2. 1.Introduction to How High-
speed Dial-up Works
The handshake protocol, as the
name implies, begins the
conversation that allows data to
be sent to and from your computer
using the Internet. There are
actually two separate handshakes
that occur in this process.

3. 2.High-speed Dial-up: Acceleration
Servers
The acceleration server uses a broadband
connection to quickly search the Internet
for the server that hosts the page you're
looking for. Once it finds that server, the
two machines start talking and exchanging
the information you need.

4. 3.High-speed Dial-up: File
Compression
The key element of high-speed dial-up
Internet is file compression. If you've read
How File Compression Works, then you
know that there are two types of file
compression: lossy and lossless.

5. 4.High-speed Dial-up: Filtering and
Caching
To combat this drag, high-speed dial-up
providers have bundled a pop-up blocker
into the software they send to subscribers.
This pop-up blocker is programmed to
recognize those lines of code that spell out
the ad parameters.

6. 5.High-speed Dial-up: The Bottom
Line
It would seem that a clever combination of
fairly straightforward technologies has
helped to overcome some of the speed
bumps of dial-up Internet.
