What is the difference between client operating system and server operating system?
A client operating system is generally a single user operating system where only 1 user can be actively using the computer at any one time. Video and audio are important to the 'users' to have a rich experience.
A server operating system is a multi-user operating system where it is optimized for multiple user access at the same time sharing all of the resources. Audio services may be limited and the video experience is not very important as many servers do not have dedicated monitors or keyboards (operate headless)
Define the essential properties what types of operating system Batch?
Jobs with similar needs are batched together and run through the computer as a group.
Use a Boot up CD or Boot up Floppy to format the C: Drive and then install ur Operating System. to create a boot floppy go to control panel -- > add and remove prog -- > the last tab (creat boot disk)
What type of software may do maintenance and repair jobs that an operating system cannot do itself?
Utility Software
What is the difference between rtos and OS what are the advantages and disadvantages of rtos?
an RTOS is much better than anormal OS because it is time sensitive, fault tolerable and allow multiprocessing. that are not supported by all OSs
A real-time operating system is intended for systems that need to tightly control responsiveness and performance. With an RTOS you can prioritize operations such that the most critical areas of the application get control of the processor exactly when they need it. All other lower priority operations are paused.
An RTOS also gives you all of the other advantages of an OS:
- a consistent coding platform
- a rich set of APIs to save coding time and errors
- processor housekeeping functions
- hardware abstraction
What is the function of Plug and Play?
In computer terminology, this term means a device that can be installed into a computer without being configured and that won't cause hardware conflicts.
The function PLug and PLay is a procedure the computer attempts to perform when you first plug a USB device into your computer. If you have Windows Vista, the plug and play works everytime you connect any device. Any operating system earlier than Vista will only plug and play fewer devices depending on your service pack and the software updates. Devices such as Cellular Phones and MP3s need to be manually installed using the provided software install disk. PLug and PLay does not support LPT port devices and standard PS/2 mice and keyboards. Your computer automatically uses those ports as long as there is something plugged into it.

What are the criteria for installing Linux operating system?
For the installation of most free/open-source desktop 'Linux' distros, you will need the following:
1: An Intel/AMD type x86-32/64bit machine with at least 512MB RAM & 10GB HDD; preferably a 'spare' one - dual-booting IS a BAD idea, although many 'Linux' operators run several 'Linux' distros on the same machine!
2: Belief in there being such a thing as a free lunch:
You want something 'better' than Windows, but either cannot afford to buy or aren't prepared to buy a new Mac machine (you don't see many second-hand Macs). But, nearly ALL of the software & applications can be downloaded for 'free' from your OS's 'synaptic package manager': you WILL find that there can be such a thing as too much choice! There are DOZENS of 'Linux' distros out there.
3: A love of passwords:
Generally, you need a password & permission to do anything, even if you're the system administrator or sole user. This is because 'Linux' distros are built with multiple users in mind.
4: Plenty of time on your hands:
Unless you're just an end-user who just wants a PC for web-browsing, emailing, downloading, ripping, etc., you may well find yourself spending hours in 'command terminal' trying to install proprietary hardware, etc. This is where you find that 'freedom' isn't entirely free. However, most 'Linux' users are 'system-operators' rather than consumers, which is why they get 'Linux' in the first place: OK, they're hackers; & 'Linux' is perfect for hacking, because it built like Lego(tm) or Meccano(tm).
5: A love of variety or incosistency:
You will ideally have a liking for changing your operating system at least once every six months, & virtually starting all over again, because you hardware no longer works with the 'updated' system. Realistically, the people who like 'Linux' also tend to like like giant DIY toyshops! "If you've not changed your 'Linux' distro in the last 12 months, it's about time you did!" (paraphrased from I can't remember which online 'Linux' website).
6: A love of forums:
You will spend a LOT of time looking on forums for advice on how to resolve problems, install hardware, etc., much of which will neither make sense, nor be relevant to the particular version of the distro you're using. Many 'Linux' distros have a certain self-justifiable pride about being community-based. Be aware though, that many 'Linux' types don't care a jot whether or not you use 'Linux' - they're a bunch of quasi-anarchists, who take pride in their individuality AND the individuality of their individual machines, who nevertheless tend to be generous with their advice, even if you don't understand it - you can always learn.
7: A willingness to learn:
Unless 'Linux' is your first OS ever, in which case you won't be any the wiser, you will have a LOT to learn - 'Linux' is NOT Windows or Mac, & many of the processes are quite different. If you're not just an end-user, you WILL learn some coding protocols. Until you've mastered you own 'Linux box' & tailored it to your own requirements, in which case it's time to either upgrade or change to a different 'flavour' of 'Linux', you will learn that EVERYONE else's 'Linux' distro is better than yours!
If you're seriously thinking of changing to 'Linux', don't say you haven't been warned!
Good luck,
Archangel
What platform does the operating system run?
The operating system is a platform itself. There are many sub-platforms, such as .NET in Windows, which includes WinForms, WPF and maybe more. A better question would be "What platform does .NET run on?" or "What platform does MFC run on?" Both of these questions are noobish, though, but they are better to understand.
Is windows 7 operating system a type of system software?
Well, it depends on how you look at it.
System Software is actually part of the Operating System not the other way around. System Software is actually the more important parts of the OS, so use care when digging around and moving things.
What is modification record in system software?
Modification record contains the information about the modification that has to be done in the object code during program relocation.
The general format is
Col 1: M
Col 2-7: starting location of the address field to be modified relative to the beginning of the program
Col 8-9: length of the address field to be modified in half bytes.
Where can I learn about computer operating systems?
This depends on which operating system you want to research. For example, there are three major OS'es. Those are Mac, Windows, and Linux. For Mac, you can go to apple.com and then lookup "Mountain Lion" in the search bar. To research Windows, o to Microsoft.com and find Windows. For Linux, you can goto ubuntu.com or look up fedora Linux on google. You can also find information about many OSes using wikipedia.
What are all the Extended services provided by the operating system?
Ubiquitous communications
Network OS extension
Binary large objects (BLOBs)
Global directories and Network yellow pages
Authentication and Authorization services
System management
Network time
Database and transaction services
Internet services
Object- oriented services
What operating systems can you run on an Intel Pentium III?
The type of operating system to use depends also on the amount of memory in the computer. These older computers usually feature 64-256 megabytes maximum.
64 mb + i would recommend using a light version of Linux (Google it, there will be a few light Linux versions, download the CD image, and write it to a CD, then Boot off of that CD on the older computer)
256 megabytes+ it is possible to use windows Me or windows 2000. Windows XP can work, but it is not worth buying XP. If you have a CD with XP on it, go ahead and try that.
Linux is a good choice.
Which operating system was often used for desktop computers released in 2006 and 2007?
Windows Vista was common on computers sold in 2006 and 2007
What are some of the common features that operating systems and application programs share?
Many commercially available software applications and operating systems have features built into the program that are labeled as accessibility features. These features can typically be turned on or off by a user. Examples of these features include: reversing the color scheme (to assist people with low vision), showing a visual prompt when an error tone is sounded (to assist persons who are deaf or hard of hearing), or providing "sticky keys" that allow a user to press key combinations (such as control-C) sequentially rather than simultaneously (to assist persons with dexterity disabilities). This requirement prohibits software programs from disabling these features when they have been activated prior to running the application.
Is any other operating system in this world?
There are quite a few alternative operating systems to Windows - These include UNIX, MS-DOS and OS-X (mac)
What Operating System is typically best for server hosting?
Windows is typically the best system for server hosting. The reason for this is compatibility and better "bang for your buck." Frankly in the corporate world there are cheaper Windows PCs and for that reason it is the widely used operating system which makes sense for the use of a compatible system to host a server.
How do you install a dual operating system?
From my experience it is easier to start installing older version whatever it is. Because newer OSes have better boot compability with other OSes. Exclusions from this rule are Linux and Windows. It's better to istall Wndows and after that in a separate partion Linux.
How do you partition a system partition?
You can do it in 2 ways:
1：you can try disk management,You can change/make partitions on your hard disk even when there are still files on it
2:you can try three party partition manager software,like as gaprted, MiniTool partition wizard and so on.
Why can't you to eat before an operation?
Because you could aspirate it into your lungs. Anesthesia dulls the reflexes that normally close off and protect your lungs from foreign matter entering them.
What is a disk operating system?
An operating system (OS) is software that controls the internals of a computer. The first large computers did not have operating systems or programming languages. You entered insructions through lights on the main console. The first operating systems were on punched cards, which you read into computer memory. They would then control instructions entered on decks of punched cards (a "computer program"). When you turned off the computer, the memory would NOT be cleared, so the next time you turned on the computer, the operating system would still be there. At this time, computers consisted of a "central processor" (the equivalent of a mother board today) that took up a room, punched cards input and output, and printers. There were no magnetic devices such as tapes or hard or floppy disk. The problem with this was that it required that everything from your operating system to your program be entered in "machine" language - binary codes that told the processor what to do (move something, compare something, add, subtract etc.). The next step was to create an operating system that was "flexible" and easily updated. So the "TOS", or Tape Operating System was created. This consisted of adding a tape drive to the computer complex, and storing the "OS" card deck on tape. About this time, they changed over to "volatile" memory that was cleared when you powered down the computer, so the OS had to be re-loaded every time when you turned it back on.
In this way, if you wanted to change operating systems (go from a financial operating system that handled money to a scientific OS that handled spiral decay of satellites), you just stored that OS on a tape and mounted the tape you wanted, which you then loaded into memory. It was at this point that the "general purpose" computer was born. Up until then, each computer was dedicated to a task such as financial, or scientific or military.
The computer then evolved into "magnetic" systems - tape, disk, cylinders, platters, CRAM (Card Random Access Memory) - there were many different kinds of storage that could be used for input and output. The next logical step was to take the TOS and put it out on disk (or even magnetic cards), so you didn't have to mount a tape to load or change an operating system. This was DOS (Disk Operating System). DOS was originally on mainframe computers.
At the same time mainframe computers were maturing, so was the "hobby" computer. It followed the same path as mainfame, only slower, so it went through a "console lights" phase where you could only do something through the lights and/or switches, into an "operating system" on tape and finally into a DOS (of which there were several flavors). Today, most operating systems are DOS, but they might be stored on media other than disk, such as Thumb Drives, which are really solid state chips and not disk drives. The PC "BIOS", the Basic Input/Output Operating System, is an example of a DOS on a chip that is used to initialize your computer so it can read/write from all the devices that it consists of.
