What does the term 'Sector' refer to in data storage terminology?

The term 'Sector' refers specifically to a basic unit of storage on a disk. In the architecture of a hard drive or other storage devices, a sector is the smallest addressable unit of storage that can be read from or written to. Typically, each sector holds a fixed amount of data, commonly 512 bytes or more in modern systems, which allows the operating system and applications to efficiently manage and access data.

Understanding that a sector is a fundamental part of how data is organized on physical media helps clarify its role in data storage. It differs from a component of a file system, which involves higher-level organization of files and directories, or a type of memory, which could refer to various memory technologies that store data electronically. Additionally, a data recovery method refers to techniques used to retrieve lost or inaccessible data but does not define a sector itself.
