This is.... gibberish. What's going on here? Are we being trolled?
The Multics operating system, which was funded by the DARPA at MIT's Project Mac for 10 years, was superior to Unix from a technical standpoint, and it used segmentation.
Unix has Paging but not segmentation. Segmentation allows you to grow a memory block without having to copy as it grows, something that just plain paging cannot do.
