About CUI

13. The Graphical User Interface or GUI is the technological interface most of us are familiar with. There was a time when
you told a computer what to do through text commands (before that it was an index card with holes punched in it
called a “punch card”).
As you might imagine a point and click approach to computing provided a lot of benefits over a text-based approach.

About File allocation

28. A track is also a data storage ring on a computer floppy diskette or hard drive that is capable of storing information.
The illustration to the right shows how a track goes all around the platter, as well as how it is used to help locate and
retrieve information from a disk or diskette.
About track

29. In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a
fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs
and DVD-ROMs. ... The sector is the minimum storage unit of a hard drive.
About sector

30. Sectors and Clusters. Each track is divided into sections called sectors. A sector is the smallest physical storage unit
on the disk. The data size of a sector is always a power of two, and is almost always either 512 or 4096 bytes
