Disk storage units vary depending on whether the controller's read/write heads (by which data is read or is stored onto the disks) are fixed or movable and whether the disk pack itself is fixed or removable. The latter option permits greater hardware flexibility, given the ability to interchange disk packs (and associated files) at will, the safe storage of important packs as needed, and the copying of complete disk packs, given the presence of more than one storage unit. Disk storage units will also vary in functionality based on the time required to complete actual data transfer to and from disks to CPU primary memory.
Consider a retail store called The Clothing Store. As clothes are purchased wholesale from various manufacturers and arrive at The Clothing Store, the purchases must be recorded. Whether one uses pencil and paper or a computer, recording is a necessary function. 2. Storage Once the data has been recorded, it has to be stored for future use. All businesses and organisations have the need to place data in a safe place for future reference. The receiving records of The Clothing Store would be placed in a file with other past purchase documents.
Colour graphics terminals support a range of colours drawn from a 'palette' of available color options with the average number of selections ranging between eight and sixteen. Emulation refers, in this case, to the graphics terminals ability to display both text and graphics and to duplicate the standard functionality of a given type of VDT used with a computer system. Users are warned that manufacturer claims of emulation ability may in fact refer to only partial functionality at best. The ability to interface graphics terminals with other nongeneric devices such as pen plotters and graphics-oriented printers is a final factor that will influence potential terminal selection.
