[BSG] Today called "page-locked" Said of code or data that is fixed in physical memory, either by virtue of being in unpaged segments (individual segments can either be paged or contiguous in memory), or in segments whose pages are marked as being non-removable This is done for code and data that must be either be run or referenced at an equal or lower conceptual level than the I/O and page management routines doing the paging, data actually being transferred to and from I/O controllers, or code which must compete with such code for resources and its data In practice, this means page control, the scheduler, the disk routines, low-level I/O control routines, interrupt handlers and vectors, page tables, and that subset of the PL/I runtime (see pl1_operators_) that is used by any of those aforementioned that are written in PL/I Except as an experiment, code or data was never wired for performance reasons
A computer, organization, or person that is wired has the equipment that is necessary to use the Internet. Once more people are wired, the potential to change the mainstream media will be huge
