The x86 architecture has supported memory segmentation since the original Intel 8086 (1978), however x86 memory segmentation is a plainly descriptive retronym. 64 KB of memory (16,384 or 65,536 bytes), and whose directions and registers had been optimised for the latter. Dealing with larger addresses and extra memory was thus comparably slower, as that capability was considerably grafted-on in the Intel 8086. Memory segmentation could keep packages appropriate, relocatable in memory, and by confining significant parts of a program's operation to 64 KB segments, this system could nonetheless run quicker. In 1982, the Intel 80286 added assist for virtual memory and memory safety
