The geometry of a hard drive consists of many different sections. Which parts of the hard drive geometry are grouped together into a cluster?
A) Tracks
B) Sectors
C) Cylinders
D) Heads
The answer: B) Sectors
A cluster is a group of sectors, and each sector is usually 512 bytes. Instead of expecting the operating system to keep track of every single sector, the hard drive clusters are usually grouped together. Clusters often contain anywhere between 4 and 64 sectors.
