Questions tagged [segments]

segments are divisible parts of something usually associated:

  • in programing with memory segmentation (memory pages, or array/table/file division)
  • in Graphics with polyline/polygon parts or any visual division of objects (like hatching,grids,...)
  • in HW architectures,linkers,compilers with separate memory/code areas for program,data,stack...
