In simple words a technocrat is an expert in a particular field be it economics, science or of managerial or administrative nature.
A technocrat deals with the technical aspects of the department that he deals with. And the most important thing to remember is unlike a politician a technocrat's decision making is based upon his technical expertise (contrary to public opinion)
Shaukat Aziz is a good example, he was an Economist, thus held the ministry of Finance (before he was crowned with Premiership)
A system of Govt. based primarily of technocrats is a technocratic govt.
my 2 cents...
