12. INTRODUCTION TO SEARCH
ENGINES
Search engine is a special information retrieval
program designed to find information on the
computer system especially.
These are special websites where you do not have
to shift through categories. You just have to type
what you’re looking for into the search engine and
it will display all the related links.
Popular search engines of this era include Google ,
Bing, Ask, Yahoo, Altavista, Infoseek, Excite etc.
13. HOW DO SEARCH ENGINES WORK?
• Through links, search engines’ automated robots, called “crawlers,” or
“spiders” can reach the many billions of interconnected documents.
• Once the engines find these pages, they next decipher the code from
them and store selected pieces in massive hard drives, to be recalled
later when needed for a search query. To accomplish the monumental
task of holding billions of pages that can be accessed in a fraction of a
second, the search engines have constructed datacenters all over the
world.
• These monstrous storage facilities hold thousands of machines
processing large quantities of information. After all, when a person
performs a search at any of the major engines, they demand results
instantaneously – even a 1 or 2 second delay can cause dissatisfaction,
so the engines work hard to provide answers as fast as possible.
14. FAMOUS SEARCH
ENGINES
Google: Being the most popular among all. Google is
widely used by all the masses.
Bing: Coming on number 2, Bing used to be quiet
famous before but with the gradual increase in the use
of google, it lost it’s significance as the top one.
Yahoo: Yahoo still manages to secure the rank number 3
with an estimated of 300 million monthly users.
Ask: It is not quite among the favorites but still
manages to be useful with an estimated of 245 million
monthly users worldwide.
AOL: The AOL search has been long quite forgotten but
still draws up fair 125 million monthly users worldwide.
Not bad.
