$ man 1 cat | head
 cat - concatenate files and print on the standard output
$ man 1 dd | head
 dd - convert and copy a file

dd can read and write a file in blocks thus speeding up the transfer
whereas cat relies on the underlying C library to do it I/O.

dd can also convert from ascii to ebcdic, and do quite a few
other things. the man page is illuminating.
