From the manual:

NAME
sed - stream editor for filtering and transforming text

SYNOPSIS
sed [OPTION]... {script-only-if-no-other-script} [input-file]...

DESCRIPTION
Sed is a stream editor. A stream editor is used to perform basic text
transformations on an input stream (a file or input from a pipeline).
While in some ways similar to an editor which permits scripted edits
(such as ed), sed works by making only one pass over the input(s), and
is consequently more efficient. But it is sed's ability to filter text
in a pipeline which particularly distinguishes it from other types of
editors.
