go - What is channel buffer size?

Question

I'm trying to create an asynchronous channel and I've been looking at http://golang.org/ref/spec#Making_slices_maps_and_channels.

c := make(chan int, 10)         // channel with a buffer size of 10

What does it mean that the buffer size is 10? What specifically does the buffer size represent/limit?
