In a couple of sentences or less?  

Valves are voltage devices.  You can control a relatively 
large voltage with a small amount of voltage. 

Transistors are current devices.  You can control a relatively 
large current with a small amount of current. 

Depending upon how you setup the circuitry they either: 
1) operate in within a certain characteristic region 
   much like a mechanical lever. 
2) operate in another characteristic region much like a switch. 

Crack any good book to find out what's 
going on at the subatomic level.
