Data Acquistion systems in HEP experiments use a wide spectrum of computers to cope with two major problems: high event rates and a large data volume. They do this by using special fast trigger processors at the source to reduce the event rate by several orders of magnitude. The next stage of a data acquisition system consists of a network of fast but conventional microprocessors which are embedded in high speed bus systems where data is still further reduced, filtered and merged. In the final stage complete events are farmed out to a another collection of processors, which reconstruct the events and perhaps achieve a further event rejection by a small factor, prior to recording onto magnetic tape.
