sector - Term Description

What is: sector

Description:
A logical segment of information on a particular track or the smallest addressable unit of storage on a disk. Tracks are divided into sectors, with each sector 512 bytes in size. Modern drives have more sectors per track towards the outside area of the disk, because the outside of a disk contains more surface area. This means the outer zones have a higher data transfer rate than the zones nearer the center of the drive. Modern drives have fewer and fewer sectors toward the center of the drive, allowing the disk to store more data.
