FILE LOCK Meaning and
Definition
-
File lock refers to a mechanism employed in computer operating systems and software applications that restricts access to a particular file, preventing simultaneous modifications or deletions by multiple users or processes. It is a security feature primarily designed to ensure data integrity and prevent conflicts when multiple users need to interact with the same file simultaneously.
A file lock can be applied in two ways: on a read-level or on a write-level. The read-level lock, or shared lock, allows multiple users or processes to access the file in read-only mode concurrently. It prohibits write operations until all read locks are released. On the other hand, a write-level lock, or exclusive lock, grants exclusive access to a single user or process, preventing others from both reading and writing the file until the lock is released.
File locking is commonly employed in multi-user systems, such as database management systems and distributed file systems, where concurrent access to files is required. It prevents data corruption, lost updates, and other conflicts that may arise when multiple users or processes try to modify or delete the same file simultaneously.
File locking can either be implemented through software or supported by the operating system. The mechanism uses special lock files or data structures that store information about the locking process, allowing different users or processes to coordinate their access to the file effectively.

Etymology of FILE LOCK
The word "file lock" is a compound term that combines two words: "file" and "lock".
- "File" comes from the Old English "fȳlan", which means "to put documents on record". It evolved from the Latin word "fīlum", which refers to a thread or string used to secure or tie things together.
- "Lock" comes from the Old English "loc", which originated from the Proto-Germanic word "lukkan", meaning "to close or fasten". It indicates a device or mechanism used to secure or restrict access to something.
Therefore, the etymology of "file lock" essentially refers to the act of securely closing or restricting access to a document or file.
