This is one of the most exciting times in technology,
ever, and the Internet has the potential to change the way
that people work and play, in a way that few technological
areas have ever done before. It will soon become part of
the fabric of our life, in the same way that the motor car,
the telephone and the television have done in the past.
The greatest problem is that Internet technology is moving
so fast that it is difficult to keep up with it. Thus it
is important to understand the key underlying principles
of it, which allows everyone to learn new developments.
I have seen so many people who struggle with new technological
developments as they do not have a proper foundation in
the subject area. This book and the associated WWW site
will hopefully help provide this foundation.
The amount of transmitted information over networks increases
by a large factor every year (over the Internet, traffic
doubles every 100 days), and the demand for bandwidth seems
unlimited. Unfortunately there are many different types
of networks, from low-speed single computer connections,
to high-speed multiple computer networks. There are also
many different types of computer systems, there are different
protocols, and so on. It is an exciting area, but also a
difficult area to keep up-to-date with. Thus, one of the
main aims of this book is to cover many of the important
networking and distributed system areas, from networking
technologies to data encryption. It splits into ten main
areas, these are:
