Major applications
Capabilities and limitations of the technology
Concepts and terminology of the technology
Policy and social context

Premise
• Networked applications and computing will be
pervasive in your personal and especially your
professional life
• End-users can conceptualize better ways to use the
technology (and this is the only way to make
major progress), but
• To participate, you need a basic understanding of
the technology and how it can be used
Berkeley SIMS and COE

IS106 and E111
Goals
• Conceptualize and analyze realistic new
networked computing applications
• Work effectively with implementers to realize
those ideas
• Be able to track current and future industry
developments
• Understand related policy and social issues

IS106 and E111
Goals (con’t)
• This course emphasizes concepts (habits of
the mind)
• It is not a skills course
– Future added laboratory is likely

IS106 and E111
Goals (con’t)
• If this is your first course on computing:
– You will develop a good idea of where to go
next
• If this is your only course on computing:
– You will be well positioned to follow and
understand developments for some time

IS106 and E111
Limitations
• Survey course, broad set of topics like Econ 101
• Modern approach, but
– Most deployed applications are legacy
– Today’s modern approach is tomorrow’s legacy
• Broad coverage requires simplification and
abstraction of many issues
– Programming not emphasized
– “The devil is in the details”
Berkeley SIMS and COE
8
IS106 and E111
Limitations (con’t)
• “Alphabet soup” of acronyms avoided
– But you should develop the background to
“slurp the soup” if you want
• Narrowed choice of technical topics:
relevance from an application perspective

In class
• Rely on your having read notes in advance,
so class can focus on:
–
–
–
–
Buttress most challenging concepts
Answer your questions
Discussion of controversial issues
In-class mini-projects
Berkeley SIMS and COE
13
IS106 and E111
Outside class
• Discussion forum
• Readings
• Explorations
– Experience in gaining topical knowledge
– Appreciate better those unfathomable details
• Homework
– Weekly
– Can be turned in by groups of one, two, or three
students (you will all get the same grade)
