This circuit is sometimes called "grounded-emitter configuration".  Note that this circuit can be realized with a bipolar transistor or fet.  The bipolar transistor has a lower drive voltage ( usually well under 2 volts ) the fet can easily need 10 volts of drive -- use a logic level fet to reduce the drive voltage.

Some characteristics:
 
 
*Useful ( with simple circuits and common components ) for currents from a max of a few amps and voltages of 10's of volts.
 
*Can be very fast, into the Mega Hz.
 
*Can be very cheap at the low end.
 
*Small, simple.
 
*Some integrated circuit drivers like the  are basically multiple transistor low side switches.
