(second semester Lecture 1 : Computer Preparing (Partitioning

What is a partition or volume?
The hard drive is an important part of computer parts, a storage device that provides always saving data even after the power supply interrupted. A partition is an area of a hard disk that can be formatted and assigned a drive letter, (The terms volume and partition are often used interchangeably). Your system partition is typically labeled with the letter C. Letters A and B are reserved for removable drives or floppy disk drives. Some computers have hard disks that are partitioned as a single partition, so your whole hard disk is represented by the letter C. Other computers might have an additional partition that contains recovery tools, in case the information on your C partition becomes damaged or unusable.
How do I create more partitions?
To create a partition or more partitions on a hard disk, you must be logged in as an administrator, and there must be either:
• unallocated disk space(unformatted space that is not part of an existing partition or volume) or
• free space within an extended partition on the hard disk.
If there is no unallocated disk space, you can create some by shrinking an existing partition to create unallocated space.
