It depends on whether you use MS-DOS or a better OS ;)
DOS was the last operating system which I know of which used temporary
files for pipes. Every other system uses in-memory FIFOs
(first-in-first-out).
BTW: your last example "type | sort | uniq" can be shortened to "type |
sort -u"
Hope this helps,
