Introduction
The Internet is a global network of computers which allows people to exchange data worldwide
instantaneously.
This simple sentence is the most accurate way to summarize the definition of "Internet,"
but it does not do justice to the phenomenal technology behind the Internet. The Internet
spreads across all seven continents and includes computers that range from
35 year-old mainframes to modern home PCs to handheld devices. These computers
connect to the Internet via a tremendous array of communications mediums including phone lines,
coaxial television cable, fiber optic cable, serial lines, short-range (in-building) wireless
signals and long-range (cellular) wireless signals. Even with all this variance, the technology of
the Internet allows a 10-ounce handheld computer to exchange data with a room-sized mainframe from
the 1970's.
This Web site has been developed to provide a simple, "layman's" explanation of the unifying
technology of the Internet.
