... expanded at a phenomenal rate.
Hundreds,
then thousands, of colleges, research companies and georgia business web hosting government business business hosting greenwood hosting greenwood agencies
began to connect their computers to this worldwide Net. Some
enterprising hobbyists and companies unwilling to pay the high costs of
Internet access (or unable to meet stringent government business hosting corona regulations for
access) learned how to link their own systems to the Internet, even if
"only" for e-mail and conferences. Some of these systems began
offering access to the public. Now anybody with a computer and modem --
and persistence -- could tap into the world.
In the 1990s, the Net continues to grow at exponential rates.
georgia business web hosting Some
estimates are that the volume of messages transferred through the Net
grows 20 percent a month. In response, government and other users have
tried in recent years to expand the Net itself. Once, the main Net
"backbone" in the U.S. moved data at 56,000 bits per second. That proved
too slow for the ever increasing amounts of data being sent over it, and
in recent years the maximum speed was increased to 1.5 million and bridgewater business hosting then
45 million business hosting corona bits per second.
Even before the Net was able to reach that
latter speed, however, Net experts were already figuring out ways to pump
data at speeds of up to 2 billion bits per second -- fast enough to send
the entire Encyclopedia Britannica across the country in just one or two
seconds.
Another major change has been the development of commercial
services that provide internetworking services at speeds comparable to
those of the government system. In fact, by mid-1994, the U.S.
government will remove itself from any day-to-day control over the
workings of the Net, as regional and national providers continue to
expand.
1.6 business hosting greenwood HOW IT WORKS
The worldwide Net is actually a complex web of smaller regional
networks. To understand it, picture a modern road business hosting corona network of trans-
continental superhighways connecting large cities. From these large cities
come smaller freeways and parkways to link together small towns, whose
residents travel on slower, narrow residential ways.
The Net superhighway is the high-speed Internet. Connected to
this are computers that use a particular system of transferring data
at high speeds. In the U.S., the major Internet "backbone"
theoretically can move data at rates of 45 million bits per second
(compare this to the average home modem, which has a top speed of roughly
9,600 to 14,400 bits per second).
Connected to the backbone computers are smaller networks serving
particular geographic business hosting greenwood regions, which generally move data at speeds
around 1.5 million bits per second.
Feeding off these in turn are even smaller networks or individual
computers.
Unlike with commercial networks such as CompuServe or Prodigy, there
is no one business web hosting setubal central computer or computers running the Internet -- its
resources are to be found among thousands of individual computers. This
is both its greatest strength and its greatest weakness. The approach
means it is virtually impossible bridgewater business hosting for the entire Net to crash at once --
even if one computer shuts down, the rest of the network stays up. The
design also reduces the costs for an individual or o ... |
