The answer is pretty straight forward but many people in the business
mix the 2 all the time, or maybe I am just wrong. :-)
Pen-Test - the sole purpose of a pen-test is to penetrate the
network/application. The client and the consultant should agree on a set
of goals, like gain access to HR database from outside, gain access to
the credit card database... The end result is a yes we got in and this
is how or no we didn't get in.
Assessment - An assessment aims to find all vulnerabilities on all host
(or a representative sample) on the target network. Generally no attempt
is made to exploit is vulnerabilities past identifying them.
An example - On an engagement I find a host vulnerable to the IIS
unicode bug. During an assessment I would note it and move on. During a
pen-test I would tftp netcat, get a shell, escalate to system and start
poking around looking for "good stuff".

It is heavily dependent on the clients environment. Most security firms
do not have the expertise in house to perform a web application review
so if your site has a complex web app. it will not be tested during a
pen-test. The sales guys would call that an application
pen-test/assessment and raise the rates :-).
Just a quick note on tools. Everyone uses Nessus/IIS/CyberCop during an
assessment. You have to see HOW your consultant uses them. Do they run
it and give you the report? Do they check for false pos/negs? Do they
use it as a final sweep to make sure they did miss anything?

That depends on what you are doing. I would say you could do an
automated network scan on a workstation in this time. A full vuln. scan
enumerating services and finding vulnerabilities on a single host would
not take that long.
