I suggest you start by reading a good site on Grid computing. Personally I recommend Gridipedia. For example, as well as a good introduction, you can find read up on the business case behind it and see iti in action in the case study library they have: www.gridipedia.com
And example of centralised computing is IMB and Google's cloud computing service.
The one example of the earliest computing device is the "abacus".

In computing, a system call is the mechanism used by an application program to request service from the operating system. Operating systems contain sets of routines for performing various low-level operations. For example, all operating systems have a routine for creating a directory. If you want to execute an operating system routine from a program, request to the system call is required to be generated.

There are several cloud computing software packages available and the one that is best for you will depend largely on the set up of your computer. For example, the operating software, processing speed and available hard drive space you have may limit the soft ware packages that will work for you. Companies like Amazon, Dell, and Microsoft all offer cloud computing tools.
Normally an operating room nurse, OR nurse, assigned that particular duty. Other OR nurses might be responsible for example of monitoring electronic life support devices.
A good example of cloud computing is need for more data storage. All devices have a maximum amount of data they can receive. Cloud computing allows you to expand your amount of storage. Also it benefits you by allowing for email on the go.

The term grid computing refers to collecting computer resources from multiple locations to reach common goals. A popular example of grid computing is the SETI project. You can get more information about grid computing at the Wikipedia.
Mounting takes place in order to allow a computer to read a storage device. For example you must mount an ISO image within the operating system before you can access it's contents.
Linux is the example of the latest open source operating system.
is linux a disk operating system
This is normally the raw computing power available. Example: I can say that with all of the computing resources man kind has ever made (at this moment) we can not simulate any human from birth to death.
Opportunities for hardwarre and software upgrade can be identified using a number of monitoring tools. In a Windows based environment moniting tools such as Performance monitor can be used to indentify upgrade opportunities by observing threshold counters to see if they exceed their maximum limit enforced by the operating system. For example if the processor utilization exceeds 90 percent as identified by performance monitor, this would signal an opportunity for upgrading the processor because it would no longer be efficient to multask operations such as opening many different programs at once on a computer. Other monitoring tools like Task Manager, Event Viewer and Device Manager can be used to monitor applications and hardware components of a computer system to identify opportunities for upgrade.
The easiest example of how cloud computing works is the Kindle e-reader. As for how the application works it is an off site vendor who stores all your information and software and you use the internet to access it.
Linux is a good example.
