To emphasis the point: A crowd in bleachers sitting down and watching the game
provides a static load. When an exciting play on the field happens and everyone
stands up at once, there is a dynamic load as the bleachers have to stand up to
the additional force of lifting all of the bodies from sitting to standing (or
worse, jumping and the eventual landing). Dynamic loads are generally more
challenging to analyze.

In computers, again, it's much easier to handle things statically, but there is
much less flexibility.

More concisely

But someone who is professional please confirm:

"Dynamic" refers to things that happen during execution / run-time of
the application.

"Static" is everything else.

This underscores the absolutely critical difference between run-time for a
program / application and any other kind of activity for that software.

Admittedly it runs slightly contrary to the common-sense intuition that
"dynamic" = something's happening and "static" = nothing's
happening. During compile-time and install-time, plainly, "something"
is happening. It seems as if Oracle is trying to exploit this, conflating the
common sense meaning with the actual technical meaning.

static vs. dynamic in computer science
Authored by: Anonymous on Monday, May 14 2012 @ 04:16 PM EDT
Here is a link to my comment from a few articles ago, describing the difference between a "static optimization" and a "dynamic optimization". At the end, I also mentioned the difference between "static linking" and "dynamic linking".

Those are both examples where "dynamic" means "at run-time" and "static" means "at compile time".

Here is another example:

Languages with static typing do their type-checking at compile time (before the program runs).
Languages with dynamic typing do their type-checking at run-time (while the program runs).
