Data Organization:I. Organizing Tracks by Sectors (Cont’d)
Advantage of 1: Each record can be retrieved from 1 sector.
Disadvantage of 1: Loss of Space with each sector ==> Internal Fragmentation
Advantage of 2: No internal fragmentation
Disadvantage of 2: 2 sectors may need to be accessed to retrieve a single record.
The use of clusters also leads to internal fragmentation.
