-
- I missed the beginning of the thread, but I haven't seen anyone mention
- daemons, named pipe services, sockets, and other IPC type applications
- of multiprocessing. DOS/Windows does limited IPC, NT will probably do
- it robustly (Dave Cutler knows how to design robust OS's even if
- Bill Gates is clueless).
-
- Unix allows several different flavors of multitasking, multiple processes
- launched from a single command line is one flavor, and is probably the
- most visible to the user. Multiple command lines is another user-oriented
- flavor, whether the additional commands are put into background or are
- running in a different console window.
-
- Then there are the programs that run essentially in background doing
- nothing but waiting for input, these are database servers, network
- daemons, cron, etc. These programs do essentially what TSR's do for DOS,
- but take advantage of the multitasking features of Unix to continue
- processing while other work is being done on the same system.
-
- All of this is common knowledge for most of the readers here. For those
- folks that haven't used a true multitasking system long enough to find
- it's usefulnes, it's difficult to envision just how convenient multitasking
- is. Like any tool more complex than a hammer, tho, it does take time to
- learn to use efficiently.
