Operating Systems

there are many type of open source operating system like Linux which provide their source code so you may edit it according to your need.but window is not give their source code.

Android mobile OS is a Linux-based open sourced operating system from Google. It's mainly in touchscreen devices (smartphones, tablets), but is venturing into the laptop space.

Installable device drivers allow the OS to support new devices without updating the OS.

Operating System's kernel

yes

It doesn't run on Windows or Mac if that's what you're asking. It's it's own operating system, just like everything that isn't a computer.

Linux

I use Systemax for working with my website... I've had better luck performance wise with Systemax than I did with Dell.

System View is a snap-in that lets you view what the computer is doing in real time.

GUI (graphical user interface)

Front office managemant uses a human resources approach to cover the uniqe management and operational challenges in the front offices of today's hotels and lodging facilities.In adresses the impact of the recession on the hotel businesss and discusses the impact of social media and guest room technology on the hotel business and how the internet is the single most important travel planning and distribution channel in hospitality.There is also new and updated information on environment and sustainability issues.

Utility Software

Operating systems for tablets and smartphones are very similar. The tablets are usually able to handle more processing, so they can handle some apps that a phone cannot.

Distributed computing:

Following are the proper operating systems for implementing distributed computing.

Multiprocessor systems: A multiprocessor system is simply a computer that has more than one CPU on its motherboard. If the operating system is built to take advantage of this, it can run different processes (or different threads belonging to the same process) on different CPUs. Over the years, many different multiprocessing options have been explored for use in distributed computing. Intel CPUs from the late Pentium 4 era (Northwood and Prescott cores) employed a technology called Hyperthreading that allowed more than one thread (usually two) to run on the same CPU. The most recent Sun UltraSPARC T1, AMD Athlog 64 X2, AMD Athlon FX, Intel Pentium D and Intel Conroe processors feature multiple processor cores to also increase the number of concurrent threads they can run.

Multicomputer Systems: A multicomputer system is a system made up of several independent computers interconnected by a telecommunications network. Multicomputer systems can be homogeneous or heterogeneous: A homogeneous distributed system is one where all CPUs are similar and are connected by a single type of network. They are often used for parallel computing. A heterogeneous distributed system is made up of different kinds of computers, possibly with vastly differing memory sizes, processing power and even basic underlying architecture. They are in widespread use today, with many companies adopting this architecture due to the speed with which hardware goes obsolete and the cost of upgrading a whole system simultaneously.

Multimedia Development:

Multimedia development requires powerful development platforms running with operating systems that are suited to the development task. Macintosh OS is the suitable for multimedia development. On the Macintosh side, Apple's absolute control results in greater ease for users who must integrate additional functionality into this environment. On the downside, a smaller installed base has given rise to fewer hardware and software options that often bring higher prices than are usually seen on PC-compatible products.

Database management:

Database management system is easily operable with most of the OS. Database management is supported for windows, Linux, Unix platform etc. Several operating system services are examined with a view toward their applicability to support of database management, and interprocess communication; and consistency control. Most of the OS meets with above all services. So database management can be done with most of the OS.

You would use an operating system on your pc/laptop to run all the processes and manage all the hardware and resources contained in your unit, also to manage the applications you have installed there.. whereas you would have system software or application software to sit on top of your OS to manage you day to day emailing, word processing, faxing, photos, music downloads etc...

To set up Mail to connect to your Exchange 2007 account in Mac OS X 10.6 (Snow Leopard) open Mail's Preferences and select the Accounts section. Click the + button to add a new account. Enter your email address and password for your exchange account. Mail will then automatically set up the account and will offer you the option to also set up Address Book and iCal with your account info.

Because, if you wanted to get some software, for example, you need to make sure that it will be compatible with your Operating system and how it reads programs and things, therefore you need to know which Operating System you have.

Also, if you need to fix something or you want to change something in your settings; Knowing your OS will help, as you can specify it in Google when looking for help to do the task, which will narrow down the results to give you the best answer.

All the OS are compatible with dual OS.but here i will suggest you keep it parallel.
