Which operating system enables you to implement homegroup?
Microsoft Windows products "Windows 7" and "Windows 8" and "8.1" allow you to set up homegroups and connect to each other.
How many operating systems can be installed on one hard drive?
Theoretically, as many as will physically fit on the drive. Some operating systems will only function with certain partitioning schemes, however. The bootloader used to select the different systems also plays a role. LILO only supports 16 entries, for instance. GRUB supports an "unlimited" number, but in practice is only physically capable of displaying a couple hundred entries (this can be worked around through complex chainloading procedures).
It depend on your size of Hard Disk and how many Partition you have...As many as you can install Operation System.....
What is the current operating system for Macs?
The latest version of Mac OS X is Mac OS 10.8 "Mountain Lion." It was released on July 25, 2012. Updates through April 22, 2013 have produced version 10.8.3
Difference between system software and operating software?
Assuming that you mean the difference between system software (the term used by Microsoft, Sony and Nintendo to refer to the operating systems used by the Xbox 360, PlayStation 3 and Wii respectively) and operating system, the difference is very minor.
If you mean the difference between system software and an operating system in the PC world, the term system software usually applies to things like the Device Manager in Windows or the Logical Disk Manager; software that comes pre-installed with the operating designed to interact with hardware on a fundamental level.
The term "operating software" when not used synonymously with "operating system" is usually used interchangeably with the term "system software" in the PC world, but it can also refer to software used to completely managed an external system.
Multitasking
Are different operating systems needed for different computing tasks?
Short answer: Not always.
Different programs and aplications are designed for different tasks. Now, is X software available for Y operating system? That is another topic.
Computing Tasks:
- Gaming, Office and Accounting Tasks, Development, Digital Marketing, Design, Audio/Video Edition, etc... are all CROSSPLATFORM (meaning it can be done in any OS). Desktop OSs, today, are more compatible with those kind of tasks, but many of them can be performed in mobile OSs too.
The question is more related to Hardware than Software/OS.
For example, if you're a Hardcore Gamer, you'll need a very "strong" machine with a very good graphic card (it doesn't matter if you'll have the latest versión of MS Windows/OSX/Ubuntu or any other GNU/Linux distro).
Hardware requirements change if you only want to use your device to check your email, video streaming sites and social networks.
What are the requirements of realtime operating systems?
Technically, all operating systems are "realtime." The term realtime just means it happens immediately, versus being delayed. Most operating systems today are actually a blend of realtime and "batch." Batch processing is doing something later, usually waiting until you have more than one thing (a "batch") to do. An example of batch processing is when a company processes your payment. They don't post each payment to their computer system - they wait until all the payments are in for the day (or at least a good number of them) and then post them as a group - so thousands of payments get posted at one time (posted just means processed through some financial system). Some businesses, such as banks, will use both realtime and batch processing for the same items. For example, if you make a deposit with a teller, you will probably be able to go to Starbucks next door, sign on the internet, and see the the deposit posted to your account already. This is "realtime" processing. However...this is probably only a "memo" post. This means it was only posted to the online system so that you can get to it through the internet or telephone. During the night, your deposit will be sent to a central site and batch processed with thousands of other deposits. The night post will be to the "real" posting system for checks, the "Demand Deposit Accounting" system, or DDA. The biggest use "realtime" operating systems is actually in what is called "embedded" systems. These are operating systems and application code that is running on a single board and embedded in something physical - a car, a toaster, a TV set, a DVD player, an IPOD. Today, if it is electronic, it probably has an embedded system (or even several). Embedded systems are primarily realtime operating systems - they collect some statistics in realtime and allow access to them later in batch mode (here are all the errors that occurred on your car since it was last serviced...) but their real job is to control the device they are embedded in - and do it in "realtime" or immediately. This means they must be: - dependable - they must operate in all sorts of conditions - hot, cold, dirty, greasy, noisy, vibrations etc. - timely - they must be fast enough to think about an action, and get it done right away. For example, if you are an embedded system in a car that controls skidding, you must be able to react to the skid in "realtime" - as it is happening, and control brakes, steering and gas as appropriate to what is happening (skid starting, car is curving to right, skid is ending). - flexible - in the previous example, the embedded system to control skids must be able to handle a car going any speed, curving right, left or going straight, know when it is "over compensating" and correct it etc. It must be able to make the same decisions a knowledable human would make in the same circumstances. - sized properly - again, the previous example. The embedded system must be able to recognize and react to thousands of varying facts (speed, direction, condition and status of mechanical systems etc.). You must have a processor fast enough to process the data in realtime, and enough storage to accept, and display, conditions and status of "analog" devices. Note - most realtime systems are in what we know as "analog" devices. This just means they have something mechanical about them. Most parts of a car are analog, as are most TV set these days. This is versus "digital", where parts don't move, signals flow to devices that are able to convert the final result to analog (for instance, a digital TV will receive a broadcast signal, convert it to a certain channel and pass it on to the screen to display. Even screens such as plasma and LCD are ultimately analog - they must decide which dots (pixels) to display, in what color and what shade. The decision can be made digitally, controlling the nuances of the display in realtime.

Five generation of the operating system?
First Generation (1940-1956) Vacuum Tubes Sponsored

The first computers used vacuum tubes for circuitry and magnetic drums formemory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951. Second Generation (1956-1963) Transistors Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
The first computers of this generation were developed for the atomic energy industry. Third Generation (1964-1971) Integrated Circuits The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitorsand interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors. Fourth Generation (1971-Present) Microprocessors The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer-from the central processing unit and memory to input/output controls-on a single chip.
In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handhelddevices. Fifth Generation (Present and Beyond) Artificial Intelligence Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Standalone Operating System
What is the difference between Uni and multi processer operating systems?
'Uni' is the opposite of 'multi', like 'Uniform' is the opposite of 'Multiform'.These are prefix 'Uni' and 'multi'.'Uni' is singular and 'Multi' is plural.Therefore, 'Uni operating system' is a system operated by one particular thing and 'Multi operating' system is operated by many such things that are used in 'Uni operating system'
What is an API Is MySQL an API?
MySQL is not an API MySQL is a database where you store data. An API is how you request information from another website.
Why is command interpreter not a part of operating system?
It is usually not part of the kernel since the command interpreter is
subject to changes.
What part of the computer that stores all programs and operating system?
I am assuming you're asking what part of the computer sotres data in general. Well that would be the computers hard drive. To learn more about hard drives, go to www.howstuffworks.com and search "hard drives".
What is in a GUI operating system?
A GUI operating system is really anything that uses graphics to control what a system does. GUI stands for "Graphic User Interface". So there for, MACOS, Windows, and the Main screen of Linux/Unix is considered a GUI, the operating system is the part of software that controls what the computer is doing.
Bureaucratic units designed to operate like private businesses?
This would be a government corporation. They are designed in order to take care of commercial activities for the government.
Describe the relationship between system call and system program?
A system call is a routine which lies within the program itself to request a specific service from the OS kernel. Ms Word uses a system call routine to run spooler.exe when the print command is clicked. Internet Explorer uses a system call routine to open port 80 (HTTP) to access the internet. A few system call commands are Get, Open, Read, Query, Save, Write...etc. Mind you, I'm not a programmer so that's the best I can do! LOL :-)
Essential properties of clustered operating system?
A clustered system combines multiple computers into a single system to perform computational task distributed across the cluster.
What is exec system call of UNIX operating system?
The exec family of UNIX system calls will overlay the current process with another process. It can be used to "chain" a series of programs to run together. When used with the "fork" system call it allows multi-tasking to occur.
1.How does journaling help an operating system recover from system failures?
Journaling keeps track of disk changes in a log which can be used to restore the file system to a known state in seconds in the event of system failure or crush or power failure.

How deadlock deals with operating system?
A deadlock is a situation wherein two or more competing actions are waiting for the other to finish, and thus neither ever does. It is often seen in a paradox like 'the chicken or the egg'. " When two trains approach each other at a crossing, both shall come to a full stop and neither shall start up again until the other has gone.
