- Subject : Operating Systems... To : Everyone
- From : Yoho Yip User Note: Precision Programmer
- ───────────────────────────────────────────────────────────────────────────────
- DOS - What most of us here probably use... Was originally designed for and
- 8088, and was not made with upgradablility in mind, just as the 8088
- wasn't exactly made in the best possible manner. Is not very powerful
- compared to some to some of the other O/S's, because of the fact that it
- was originally designed for the 8088, and to maintain compatiblility,
- they have not been able completely re-write the system. SUPPOSEDLY -
- DOS 7.0 is to break the 640k barrier, with some sort of dos-extender/
- virtual-remapping system, but we'll wait and see. Now that Microsoft is
- pushing NT like a bitch, who knows when the next DOS release will be.
- DOS EXTENDERS - Used on top of DOS, makes dos make use of the extra memory,
- (among other things) capabilities of the 286/386/486/Pentium etc. chips
- protected mode capabilities. There are many O/S shells which use DOS
- extenders to run on top of DOS. Examples of these are Windows/286 2.11
- all the way to Windows 3.1, Desqview, Desqview/X, and some other lesser
- known systems such as the GeoWorks (correct name, don't remember) system
- and several other smaller task swappers, and the like.
- WINDOWS 3.1 - Is a extremely LARGE shell for use on top of DOS, when inside the
- shell, it offers you the wonderful pleasure (sorry, couldn't resist :] )
- of a GUI. It also allows you to task-swap DOS and Windows programs in
- little virtual windows. I.E., allowing you to do multiple tasks at the
- same time. The problem with Windows is that it is SLOW, and since it is
- running on top of DOS, it is not able to make full use of the 386/486/
- Pentium chips.
- OS/2 2.1 - Was originally IBM and Microsoft's attempt to wipe the slate clean
- and start with a new operating system. Then IBM and Microsoft started
- feuding (as usual), and it is now solely IBM's product, though IBM has
- rights to the NT kernal, and/or Microsoft has rights to the OS/2 2.1
- or vice-versa, not sure. OS/2 2.1, was supposed to be easily ported to,
- I.E, changing existing Microsoft Windows applications to run on it, yet
- it didn't work that way, so the major setbacks that IBM experienced while
- trying to push OS/2 were a) the well known financial problems the've been
- having b) it took an extrememly long time to port applications to the
- system, example: it took 3 years to port Pagemaker from Microsoft Windows
- to OS/2 c) buggy, the first releases of OS/2 were extremely buggy. OS/2
- does have several major advantages over DOS, it is able to make full use
- of the processing power of the 386/486/Pentium, it is still able to run
- DOS programs, it's a GUI (plus for some people), and I had another reason
- but just forgot.
- WINDOWS NT - Windows NT is Microsoft's baby. It offers many of the same things
- as OS/2, yet is better in several aspects(OS/2 does have +'s over NT also
- I just skipped them). For one, there are an extreme large number of
- people using Windows for DOS right now. Switching to NT (assuming you
- have the hardware) would be no problem for these (basically)
- computer-illiterate people who just know how to move the mouse and click
- the button. Besides a couple extra features here and there (OLE, etc)
- Windows NT *LOOKS* almost exactly the same as Windows for DOS, with the
- exception of instead of having (C)lose on your program manager menu, you
- have (S)ystem Shutdown. The entire "sameness" of the two is a plus for
- many people because all of the people who's system boots up to the DOS
- version of Windows, and whose companies spent two years training them on
- how to move around the mouse and click the button wouldn't have to learn
- anything new, besides the fact that they need to use (S)hutdown instead
- (E)xit or (C)lose or whatever it is. Another MAJOR advantage to Windows
- NT is that it was written with software developer's SPECIFICALLY in mind,
- so that it is not too tedious of a job to port DOS Windows applications
- to NT. Another thing is that NT will still run your existing Windows
- applications(just not as well as if they were re-compiled). (I forgot to
- mention: OS/2 also runs Windows applications, but not Enhanced mode
- ones... I think that is coming in the next version, don't remember)
- Another thing that NT has on its side is that Microsoft is behind it, and
- Microsoft has one hell of a lot of money to push NT.
- DESQVIEW - Desqview is a very decent task-swapper for DOS. It works very well,
- is not bulky like Windows NT(70+ megs), OS/2(30+ megs), etc... and is
- small and to the point. It is easy to use, and gets the job done, and
- don't have to maneuver your way around a desktop.
- DESQVIEW/X - This is a build-off of desqview, which has grown into a full-size
- kick-ass shell for dos. Like Windows for DOS, Desqview/X runs on top of
- dos. It uses a graphical interface, but unlike Windows, the interface is
- completely configurable. The system can look like anything from a
- straight no-border/no-graphic/text-type desktop, to looking exactly like
- MOTIF (in fact, they took motif, tore out its desktop section, and made a
- little library type thing out of it, that you just add on) the desktop/
- menus can be manually configured, or you can use the little add on
- packages which were made to look like other systems. I think there is
- even a Windows one in there(don't exactly remember). Anyway, like normal
- Desqview, DV/X runs normal DOS applications, it also runs Desqview/X
- applications. If you have the need to run Windows applications, you can
- run Windows in a DV/X Window, and do whatever you like in there. DV/X is
- also very small... something like 7 megs EVERYTHING installed, and if you
- just want the very basics, it is only like 1.7 megs or something. The
- spectacular thing about DV/X is it's X-Windows implimentation. Imagine
- this senario: Network, 3 IBM's running DV/X, 2 Macs (using and X-windows
- deally), 3 SUN-Sparcstations(UNIX, using X-windows thingy)... Ok, I'm on
- one of the IBM's... and open 20 Lotus 1-2-3 windows, and am down to one
- meg of memory. I need to run Microsoft Windows, but don't have the
- memory for it... (MS Windows in one Meg? Ha!) So I make a couple
- config changes, and vwalla, I am running Windows, didn't close any 1-2-3
- windows... Check my free memory... STILL one meg. What's happening? I
- am running windows on a different one of the IBM's on the network, using
- it's memory. Still runs basically full speed, but is not taking up any
- of my memory, or virtually any of my processing power either. Ok,
- another thing, you can set access levels for different users, I.E, what
- LOCAL drives on the other computers people have access to... I.E, I could
- copy something on MY A: to the A: on someone elses computer, assuming I
- had the access. Anyway, assume I have full access to everything. I've
- seen some 1/2 decent Mac applications out there, so I open up the Mac
- drive (from my IBM still)... pick a program, and run it. Gee, seems to
- run fine on my IBM... Lets try the sparcstations... Their Unix
- applications work too... Anyway... I've done my share of plugging DV/X
- for now. It (and UNIX) are my personal favorites... but this was just to
- give you an example of Desqview/X. In a network enviornment, DV/X does
- the whole other computer deal with any computer that has an X-Windows
- implimentation. Even Windows NT is going to/does/whatever have one.
- -End of Plug for Quarterdeck's Desqview/X- :)
- UNIX - Unix is probably the most time-tested operating systems of the entire
- microcomputer world. It has implimentations on virtually every major
- platform. It allows for multi-tasking(task-swapping, depending on the
- processor), and is just, really neat. (Having trouble describing it)
- Unix comes in MANY different flavors. It is generally like DOS though,
- a command-line type operating system. It looks a lot the same, with
- several little quirks, like different commands than "dir", etc, though
- some are the same, such as "cd"... Unix uses the '/' slash instead of
- '\' slash, and can have much longer filenames. It's main +'s are that it
- is very time-tested, has MANY applications for it, is a GREAT
- multi-tasker(task-swapper)... and is just plain old neat. I am also
- very partial to UNIX because my uncle, a vice-president of Intel won the
- fourth (?) Intel Fellow award, and was named "The Father Of Unix"...
- -------------------------------------------------------------------------------
- Anyway, this is the end of my speal, hopefully it should clear up a COUPLE
- things in differences between operating systems. I know it was a little biased
- at parts, but I guess that's life. It did not go into very much detail about
- everything, so if someone wants a LOT of information on something I could
- probably give it to them if they ask specific questions. This was also just
- done of the top of my head, and typed online, so if I screwed or mixed
- something up, I apologize, feel free to correct me. Also, don't think that
- this is completely from reading or other people's oppinions. I HAVE used every
- operating system/dos-extender/whatever that I listed here. And I must say,
- that ANY of them are pretty spectacular when you are running them on PC's with
- anywhere from 1 to 32 Pentium processor's parallel processing. (Comdex was
- GREAT!) Anyway... I didn't go into the Macintosh, or IBM/Apple's joint-venture
- (PowerPC)... so if there are questions about them there is the possiblity that
- I could answer them. One last comment I will make is that it looks very
- promising for Microsoft... They basically have the money to push NT, and that
- is what really counts.
