ENGS 4
Technology of Cyberspace
Winter 2004
Thayer School of Engineering
Dartmouth College
Instructor: George Cybenko, x6-3843
gvc@dartmouth.edu
Assistant: Sharon Cooper (“Shay”), x6-3546
ENGS4 2004 Lecture 1
Two main threads of the course
• Basic grounding in the technology
underlying the Internet and the Web
(including emerging new communication and
computing technologies)
• How this technology is being used and
might be used to “Predict the Future”
(using information about the past and present to
help anticipate the future)
ENGS4 2004 Lecture 1
Logistics
• Typically, each class will be divided into two
parts – internet technology and “prediction
science” – with a short break in between
• Please ask questions about terminology and
content
• Guest lectures on selected topics
• Course TA – Scott Hazard
• Cybenko’s office hours – Tues and Thurs 12-2
and by appointment
• No textbooks…materials will be online or in the
library

Honor principle
• Students can discuss material and help
each other but…..
• All work submitted for personal credit must
be the work of the individual student.
• Acknowledge all sources used in
completing an assignment – students,
literature, etc.
• If in doubt, ask.

Layers of Technology of
Cyberspace
• Underlying physical communications media:
copper wire, optical fiber, electromagnetic waves
• Reliable and efficient communication protocols
• Scalable decentralized networking
• Digitization of content and content standards
(web, images, audio, video, etc)
• Search capabilities
• Computer programming for applications
• Security, privacy, anonymity technology

ENGS4 2004 Lecture 1
What are the major technologies for
predicting the future?
• Delphic:
– Soothsayers, oracles, etc
• Aristotelian:
– The future can be derived from rules based on empirical
observations of the past combined with classical logic
• Newtonian:
– The future state is a deterministic function of present and
past states
• Markovian:
– The future state is a probabilistic function of present and
past states
• Quantum Mechanical
ENGS4 2004 Lecture 1
We will explore how different
disciplines “predict the future”
• Analyze the approaches used in terms of
Aristotelian, Newtonian and Markovian
• The applications will be drawn from areas
that rely heavily on networked information
systems based on the internet
Medicine, public health, science, finance,
business, education, art, entertainment,
national security, etc.
