The needs of experimental high-energy physics for large-scale computing and data handling are explained in terms of the complexity of individual collisions and the need for high statistics to study quantum mechanical processes. The prevalence of university-dominated collaborations adds a requirement for high-performance wide-area networks. The data handling and computational needs of the different types of large experiment, now running or under construction, are evaluated. Software for experimental high-energy physics is reviewed briefly with particular attention to the success of packages written within the discipline. It is argued that workstations and graphics are important in ensuring that analysis codes are correct, and the worldwide networks which support the involvement of remote physicists are described. Computing and data handling are reviewed showing how workstations and RISC processors are rising in importance but have not supplanted traditional mainframe processing. Examples of computing systems constructed within high-energy physics are examined and evaluated.

Additional Information: © 1992 lOP Publishing Ltd. This review was received in April 1992. I would like to thank my many colleagues who have discussed their work with me and have thus knowingly or unknowingly contributed to the material presented in this review. I am particularly indebted to R Ball, F Fluckiger, E Jagel, J Knobloch, H Kowalski, K Mcfarlane, O Martin, U Martyn, H Renshall, D Underhill, C Youngman for supplying me with information and/or figures and to my wife Jane for help in preparing and checking the manuscript. My treatment of individual projects and achievements has been necessarily very limited. I recommend that any reader seeking a better understanding of HEP computing turn first to the proceedings of the series of international conferences on computing in high-energy physics (CHEP 1984 to CHEP 1991).
