There are a number of factors at play here:
1. Preinstallation (Linux does not have deals with major manufacturers so they are not generally installed by default on computers or even a choice when purchasing)
2. Familiarity (People use what they're used to don't like to migrate)
3. Software incompatibility (Some software will not run on Linux; this software might be highly desired or necessary for the users)
4. Perceived difficulty (Linux has origins in the programmer/hobbyist communities and the misconception that installing/running linux is difficult persists)
5. Lack of support (unless you are using an enterprise Linux [ex RHEL], there is no official corporate support. Trouble shooting must be done via wikis, forums, mailing lists etc.)
What is the difference between a single-user and a multi-user operating system?
Single-user OS is that OS which support only one user at a time. for example: DOS, WINDOWS 3X, WINDOWS 95/97/98 etc. Multi-user OS is that which support more than one users at the same time. in these types of OS there is a server and all the users are provided different terminals. these terminals are connected to the server. for example: UNIX, LYNIX, WINDOWS VISTA etc. == ==
Just that- single user has one person using it; multi user many.
What part of the operating system that allow the the user to communicate with the computer system?
Generically speaking, it is the shell or user interface. It may be a command prompt or a graphical user interface (or a combination of both). The layer of the operating system that is directly accessible to the user is known as the application layer; it runs all of the applications that the user interacts with.
What are the main functions of the operating systems?
Without an operating system, a computer would not operate, and a blank screen with a message (something like) system not found, would be the result.
Is there a difference between a computer in an automobile and a personal computer?
They are both computers the difference is that they use different kind of software and cannot be compatible with each other. So you cannot make your car computer play mp3 or something like that.
What computer is similar to the mac operating system?
A computer is a piece of hardware, so no computer can be similar to Mac OS X (a piece of software).
If you are inquiring what other operating systems are similar to Mac OS X:
NextStep - operating system released by Next. Next was purchased by Apple, and NextStep was used as the base for Mac OS X.
FreeBSD - most low-level utilities in Mac OS X were updated with ones from FreeBSD
If you are inquiring about what hardware platforms are similar to that of the Macintosh:
Generic PC - Intel Macs share the same processors, and most of the same buses and connectors, They differ mainly in the firmware: Macs use EFI, a firmware created by Intel. Most PCs use a BIOS, which maintains compatibility (and some design flaws) with the original IBM PC of 1981.
IBM POWER Workstations - Older PowerPC-based Macs share much of the same architecture with concurrent IBM workstations.
BeBox - A PowerPC computer released in the mid-90s, had a similar architecture to concurrent Macs.
What is the main advantage of the layered approach to system design of operating system?
The main advantage of the layered approach is modularity. The layered are selected such that each uses function and services of only lower level layers. This approach simplifies debugging and system verification
In this case the system is easier to debug and modify, because changes affect only limited portions of the code, and programmer does not have to know the details of the other layers. Information is also kept only where it is needed and is accessible only in certain ways, so bugs affecting that data are limited to a specific module or layer.

The system consists of CPU, Main Memory, I/O Module, and System Bus.
What are the categories of operating system based on the hardware machine they run?
there are two types of os based on your hardware machine. first is nos and second is cos base.
What are some jobs that an operating system might do?
Initializing programs.
Running drivers.
Managing memory.
Providing API's to programs.
What are the advantages of operations management buffering?
I'm studying business behavior at AOU
i got this answer half from the book of my course and the rest from Internet
i hope you find it useful =)
Buffering is a try to minimize the environmental disruption by buffering or insulating the operations function from the eternal environment
-organizations use buffering in order to exercise control over the global market
- secure the supply for future in case of unpredictable circumstances

What are the three main purposes of operating system?
The OS allows the computer programs to function correctly by allowing them to communicate with other programs and the computer. Windows is an OS, which bring all the programs together and allows the user to access them. The operating system manages the use of the hardware among the various application programs for the various users and provides the user a relatively simple machine to use.
What are the four steps to run a program on a completely dedicated machine?
a) Reserve Machine Time b) Manually Load Program Into Memory
c) Load Starting Address And Begin Execution
d) Monitor And Control Execution Of Program From console
Name and explain five resources of an Operating System?

Which operating system is the most popular in the world?
Well I don't know popular as in 'I refuse to use any other even if it was available' But Windows is the most used through out the world, since Bill Gates got there first. Contrary to popular belief, Apple isn't really close, probably about 30 percent, though it could be more popular than that in America which is why it seems like Apple can compete. But really Windows is without a doubt King, though Microsoft really dropped the ball on Vista and who knows about the next one, so there's no real guarantee that Windows will not have more competition or become less popular, but even then most people know it and are familiar with it, so that's why it will still be used a lot even if something else besides Apple comes along.
Windows, because the world is full of poor people who can't afford Macs, and since they're poor, they haven't been able to afford a good enough education to know about Linux. Therefore, Windows is an alternative OS. You have to be poor andstupid.

- File manager.
- Scheduler.
- Process manager.
What is design in modular form and its advantages?
Basically, design in modular form means designing a whole product (see program or software piece) based on modules (functions, classes, and a like). The advantages would be a flexible structure, easy to maintain, debug, upgrade and also customize with respect to changing customer requirememnts.
What are turnaround time and response time with reference to Operating System?
Turnaround time is the interval between the submission of a job and its completion. Response time is the interval between submission of a request, and the first response to that request.
What operating system works on a desktop computer notebook computer or mobile computing device?
operating system is a complete operating system that works on a desktop computer, a notebook computer, or mobile computing device.
