Operating system (OS) is the main program that controls how your computer system functions. The OS manages the computer hardware, including the processor (CPU) , memory, and storage devices as well as peripheral devices such as the monitor and printer. In most cases, the operating system is installed and resides on the computer’s hard disk. On handheld computers and many mobile devices, the OS may reside on a ROM chip. Three popular personal computer operating systems are : 1. Windows 7 2. Linux 3. Mac OS X

Disk Cleanup is a Windows utility that cleans unnecessary files from your hard drive :

• files that accumulated in the Recycle Bin • temporary files

files created by Windows to store data temporarily when a program is running

• temporary Internet files Web pages stored in your hard drive for quick viewing

If these files not deleted periodically, these unnecessary files can deter efficient operating performance.

Disk Defragmenter is a utility that reorganizes the files and unused space on a computer’s hard disk so the operating system accesses data more quickly and program runs faster. Fragmentation (files stored in scattered sectors) slows down disk access and thus the performance of the entire computer. You should check several time a year to determine whether your drive needs to be defragmented. Defragmenting the disk, or reorganizing it so the files are stored in contiguous sector.

COPY AND PASTE

OBJECT LINKING & EMBEDDING (OLE)

Data sharing is the practice of distributing or providing access to digitally stored information such as multimedia (audio, image, video, text, animation) or documents. It may be implemented through a variety of ways :

Copy-and-Paste refers to the popular, simple method of reproducing data from a source to a destination. Copying often takes place in graphical user interface systems through use of the key-combinations CTR+C or by using a toolbar button. Once data has been copied into the memory area referred as the clipboard, we may paste the contents of the clipboard into a destination using the key combinations CTR+V or other methods dependent on the system.

COPY AND PASTE

OBJECT LINKING & EMBEDDING

Object linking and embedding is a way to use information from one application in another application. Both linking and embedding insert information from one document into another document. Also, both linked and embedded OLE objects can be edited from within the destination application. The main differences between linked objects and embedded objects are where you store them and how you update them, if need be, after you place them in the target file

OBJECT LINKING OBJECT EMBEDDING

An embedded object is created in an application in a separate source file too, but then it is inserted into the target file, becoming part of that file. If you make a change to the original source file, the change will NOT show up in the target file.

A linked object is created and stored in a separate source file, and then it is linked to the target file. Because the two files are linked, when you make changes to one file, the changes appear in both the source and target files. When you link your document to some external data object, your document records a pointer to the source of that data. If the source changes, your document will change accordingly.
