Many cartridges and cassettes have the supply and take-up reels built into the same case. Now we will take a general tour of the hardware needed for input, processing, output, and storage. In fact, for many years supercomputer customers were an exclusive group: agencies of the federal government. With the help of a computer, authorized people can locate and access data quickly.
Finding track zero[ edit ] Before a disk can be accessed, the drive needs to synchronize its head position with the disk tracks. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. The dimensions of the disk shell are not quite square: its width is slightly less than its depth, so that it is impossible to insert the disk into a drive slot sideways i.

These major categories are word processing including desktop publishingspreadsheets, database management, graphics, and communications.
The group of connected disks operates as if it were just one large disk, but it speeds up reading and writing by having multiple access paths. Secondary storage consists of devices, such as diskettes, which can store data and programs outside the computer itself.
A little study shows that the case really isn't square: it's rectangular, so you can't insert a longer side. Some errors are soft and can be resolved by automatically re-trying the read operation; other errors are permanent and the disk controller will signal a failure to the operating system if multiple attempts to read the data still fail.
