Working with Disks, Drives and Folders

Disks and Drivers
A computer user disk drives to store information. Floppy disk drives, hard disk drives and CD-ROM drives are thew types of drives used to store information. Each idsk drive is identified by a name, which is called the drive name. a drive name can be any letter of the alphabet. The floppy disk drive is usually referred to as drive A.
You can compare a hard disk drive with that of a storage home. In a storage house, you can find partitions for storing different types of goods. The partition will be labeled according to the type of goods being stored in them. Similary, a hard disk drive can be divided into a number of separate sections, where each section acts like separate disk drive. This process of dividing the physical hard disk driveinot various logical sections for organization is called partitioning. Each section of the hard disk drive is called a partition.
Organizing Data
Consider this scenation. As a teacher, you handle subjects for different. If you were to write down the notes for all classes in the same notebook, it might be difficult to find class specific note when you needed the .you might have to search page by page to find the information you were looking for.
Similarly, if all the information on a computer were stored together, it would be difficult to find it every time you needed information. Hence, computers store data and information as files.files are computerized documents that store information in different forms, such as text andpictures. The bitmap images you created in paint and the presentations you created in powerpoint are examples of files. Each file stored on a computer has a name to identify it. This is called the file name. All files have two parts in their names: the primary name and the extension.
Primary name
This is the first part of the file name. it is the anme by which a file is identified.
Extension
The second part contains the extension of the file name. the identifies the type or family of the file.
An example of a file anme created in word is Lesson1.doc. Here, lesson1 is the primary name of the file and .doc is the extension, an example of a filename in paint is picture.bmp. Here, picture is the primary name and .bmp is the extension.
A file name can contain;
·  Letters
·  Numbers
·  Spaces
·  Special characters, such as the following:{ } [ ] , . ! $ % @.
Though you can use any name for your file, it is always a good practice to give meaningful anmes to your files. By just referring to a file name, you should be adle to know what is stored in the file.
Suppose you maintain the marks, attendance details and notes for each of your classes in separate files . If these files are scattered throughout various places, the the files may be difficult to locate. However, if  the files were stored in a common, organized location, hey would be easier to locate and mainitain. To organize files, windown XP provides the concept of folders. A folder acts as a storage comtainer for files. You can use a folder to stored files about a particul ar topic together in 
Common location. A folder icon   is yellow in color.
Imagine a library in which books on various subjects are shelved together. In such a situtino, searching for a book would be a difficult task . however, if the book for each subject were arranged on separate sheves, it would be easier to find a book. Similarly, if all the files on computer are stored are stored together without organization, they become difficult to locate. It is important to organize the file in folders.
