a river in the northwestern part of the Federal Republic of Germany. The Ems is 371 km long and drains an area of 12,500 sq km. It rises on the southwestern slopes of the Teutoburg Forest and flows over the North German Lowland, emptying into the Dollart of the North Sea and forming an estuary 20 km long. The mean flow rate is 72 cu m per sec; the water level is higher in winter and spring. The river, which has been straightened and canalized in places, is navigable to the city of Greven. The Ems is connected by canals with the basins of the Rhine and Weser rivers and is part of a waterway connecting the Rhine industrial region with the North Sea. The cities of Rheine, Lingen, and Leer are on the Ems and the seaport of Emden is near the mouth.

(6) (Expanded Memory Specification) A technique that allowed DOS to reach beyond 1MB of RAM. Introduced in 1985, EMS provided access to 4MB, 8MB and later 32MB of expanded memory by bank switching through a 64KB page frame in the upper memory area between 640K and 1M (see UMA). Users had to specify how much EMS was needed, and applications had to be written for EMS (Lotus 1-2-3, AutoCAD, etc.), or they were run with EMS-compliant software such as DESQview. In IBM PC XTs and ATs, EMS required a board and driver, but 386 PCs could create EMS from extended memory. When Windows came out, it allocated EMS automatically. See DESQview and extended memory.
