CS99I Meeting 2 Notes: Intellectual Property

Started by Gio Wiederhold, 16 January 2000.

Representation

Why Binary numbers? reliability through simplicity.
Other base systems: 10, 3, ...
Character sets: ASCII 7 bits = 128 characters - 33 for control.
In practice 8 bits = 256 choices, ASCII plus whatever someone wants.
Think: How would you handle Chinese?

Representations

What is the benefit of Binary Number representation. Counting with only two symbols {0, 1} .
What about 10 {0, .. , 9}?

What about 3 {-1,0,+1}?

Build characters to words or numbers; words or numbers to records or sentences; records or sentences to messages; messages to papers or books; papers or books to knowledge?

Advantages and Limits

Readability
Processability
Granularity
