non-volatile storage
Học thuậtThân thiện
Definition
Noun: * Computer storage that retains data without continuous electrical power: A type of computer memory or storage device that preserves stored information even when the device is powered off or loses its main power source. This is a fundamental characteristic for long-term data retention.
Usage
This term is used to describe the permanent or persistent storage component of a computer system. It contrasts directly with "volatile storage" (like RAM), which loses its data when power is removed. * Hard disk drives and solid-state drives are common forms of non-volatile storage. * The firmware is saved in a non-volatile storage chip on the motherboard. * For archival purposes, data must be written to non-volatile storage.
Advanced Usage
- Technical Context: In enterprise computing, discussions about data integrity and system recovery often focus on ensuring critical data is committed to non-volatile storage.
- The database transaction was not completed until the write was confirmed to non-volatile storage.
- As a defining attribute: The term is often used to specify the key feature of a storage technology.
- The new memory chip promises the speed of RAM with the non-volatile storage properties of flash.
Variants and Related Words
- Non-volatile memory (NVM): A closely related term often used interchangeably, though it can more specifically refer to the integrated circuits (chips) used for this purpose, such as Flash memory, ROM, or MRAM.
- Persistent storage: A common synonym emphasizing that data persists over time and across sessions.
- Volatile storage: The direct antonym; storage that requires constant power to maintain data, such as Dynamic Random-Access Memory (DRAM).
Synonyms
- Persistent storage
- Permanent storage (in a technical, power-related context)
Antonyms
- Volatile storage
- Temporary memory
Noun
- computer storage that is not lost when the power is turned off
