very noob question

I have done a few covered calls recently to just try them out and see it in action. Mainly very small plays that in hindsight never stood a chance but I only lost maybe 50 bucks.

Anyways, I am wondering what it exactly means, what the out comes are for this and if its even something one would go for in this particular scenario. When the strike you buy is (example) $100 and is worth say .45 and the strike you sell is $101 is worth .48.

Sorry if this is a bad question or if I'm not explaining myself well enough.

Thanks for any help in understanding.
