SEARCH ENGINE
“Internet search engines are special sites on the
Web that are designed to help people find
information stored on other sites.”
We can search any information by use of search
engines. There are thousands of different search
engines to help people navigate the Internet. These
include major commercial search engines—like
Yahoo!, Lycos, AltaVista, and Excite, as well as
many smaller, industry-specific directories. There
are even Meta searchers, which work by querying a
number of other search engines and processing the
results.

8. SEARCH ENGINE
 Meta Search Engine:
A metasearch engine is not technically a search
engine, but a web portal that combines web
search results for a keyword or phrase from
various search engines using its own algorithm. ...
Some examples of metasearch engines
are lxquick, Metager, Metacrawler, Yabado,
Dogpile, and Zoo.

OPTIMIZATION
 Search engine optimization (SEO) is the
process of improving the quality and quantity
of website traffic to a website or a web
page from search engines. SEO targets unpaid
traffic (known as natural or organic results)
rather than direct traffic or paid traffic. Unpaid
traffic may originate from different kinds of
searches, including image search, video
search, academic search, news search, and
industry-specific search engines.

12. SEARCH ENGINE
OPTIMIZATION
 As an Internet marketing strategy, SEO considers how
search engines work, the computer-
programmed algorithms that dictate search engine
behavior, what people search for, the actual search
terms or keywords typed into search engines, and which
search engines are preferred by their targeted audience.
SEO is performed because a website will receive more
visitors from a search engine when websites rank higher
on the search engine results page (SERP). These
visitors can then potentially be converted into customers

EMAIL
Electronic Mail (email) is a system which allows
users of a computer network to send messages to
each other. Users can usually:
 Send a message to another user, or group of
users.

mailbox.
It is not only typewritten messages that can be sent
using Electronic Mail. Pictures, music, videos, in

faster that the ordinary post. It is also very
