CPU processing, memory and disk storage are all subject to some variation of this law. As well, hardware innovations such as multi-core architecture, NAND flash memory, parallel servers, and increased memory processing capability, have contributed to the technical and economic feasibility of in-memory approaches.
An in-memory database (IMDb, or main memory database system (MMDB) or memory resident database) is a database management system that primarily relies on main memory for computer data storage. It is contrasted with database management systems that employ a disk storage mechanism. In-memory databases are faster than disk-optimized databases ...
Holographic storage can utilize the whole volume of the storage medium, unlike optical disc storage, which is limited to a small number of surface layers. Holographic storage would be non-volatile, sequential-access, and either write-once or read/write storage. It might be used for secondary and off-line storage. See Holographic Versatile Disc ...
Disk storage is now used in both computer storage and consumer electronic storage, e.g., audio CDs and video discs (VCD, DVD and Blu-ray). Data on modern disks is stored in fixed length blocks, usually called sectors and varying in length from a few hundred to many thousands of bytes. Gross disk drive capacity is simply the number of disk ...
Although sharing a similar name, heap files are widely different from in-memory heaps. In-memory heaps are ordered, as opposed to heap files. Simplest and most basic method insert efficient, with new records added at the end of the file, providing chronological order; retrieval efficient when the handle to the memory is the address of the memory
Data storage is the recording (storing) of information in a storage medium. Handwriting , phonographic recording, magnetic tape , and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage.
