What is a paragraph (when accessing memory)

Question

I feel stupid when you ask something that sounds like it should be so easy to find, but as you might have guessed, finding a paragraph gives a lot of results that have nothing to do with what I want to know.

I have been studying assembly in the last few days (writing a tiny bootloader, a bit of a practice), and I have seen several references to pieces of memory called a paragraph. I have a distant memory that a paragraph is two words, but I'm really not sure. What is a paragraph and what is its meaning?

Answer 1

The paragraph is 16 bytes. This is relevant primarily (if not exclusively) in real x86 mode, where is the distance between the two addresses that you get when you increase / decrease the segment register by one.
