Disaster avoidance planning has been described as the steps involved
to prevent a complete site disaster.    Business continuity planning
has been described as the processes and procedures a company puts in
place so that mission-critical functions can continue during and after
a disaster.  Do you feel that there is a marked difference in these
two activities?  Which aspects of these should a company concentrate
its budget on in light of the potential affects on personnel, IT
infrastructure, and business transactions?  Be sure to address both of
the above questions in your response

Sure sounds like homework.
Do you want website links that would help YOU "address both of the
above questions in your response"?

Yes, it is homework! I would love a website that would help in any
capacity. Actually, I would love an answer about 2 hours ago!

Two bucks? here's what I'd tell you for 2 bucks -

I have never heard of Disaster Avoidance planning. You cannot plan to
avoid a disaster, typically disasters refer to flood, fire,
earthquake, etc.

Business Continuity planning or Disaster Recovery is a legitimate
process governed by a large volume of best practice standards.
