Device Category
Device is the educational section of online Help. It describes the function and purpose of the highlighted device in the Device Groups.
For example, the following information appears when you select Device for Diskette in the Device Groups list:
Diskette drive A:
The diskette disk drive device reads and writes data to and from diskettes. Diskettes are flexible
recording media, sometimes contained in hard shells. Diskette recording capacities are small and
access times are slow relative to hard disk drives, but they provide a convenient means of storing
and transferring data.
Test Category
Test provides a thorough explanation of the subtest for each selected device group. For example, the following description is provided for the
Diskette Drive Seek Test:
Diskette drive A: - Diskette Drive Seek Test
This test verifies the drive's ability to position its read/write heads. The test operates in two
passes: first, seeking from the beginning to ending cylinders inclusively, and second, seeking
alternately from the beginning to ending cylinders with convergence towards the middle.
