1. Introduction
As always, the connection speed of dial-up
is limited by the bandwidth of phone
lines. But at the same time, the average
file size for Web content is getting
larger and larger. Most of people use
broadband connections that can handle a
bigger load, so so Web sites feel more
comfortable bulking up their pages.

2. High-speed Dial-up:
Acceleration Servers
When you search for a Web page on the
Internet, your request is routed though
your ISP to the Web. But high-speed dial-
up providers have come up with some pretty
clever ways to open up that bottleneck.
By loading special software into a server,
they turn it into what they call an
acceleration server. And by sandwiching
the acceleration server into the chain
between your dial-up connection and the
Web, they can speed up the process
considerably.

3. High-speed Dial-up: File
Compression
The key element of high-speed dial-up
Internet is file compression. Text and
other files that need to remain perfectly
intact during the compression process use
lossless compression. At this point, the
on-the-fly file compression utilized in
high-speed dial-up can't be added to the
file types specified above because of the
nature of the data. If the compression
software were to change even one character
in the encrypted transmission, that would
render the data unusable.

4. High-speed Dial-up: Filtering
and Caching
You can see how caching saves time by
avoiding unnecessary data transmission.
The most amazing thing about this tool is
that with the combination of server-side
caching and client-side caching. It uses
what it learns to streamline your
connection process as much as possible. So
the more you use it, the faster it gets.

5. High-speed Dial-up: The Bottom
Line
I would seem that a clever combination of
fairly straightforward technologies has
helped to overcome some of the speed bumps
of dial-up Internet. These advances serve
to lengthen the life of dial-up Internet
and provide an alternative for those who
are tired of standard dial-up but not
quite ready for the leap to broadband.

6. Summary
Learning about High-speed Dial-up
connections, I think that Internet which
we always use is improved faster and more
useful. I did not notice these things, but
I use this knowledge, I need more
carefully to use Internet.
