<p>In the system, computer programs are distributed by a host system (100) to a plurality target systems (200, 201, 202). The host system stores a plurality of different computer programs in a first storage means (110). Selection means (120) are used to selecting a computer program from the stored computer programs. Transmission means (130) simultaneously transmit the selected computer program to a plurality of target systems via a data communication medium. Reception means (310) in the target system receive a computer program transmitted via the data communication medium. Storing means (320) automatically store a received computer program in second storage means (330). The target system uses execution means (340) to execute a user-selected computer program stored in the second storage means (330). Preferably, each target system is assigned a unique target identifier. Before transmitting a selected computer program, the transmission means transmit activation information incorporating target identifiers. The reception means receive the activation information and only receive a following computer program if the activation information incorporates a target identifier which matches the assigned target identifier uniquely identifying the target system.</p> |
