- Extended memory (Wikipedia)
In DOS memory management, extended memory refers to memory above the first megabyte (2^20 bytes) of address space in an IBM PC or compatible with an 80286 or later processor. The term is mainly used under the DOS and Windows operating systems. DOS programs, running in real mode or virtual x86 mode, cannot directly access this memory, but are able to do so through an application programming interface called the Extended Memory Specification (XMS). This API is implemented by a driver (such as HIMEM.SYS) or the operating system, which takes care of memory management and copying memory between conventional and extended memory, by temporarily switching the processor into protected mode. In this context, the term “extended memory” may refer to either the whole of the extended memory or only the portion available through this API.
- Bitter Lake, Seattle (Wikipedia)
Bitter Lake is a neighborhood in Seattle, Washington, United States, named after its most notable feature, Bitter Lake. It was a mostly natural forest of Douglas-fir and Western Redcedar, inhabited by Native Americans, until the late 19th century. Development especially picked up when the Seattle-to-Everett Interurban streetcar reached the lake in 1906. A sawmill operated in the area until 1913, when most of the trees had been cut down.
