Memory mapping

In computer technology, the English term memory mapping refers to the so-called memory display. There is memory mapped I / O and caching of a data record. With memory mapped I / O, the external memory of a component on the motherboard (e.g. graphics card ) is faded into the main memory ("mapped") to enable faster access to it (instead of interface access ). When the file is faded into the main memory, an area of ​​the file is faded into a memory area of ​​a running process . Writing to the memory area causes indirect write access to the file.
