Auxiliary memory
Auxiliary memory, also known as auxiliary storage, secondary storage, secondary memory or external memory, is a non-volatile memory (does not lose stored data when the device is powered down) that is not directly accessible by the CPU, because it is not accessed via the input/output channels (it is an external device).

Btrfs
Btrfs (pronounced as "butter fuss", "better F S", "butter F S", "b-tree F S", or simply by spelling it out) is a file system based on the copy-on-write (COW) principle, initially designed at Oracle Corporation for use in Linux.

Bus (computing)
In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers.

Checksum
A checksum is a small-sized datum derived from a block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage.

Computer data storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media that are used to retain digital data.

Consistency (database systems)
Consistency in database systems refers to the requirement that any given database transaction must change affected data only in allowed ways.

Data corruption
Data corruption refers to errors in computer data that occur during writing, reading, storage, transmission, or processing, which introduce unintended changes to the original data.

Data deduplication
In computing, data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data.

Data management
Data management comprises all disciplines related to managing data as a valuable resource.
New!!: Data redundancy and Data management · See more »
Data scrubbing
Data scrubbing is an error correction technique that uses a background task to periodically inspect main memory or storage for errors, then correct detected errors using redundant data in the form of different checksums or copies of data.

Database normalization
Database normalization is the process of restructuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity.

Denormalization
Denormalization is a strategy used on a previously-normalized database to increase performance.

ECC memory
Error-correcting code memory (ECC memory) is a type of computer data storage that can detect and correct the most common kinds of internal data corruption.

Error detection and correction
In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels.

Field (computer science)
In computer science, data that has several parts, known as a record, can be divided into fields.

File system
In computing, a file system or filesystem controls how data is stored and retrieved.

Hard disk drive
A hard disk drive (HDD), hard disk, hard drive or fixed disk is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

Metadata
Metadata is "data that provides information about other data".

Redundancy (engineering)
In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.

Redundancy (information theory)
In Information theory, redundancy measures the fractional difference between the entropy of an ensemble, and its maximum possible value \log(|\mathcal_X|).

Relational database management system
A relational database management system (RDBMS) is a database management system (DBMS) based on the relational model invented by Edgar F. Codd at IBM's San Jose Research Laboratory.
