Resumen de Dataspaces in L3
Martin-Uwe Beyer, Dietmar Heinrichs, Jochen Liedtke
L3 is a new multitasking and multi user operting system running on 386 based computers. One basic idea of the system is the concept of Dataspace, which is strongly influenced by early multics ideas. Dataspace is the abstract data type modelling storage. The details of memory, disk etc. are hidden. Higher levels of L3 only use Dataspaces for holgding data, no matter whether program code, program data, messages, files and databases. Special advantages of dataspace are cheap (lazy) copyng and the checkpointing facility.
