ordinary telephone copper wire as well as over other media. Home and
business users who install an ISDN adapter (in place of a telephone modem)
receive Web pages at up to 128 Kbps compared with the maximum 56 Kbps
rate of a modem connection.


0
DSL

(Dedicated Subscriber Lines) Uses sophisticated modulation schemes to
pack data onto copper wires.


0
T1/T3 lines

A dedicated phone connection. T3 are faster.


0
Cable

(for example: Cox) Cable modems are much faster than dial
-
up or DSL.
However, they require a network card and a cable modem in addition to a
subscription fee added to the cable bill.


0
Fiber Optic Cables
. Fiber
-
optic lines are strands of optically pure glass as thin
as a human hair that carry digital information over long distances.

Internet Searching


0
It is very important that you
narrow your search
as much as possible

when
working with the Internet.

0
If you are very vague when searching, your search results may bring back
hundreds or thousands of sites pertaining to that topic.

0
Search Engines
:

Internet sites designed to assist the user in locating
information about a particular topic. Once you enter a topic to search, these
sites will search the Internet for you and give you links to other sites about your
topic.

Narrowing a Search

0
Internet search engines operate on a system called
Boolean
operators
.

This is a term for
the use of AND, OR, and NOT, + and


in
searches.

0
When searching the Internet, you will type words that the search
engine will then look for.

Example:
sports car

The way that the search engine interprets the space between
the word
sports

and
car

determines what links will be
returned.

In some cases, the search engines interpret the space as the
word “
OR
”.


FYI
-
not on test

Narrowing a Search

0
Plus
(+) or AND:


Using the plus sign will change the Boolean operator
from “OR” to “AND”, allowing the user to narrow the search.

0
For example, if you wanted to search for the rules for a game of billiard you might
want to try
typing either of these. They should work the same.

+billiards +rules



billards

and rules

0
Some
engines do not require the (+) signs or (
-
) signs due to the advanced
programming.

0
When searching remember that it looks at the first word (top) and then adds the other
search words.

Narrowing a
Search

0
Minus
(
-
) or NOT
:

If you put a minus sign directly in front of a
word,
many search engines
will NOT retrieve documents containing
that word.

0
So if you search for

+billiards


equipment

supplies

billiards and not equipment and not supplies

0
It will list billiards
-
related
documents
as long as they do not
emphasize equipment
and supplies
.



Remember that when you are using + or


in
a search string,


Put a space before the + or
-
.



Do not put a space after the + or
-
.

+billiards

equipment

supplies



FYI
-

More Effective
Searching

0
Use more
descriptive, specific words

as opposed to general ones.

0
For example, a search for Lamborghini will return much more specific results than a
search for

sports +car


sports and car

0
Most
search engines are not
case sensitive
, so it is not important to capitalize
words in your search.

0
When searching for
phrases

, place the phrase in quotation marks.

“United Nations”




Remember that when you are using + or


in a search string,


Put a space before the + or

Do not put a space after the + or
