It is the total amount of storage space consumed on the disk. In Web Hosting, its the total amount of storage space you are using, HTML files, images, logs, etc.
In standard binary usage for memory a KB is 1024 bytes. In standard decimal usage for disk drives a KB is 1000 bytes. Confused yet?

disk driver
No a disk drive is neither input or output device, it is an optical disk drive (for CD/DVD's) and a disk drive (for hard drives) would be a storage device.
The main difference between the C-SCAN and SCAN algorithms for disk scheduling is how they handle requests that are located at the end of the disk. C-SCAN moves the disk arm to the other end of the disk after servicing the last request, while SCAN moves the arm back to the beginning of the disk. This difference affects the order in which requests are serviced and can impact the overall efficiency of the disk scheduling algorithm.
du is a command the reports on the Disk Usage of the filesystem.
GNOME Disk Usage Analyzer
It is called "Disk Usage Analyzer" , it's located under the "Applications" menu, inside the "Accessories" section.
I'm not sure what you are referring to by "disk management." There are many utilities to check disk usage, delete files, and manage space quotas.
df df - report file system disk space usage du du - estimate file space usage
The disk size is defined by the manufacturer. You can't store more information than the disk can hold, just like you can't store more water in a jar that it can hold.
A disk space analyzer is a software utility for the visualization of disk space usage by getting the size for each folder (including sub-folders) and files in a folder or drive.
It is used by administrators of a multi-user system to monitor events related to disk usage, so that quota management and archiving can be done.
edquota -u username
The advantage with a smaller number of sectors per cluster, is that you get more efficient usage (less wasted space) on the disk. The disadvantage is that the disk directory (or FAT) gets very large and may slow things down
First, navigate to your Applications folder. Once inside, open the Utilities folder. Inside you will find a program called "Activity Monitor." Launch this program. Towards the bottom of the program window, you will see options such as, CPU, System Memory, Disk Activity, Disk Usage, and Network. Click the "Disk Usage" option. From there you should be able to view how much space you have used, and how much space you have free. You can also select different disks from this interface.
