Power Distribution Unit: http://en.wikipedia.org/wiki/Power_distribution_unit

Power Strip: http://en.wikipedia.org/wiki/Power_strip

A power strip adds outlets. A Power distribution unit distributes higher voltage and current into lower current and voltage (EG a 30amp 220v feed into two 15amp 110v feeds). A remote power switch allows power cycling generally via a network connection.

Much like modern modems, routers, switches a single unit may contain features of all three.
