Algorithmic Trading ??
Algorithmic trading  involves splitting a trade into multiple orders in order to reduce visibility and market impact, but the decision to take the main trade might or might not be automated. A fund manager might decide that a particular stock looks attractive based on his/her fundamental analysis and then instruct his/her trading desk to buy a block of stock. The traders on the desk might well use trade execution algorithms to finesse the placement of this trade.
Automated trading  on the other hand involves a set of rules (a very simple example might be a pair of moving averages of different lengths crossing over) that when satisfied automatically trigger the placement of an order. A small, simple automated trade might be placed directly into the market, while a more substantial one might be handed to an execution algorithm for placement in small order slices so as to reduce market impact etc.
