There are, in general, many buffers in an Emacs session. At any time, one of them is designated as the "current buffer". This is the buffer in which most editing takes place, because most of the primitives for examining or changing text in a buffer operate implicitly on the current buffer. Normally the buffer that is displayed on the screen in the selected window is the current buffer, but this is not always so: a program can temporarily designate any buffer as current in order to operate on its contents, without changing what is displayed on the screen.

(Info-goto-node "(elisp)Current Buffer").
