Installing Operating System (OS) needs registration to function fully. Maybe, you install unregistered OS that's why it comply the needs of CD. I suggest you reformat it. Buy the retail OS (if can't afford crack your OS out) so it won't ask you again about the OS error.
What is the function of control unit?
It also takes help from the arithmetic logic unit , whenever required. The control unit is very important for computers functioning . The control unit has outputs which take charge of the activities of the entire device. Some regard the control unit to be an FSM or finite state machine which is used for hardware and software applications.
Control Unit and Microprogram :
There was a time when the manufacturing of control unitswas a difficult process, especially in designing it. But today the scenario has changed. A control unit is executed in the form of microprogram which remain in control stores. There is a micro sequencer which chooses the words and certain portions of those words which directly manage the various computer parts. These parts are arithmetic and logic units, buses, instruction registers, registers and input/output. Today the latest computers may possess subsidiary controllers for every subsystem, which would be supervised by the main control unit .
Functions of Control Unit:
A control unit can be described as a sort of circuitry that supervises and controls the path of information that runs over the processor and organizes the various activities of those units that lie inside it.
• It carries out many tasks such as decoding, fetching, handling the execution and finally storing the results.
• It controls the execution of instructions in a sequential order.
• It guides the flow of data through the different parts of the computer.
• It interprets the instructions.
• It regulates the time controls of the processor.
• It sends and receives control signals from various peripheral devices.
A control unit is a major computer part which helps in the functioning of the central processing unit and in turn runs the whole computer.
Yes, real-time operating system is the type of operating system most people use on their desktop and laptop computers today. For a real-time OS, programs are executed the instant they are sent to the CPU without batching or queuing.
Is it always a good idea to improve the performance of an operating system?
Yes, you should always try to optimize your operating system. This includes defragging and removing viruses and malware from the system.
MINIX (short for Minimal Unix) is a Unix-like operating system written by Andrew Tanenbaum. It was originally created to teach microkernel programming to university students.
What makes up a multimedia system?
The basic components of multimedia system are its user, a computer system and multimedia. Multimedia comprises one or more of video, text, audio and images.
Every computer must have an operating system?
Yes, all computers need a set of instructions or program to tell it how to function. This what a operating system does for a computer.
What is the purpose of an identity manager system?
The purpose of an identity manager system is split into three areas. The pure identity function, which involves the creation, storing, and deleting of identities. User-access function, which allows certain people to access certain devices or services. And the service function, which delivers personalized content to users and their devices.
Why some of popular operating system are not support for posix compliant?
Without getting into too much detail, it's largely a choice made by developers of the system whether or not providing a POSIX-compliant or at least POSIX-compatible system is worth the effort.
The aim of POSIX is not to be a standard defining operating systems themselves so much as standard for a suitable environment for source compatibility between different operating systems, primarily those of a Unix-compliant or Unix-like design. I believe full POSIX compliance is a requirement of the Single Unix Specification in turn, the SUS being a standard that actually DOES define what an operating system should be (In this case, to be considered a real UNIX system. Needless to say Windows is nowhere in the neighborhood of SUS compliance.).
The idea behind POSIX is to make it much easier for Unix/Unix-like software developers to write software and have it available for those who provide selections of software for any given Unix platform. Program written for POSIX OS A can be built for POSIX OS B with little or no changes to the source code of the program, usually the only changes needed are bits closer to the metal or usage of libraries not concerned with POSIX compliance.
POSIX does not concern itself or define any standard for binary compatibility. This is not just a matter of scope but the fact that such an application of the standard would only be useful on OS-to-OS ports of a program being made on the same system architectute, which would make POSIX less useful for Unix systems, which are frequently deployed in mixed-architecture environments.
Windows has a POSIX layer available as a download, but generally it's a limited, only halfway-compliant POSIX system. Windows itself is not designed in a way that is generally POSIX-compatible, since it's software architecture is a fundamentally very different thing from Unix. For most Windows users and developers: POSIX compliance is of very little practical use, as Windows' design still requires some very POSIX-unfriendly additions to source code to build correctly on Windows. For Windows to become a POSIX system would require Windows itself to be completely remade in ways that breaks all backwards compatibility with previous versions of Windows, something most users would not like. When open source software is ported to Windows, one generally uses MinGW or tools like cmake that provide build scripts/files for POSIX and non-POSIX systems alike.
What are the classical problems of synchronization?
The Readers-Writers, The Dining Philosopher, The Dining Savages, The Cigarette Smoker and The Sleeping Barber. There are a lot more, these are just some.
What is the meaning of a 'pirated operating system'?
Pirated:In terms of computing is act of copying the software in illegal form and against law. More, the details of user is not provided to the software vendor, nor price of license.
The license is a certificate that show that your software is genuine. There are a lot of advantages of using genuine software, but due to lack of money, or just to have try, people across world are using Pirated Software to make their work on.
Please note that these are applicable on complete and commercial application. Not applicable for free and Open Source application.
So, Pirated Operating System is somewhat an Operating System, like Windows XP or Vista, whose license and certificate of originality is not with the user.
I want to bring this to our all reader that Piracy is Crime. And don't try to be Hero to play against Law.
In case of lack of Money, Better Try Open Source.
Linux and other flavor of Linux are open source. Go and select one for you. It can be downloaded or shipped to you.
Which is the best iPhone data recovery technique?
When it comes to the iPhone data recovery, the first occurred to me is the TunesKit iOS Data Recovery. Why? Because it can rescue diverse types of data such as photos, videos, SMS, app data, etc. Besides, it is fully compatible with all iOS devices and iOS versions including iPhone 12 running iOS 14. In addition, with Windows and Mac versions, it provides three recovery modes: recover from iDevices, recover from iTunes backup and recover from iCloud backup. Finally, with the easy-to-use interface and simple steps, this iPhone data recovery software can retrieve data no matter what causes the loss and no matter whether you have backups or not.
Yes there is an operating system called Lunix, not to be confused with Linux. Lunix is a Unix-based operating system for Commodore 64 and Commodore 128 computers.

How do you install fedora and Windows 8 in a dual boot mode?
First make partitions for the operating systems - first windows 8 then fedora partitions of / swap and /home - then
First install window 8 after having made partitions for both operating systems, then install fedora to the partition previously made for installing it. Grub bootloader detects windows 8 and adds entry to the menu.
What are two functions of an operating system?
controlling hardware access and managing application s
Entensity.net is a website sort of along the lines of 2leep.com, neatorama, boingboing and the like. It focuses on funny, obscene, violent and sex filled videos, links and pictures. An awesome collection of interesting items.
After Mac OS X 10.4.11 (Tiger) you need to buy an upgrade to Mac OS X 10.5 (Leopard) the current highest version of which is 10.5.8. Leopard will be as high as a G5 can go as 10.6 (Snow leopard) requires a newer Mac with an Intel processor.
In an operating system a layered structure is composed of a kernel, some servers, and some user level libraries. All of these put together are a layered structure.
For FREE, you can get a pair of tools called GETDATABACK. (Search for the PORTABLE versions). make sure you have a spare hard drive to recover to. if you recover one file and place it on top of another file, the other file becomes much harder to recover.
