Multitasking
DR-DOS provides a full multitasking environment on Pentium, 486, or 386-based hardware. This is built into the memory management extensions provided in the operating system, and is accessible for standard un-aware applications when using the Task manager (Taskmgr) utility. Programs however can have direct access to create separate threads etc, via the extended Application Programming Interface.
DPMS - A memory manager that works on 286/386/486/Pentium-based PCs, allowing device drivers to reside outside of the regular DOS application area. Drivers or Terminate stay-resident applications can thereby avoid using valuable application memory.
