- Forgive the obvious stupid question. With OS/2 being such multitasking,
- there would be several useful features found in networks which would be
- useful for a stand alone system as well. Of course I dont know much about
- LAN's and such, the only multiuser OS I'm familier with is VMS. I'm talking
- about more abilities with file sharing, especially amongst files between
- several tasks. More so if it makes programs not normally friendly for file
- access work more reliably in a shared environment.

- While this is true for the hardware, it still seems that 32-bit disk interface
- software could still increase performance. I'm not very familier with the
- two version file system in OS/2, other than that HPFS is very quick, and the
- FAT version is a lot faster than in DOS systems. it seems that for some things
- HPFS is slower than a FAT system. If it were to go 32 bit, wouldn't the HPFS
- be faster all the time?
-
- This is just idle thinking, and is probably wrong, I just don't understand some
- of these things, and I'm trying to learn.
