New Forms of
Communication That Will Transform Teaching and Learning
What
is the Internet?
The Internet is simply millions of groups of computers (Networks) from
all over the world that share information and are loosely connected together.
The early uses of the Internet include E-mail, File Transfer Protocol
(FTP), Bulletin Boards, Newsgroups, and Remote Computer Access (Telenet).
The most successful application of the Internet, thus far, seems to be
the World Wide Web (Web).
These millions of computers all speak two common languages called Transmission
Control Protocol and Internet Protocol (TCP/IP). TCP breaks down every
piece of data that is to be transmitted into smaller pieces, such as an
E-mail, or an audio file (sound). Think of the process as if you would
put a letter in an envelope. IP determines how to get the letter from
point A to point B and initiates the transmission (distributes the letter
from a central location). The routers (like post offices) then send the
letter from router to router (spot locations along the way) until the
information reaches its final destination. It's like the post office picking
up your letter at a central location and determining where it goes to.
Due to the fact that this global network is comprised of so many computers,
information has more than one thousand methods for getting information
from point A to point B. In some areas of the globe there are not clear
paths for information to follow. This results in a slow up. This is usually
the case when you send a message and the recipient doesn't receive it
until days later.
