sed is the stream editor.

Generally used to search and replace some parameters, while its capability is enormous.

Eg. if you want to replace all a with b then

echo abca | sed 's/a/b/g'
bbcb

Sed is the stream line editior where u can do the editing on the fly.
The power provided by sed is enormous.

Grep is used simply for pattern matching in the files.

With sed u can write ur own grep Smilie

best reference is man for the OS u r using.
