  limitations the others have advantage over it,
  just as the one with the strength will also have
  a weakness on other parts.
• Therefore, the things that we failed to get in
  one search engine will be on the other, the
  features the one failed to support will be found
  on the other. So we should not stick to only one
  search engine.

12

• wikipedia is a very good and accurate source with
  the most relevant and to-the-point search
  results.
• But yet it is not the best place we go to search
  for pictures of our keywords.

13

• THEREFORE, IF WE ARE USERS OF ONLY ONE SEARCH
  ENGINE, WE LOSE THE OPORTUNITY OF GETTING
  DIFFERENT FEATURES THAT DIFFERENT SITES COULD
  AFFORD.

• I THANK YOU FOR YOUR ATTENTION.
• (please note that the speed and the search
  results of the sites expressed in the
  presentation may vary based on different factors.)
