Abstract
Abstract A computer system has a plurality of workstations (10,20,30) interconnected by a network (40). Each workstation (10,20,30) has at least one server program (415,510,520,530) which processes user events input to the workstation (10,20,30) from suitable input means (210,220,230) and also controls the display (200,201,202) of the workstation (10,20,30). One or more of the workstations also contains a client program (430,600). The server program (415,510,520,530) of each workstation (10,20,30) transmits processed user events to the client program (430,600) which then processes them. The client program (430,600) may then control some (more than one) or all of the workstations (10,20,30) on the basis of user inputs to any one of the workstations (10,20,30). Thus, for example, the client program may be arranged to generate corresponding windows on the display (200,201,202) of each workstation (10,20,30), so that any of the workstations (10,20,30) may control the display (200,201,202). A priority order among users may be used to resolve conflicting instructions. In this way, a greater efficiency of use of shared resources can be achieved. Of course the sytem may also be operated with a one-to-one connection of a server program (415,510,520,530) and a client program (430,600).
