In comparison to short-term memory, the storage capacity of long-term memory can last for days, months, years or for an entire lifetime. [6] Long term memory can still be forgotten so the information that is held here is constantly changing over time. [8] Long-term memory has three components.
In computing, a word is any processor design's natural unit of data. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits [a] in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architecture.
Research has suggested that long-term memory storage in humans may be maintained by DNA methylation, [35] and the 'prion' gene. [36] [37] Further research investigated the molecular basis for long-term memory. By 2015 it had become clear that long-term memory requires gene transcription activation and de novo protein synthesis. [38]
A representation of that rapidly decaying memory is moved to short-term memory. Short-term memory does not have a large capacity like sensory memory but holds information for seconds or minutes. The final storage is long-term memory, which has a very large capacity and is capable of holding information possibly for a lifetime. [2]
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
Previous research has found that people performed better on memory tests in the hours after they exercised, but many studies haven’t pinned down how long those perks last.

Neither holds information for long, but short-term memory is a simple store, while working memory allows it to be manipulated. [17] Short-term memory is part of working memory, but is not the same thing. Working memory refers to structures and processes used for temporarily storing and manipulating information.
