Internet Growth Charts
Believe it or not?
Let's start with the graph from the Welcome
to the Internet page.
Internet Domains

It shows the growth of Internet domains. Since we're
concerned about growth over time, if we run time along every x-axis, we'll be able to
compare the curves. When similar measures produce the same curve, the reliability of each
is strengthened.
The graph below measures Web servers. The term
"server" is commonly used to refer to the hardware as well as the software
package running on it. Commonly, there's a one-to-one relationship between them. The
hardware's no good without the software and you don't need more than one software package
per server.
Web Servers

Note The graph above doesn't cover as much
time as the other three because there was nothing to measure five years ago. So the curve
is a little flatter.
This subject is much more compex than I can cover here. If
you want more info on hosts and networks -- the graphs below -- please pursue it and share
your learning with the rest of us. I'm including them here only to demonstrate the same
curve and to increase the validity of each measure.
Internet Hosts

Online Networks

The colorful graph below from Netcraft doesn't have the same curve. It's measuring a
much shorter period of time over roughly the same height and width. It gives you an idea
about the relative strength of the companies that can afford the advertising and that
you'll read about in the print magazines. Apache is free so most of the information about
it is, too, advertising-free, that is, on the Web. Medaille, by the way, uses Netscape's
Fast Track, in the royal blue band.
Server Software

You can see where some of these other curves are
lagging behind according to Moore's Law. That's because the
chip speeds that it measures take a few years to get commercialized. It takes a little
while after that for the increasing power to get purchased and learned. If you want a
glimpse of the near future, catch the graphics on the Nintendo and Sega 64-bit game
machines that came to market late in 1997.

The grey-scale graphs came from Hobbes'
Internet World.
