Storage
A store (from Latin spicarium ' grain store ', from spica ' ear of corn '), depending on the context also called warehouse , depot , filing , buffer , supply or reserve , is a place or a facility for storing material or immaterial ( data storage ) objects .
Basics
- Matter ( substances , raw materials , goods , goods , waste , ...),
- Energy ( heat , pressure , electrical energy , ...),
- Information ( data , knowledge , ...)
Storage tanks can be of natural origin or man-made.
In most cases, people are stored for a limited period of time with the intention or at least the option of removing what has been stored for use at a later point in time. Such often intermediate storage, buffer or storage memory designated serve to compensate for timing differences between inflow / supply and drainage / demand.
Storage for an indefinite or permanent period is less common. For such storage, the term (final) storage or storage is more common.
Theoretical foundations
The stored amount and thus the filling level of the storage tank results mathematically as a time integral over the difference between the inflow rate and the outflow rate in the time interval
If the storage capacity (i.e. the maximum possible fill level) is exceeded, an overflow may occur.
A memory is an important element in control engineering . It can be used for smoothing. In a system with several storage tanks of the same type, vibrations can occur.
Types of storage
Storage for matter
- Floor storage for the storage of goods
- Pantry or a storage container
- Attic , which is often used as a storage location
- Silo , tank farm
- Underground storage for the storage of natural gas / hydrogen / oil
- Gas storage
- Water storage (reservoir, reservoir), in the case of a hydroelectric power plant, the upper area of the dam
Storage for energy
- Energy storage in energy technology
- Heat storage of a thermodynamic system
- Pressure accumulator
Storage for information and other intangible goods
- Knowledge store , e.g. B. a library , archive or reference work .
-
Data storage in computer science and electronics as a place for storing digital information (see also storage hierarchy )
- RAM , a central part of computers
- Buffers , temporary storage areas
- Clipboard , buffer for copy and paste
