In a word... No. Linux is however, which is close to OS X, but is you wanted the source code from Apple, you aren't going to get very far.

No. When one operating system is running in a dual-boot setup, no part of the other system is running. Thus, it is not using any memory or CPU cycles. The only thing it affects is the amount of free space on the hard drive. Hard drive usage does not typically affect computer performance, unless you have the disk so crowded that there is no room for the swap file or partition.

The Average Total Cost (ATC) curve is above the Average Variable Cost (AVC) curve because the ATC is composed of the AVC and the AFC (average fixed cost curve). The AVC curve starts out low at low levels of output, and eventually, as more of the variable unit is added, AVC begins to slop upward. Conversely, AFC starts out higher, but as more units are produced, the fixed costs are spread out over more units so the AFC curve is actually a downward sloping straight line. When you add the AVC and AFC at each level of production and graph the result, you are given the ATC line which is a U-shaped curve above the AFC & AVC. An example of VC would be labor. In the short-run where plant size is fixed, in order to produce more units, you would have to hire more labor. As you add workers, you will initially see a productivity gain, but as more and more workers are added, their marginal output will fall. FC is simple. Suppose you have a factory that costs you $100/year to operate. If you produce only 1 unit that year, your fixed costs are spread out over the single unit, so $100 AFC. Now suppose you up production to 3 units and AFC falls to $33.34/unit. Go even further and produce 25 units and now AFC is $4/unit. Graph this line. The sum of these 2 curves, AVC & AFC, equals ATC.

Basically Computer is the combination of both Hardware and Software..

So in order to support software we are in need of a Operating System..

This is my point of view..

operating system is not a loading, When is trun on system(press the power button). first of checked all the hardware devices,for exmple hard disk,ram,rom and etc. When the all devices dected process further. Jsb

An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software. Keep in mind, however, that much of the work of an operating system is hidden from the user; many necessary tasks are performed behind the scenes. In particular, the first listed function, managing the computer's resources, is taken care of without the user being aware of the details. Furthermore, all input and output operations, although invoked by an applications program, are actually carried out by the operating system. Although much of the operating system functions are hidden from view, you will know when you are using an applications software package, and this requires that you invoke-call into action-the operating system. Thus you both establish a user interface and execute software.

True; for instance, USB devices can be used to upload viruses or other malicious software to a system.

Simply because it is not vague(or detailed) enough and can't carry out certain tasks

Apple has introduced Swift 5.1 as an updated version for the newcomers and programmers with some new features add on to this to make it easier to design better APIs.

Key Features:

Module stability defines a new text-based module interface file that describes the API of a binary framework. implementation details in APIs are hidden by opaque result types.

Improvements to SIMD and String types.

After Basic learning session, it's easy to get a job Then you need Swift Interview Questions for your better performance in programming

Correct Answer: Device Driver

Basically, you shut the computer down. Procedure for that depends on the specific operating system. Operating system is what makes a computer do things. Even the thing the loads the main operating system for a given computer is a small operating system in itself. For example, the thing that loads Windows or Linux up is called BIOS, and that stands for Basic Integrated Operating System. Once you exit all the operating system(s) you may as well shut down the machine (if it does not shut down by itself.)

Receiving incoming calls, transfering calls to different extensions, making calls and transfering..etc.

Scribus runs on most modern general-purpose operating systems, including Windows, Linux, Mac OS X, BSD, Solaris, and eComStation.

Classification of Advanced OS is done as below:Architecture driven systems, and Application driven system. 1. Architecture driven: * Network OS * Distributed OS * Multiprocessor OS 2. Application driven: * Database OS * Real Time OS * Multimedia OS

One of the most important tasks that an operating system does is manage the memory requirements of your computer. We discussed earlier how current day operating systems are Multi User. This means that many users will be using the facilities of the computer at the same time, including its memory, to run their own tasks. Imagine if you had ten people sitting and working around your desk, and each of those people put their paperwork all over the desk. The desk would soon become unmanageable, with the paperwork hard to find or even lost. Eventually all ten people would probably not be able to complete their tasks. Somebody needs to take control and organise the chaos - on a computer this is one of the jobs of the operating system. As an example consider the process of using your word processor on your computer. On your computer, you double-click an icon on your desktop to 'load' the program. This double-click sends a signal to the operating system that you want to use this particular program. The operating system then makes a request to the CPU to retrieve a copy of the program from the computer disk. The CPU and operating system then find where on the disk this program resides and starts to copy the program code from the disk into the computer's memory*.

YES...if your name is bill gates If you have his permission, or you could just change your o.s. yourself from xp to vista or whatever.

Program code in a form suitable for direct execution by the central processor, i.e. code containing no symbolic references.

You go to the loading tab on the bottom where it has the little magnifying glass and the hundred percent, then you can click it once for 150 and twice for 100.
