director question....

#1

Hi,

Can someone help so l can leave Uni today, please please help

You switch on a computer and load (i.e. run) “Director”, making a note of how long it took to
start.

You then quit ‘Director’ and re-start it shortly afterwards. You notice that ‘Director’
starts considerably faster the second time (the experiment should work with any application
which takes some time to load).

This experiment is intended to apply to a computer where “Director” is already installed
locally, rather than timing the time it takes to load “Director” from a network…

  1. Why does “Director” load faster second time?

  2. How does the mechanism you describe in part (i) help speed up a computer?

  3. If a computer uses this <guess what I am thinking> mechanism to speed things up, why
    should you never “just switch a computer off – we used to” before shutting down the
    operating system first?

Well, I’m not going to do your homework for you…but I’ll give you a hint:

Think about the speed differance that exists between loading a file straight from the hard drive to memory and loading something from a remote hard drive, across a network cable, and then to memory?
