    From Doug Laidlaw@2:250/1 to All on Mon Nov 4 09:55:36 2019
    In Windows, we were always told to keep running services to a minimum.
    They were called TSRs, "terminate and stay resident," and sat in RAM,
    taking up space there.

    In Linux, there are many services. Their impact doesn't seem to be on
    RAM, but on the CPU usage. What is the difference, just more RAM available?

    No, TSRs are a DOS thing, not a Windows thing, and considering that DOS
    could only directly access 640 KiB of RAM without using any special
    tricks =E2=80=94 which would only work on 80286 and above anyway =E2=80=94 = the
    consideration was indeed that too many TSRs take up RAM.

    UNIX machines =E2=80=94 or at least, from the same era onward that MS-DOS/P= C-DOS
    appeared on the scene =E2=80=94 have always had more RAM available, because UNIX is a multiuser operating system, and DOS couldn't even do
    multitasking, let alone being multiuser.

    Oh Dear! I've had a memory flash back to those long evenings trying to
    get a mouse, CD, Sound Blaster installed in upper memory to get a game
    to run

    HIMEM.SYS and EMM386,EXE be gone ! vanquished....
