NOTES

Security and Reliability:

A bigger problem them criminal activity on the computer is Glitches in soft wear and bugs.
some examples:
*Once in the county of LA, the system at a Medical Center broke down, and it really showed the doctors and others that they rely too much on the computers because they didn't know what to do.
* another was a mars space orbiter. Right before it was about to land, it burned out due to glitches from mixing up English and metric units.

* a glitch in the computer accidentally charged cellphone users 600$ a min. one user was charged $57,346!

*2003: Japanese air traffic control failed and they had to communicate BY PHONE!

*all flights got canceled one Christmas for Delta air lines b/c the computer couldn't handle the number of flights being delayed by the weather.

the most famous bug was known as the Y2K bug. it was thought that as soon as it became 2000, before the millennium computer programmers made software to change only the last 2 digits because the first 2 were always "19" but when it became "20" many computers became unstable. some even stocked up on food and water prepared for the worst in case the economy (ran by computers) collapsed.

1. it is impossible to get rid of ALL bugs.
2.dangerous bugs are hard to spot
3. the bigger the system the bigger the problems
