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 ${\ displaystyle t \ in [0, T] \ colon}$

{\ displaystyle {\ text {Stored amount}} (T) = \ int _ {0} ^ {T} ({\ text {Inflow rate}} (t) - {\ text {Outflow rate}} (t)) \; \ mathrm {d} t + {\ text {Stored amount}} (0)}

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

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
