Welcome to the forums
In lay terms
, it is referring to a a rear cassette with 10 sprockets, with the smallest having 11 cogs and the largest having 28 cogs.
Here are some Shimano examples of more, showing each cog that makes up that particular cassette.
The largest number will be the easiest gear and the smallest the hardest, in terms of power required from the cyclist.
Another way to look at it is that at the same revolutions per minute, a 11 cog will produce more speed than a 28 cog and thus, require more power to do so.
