Abstract: The present invention concerns a method for exchanging information between processes, tasks or computer applications executed by different operating systems coexisting on the same computer or the same hardware platform. This method allows communication between at least two client processes executed at the same time in a hardware platform (10) comprising one or more processors and storage means, at least part of which constitutes an addressable memory area that can be used as a working memory. These client processes are executed in two different operating systems (respectively) that are not directly compatible with one another. The method is characterized in that these the client processes write or read or modify information called exchange data in at least one common part, of the addressable memory of the hardware platform. The common part comprises an exchange memory.
