The partitioning or division of a large hard drive into smaller units. A single, large Physical Drive can be partitioned into two or more smaller Logical Drives.
A drive recognised by the operating system with a unique identifier such as C or D. A single physical drive can act as several logical drives, each with its own identifier.
The internal division of a large hard disk into smaller units. One single physical drive may be organized into several logical drives for convenience; DOS supports up to 23 logical drives on a system. On a single-floppy system, the disk drive can function as both logical drive A and logical drive B, depending on the exact circumstances.
