Define the hard disk or hard disk drive, which are a form of magnetic storage medium. The major medium for storing software applications and information is now hard drives. Explain why occasionally the phrase fixed disk is used to refer to a hard disk placed inside a system unit. Make a distinction between longitudinal and perpendicular recording. What is the average storage capacity of hard drives in personal computers today? Since the birth of personal computers, have hard disk capacity increased significantly? Explain why formatting disks is necessary. Describe the three processes required in formatting a hard drive. Physical or low-level formatting should be distinguished from logical or high-level formatting. Provide definitions for partitioning, volume, file system, and block. Describe how a disk's storage capacity is decided. Describe the table formed in sector 0 of the first disk sector. What does "file system" mean? Comparing the different file systems.
