I understand this is a very novice question to ask but I just want to make sure I have a firm grasp on the concept(s)
Resolution is how many pixels displayed on a screen by height x width.
How does this relate to pixel per inch(es). I'm assuming bigger monitors have more ppi.

You are correct in saying that resolution is screen width x height (in pixels).
Pixels Per Inch (PPI), will actually get smaller as your screen gets bigger. PPI is a measure of pixel density. As the area a screen covers gets smaller, the pixels are more densely packed and so the PPI goes up.

Which can make the image sharper? – Joseph – 2013-12-17T16:26:42.357
Typically, a higher density (higher res or smaller screen) will look better. – heavyd – 2013-12-17T16:33:38.200
Last question: how is PPI calculated – Joseph – 2013-12-17T16:47:39.237
For screens, the Wikipedia entry says it is the diagonal resolution/diagonal size

Other things being equal, bigger monitors will have less pixels per inch. A bigger monitor means more inches, so fewer pixels per inch. – David Schwartz – 2016-07-22T16:57:55.223
