The terms RAM or ROM are often used in connection with memory. However, the difference between the two terms is large.
RAM: explanation of the term
The difference between the two terms is expressed in Technology and form of use out of.
- Behind the abbreviation RAM the name is hidden Random Access Memory. It is a memory technology with random access to memory cells (like ROM).
- You can with this storage technology Read and write operations carry out. This is also the crucial difference between RAM and ROM.

- As a saving element come here Capacitors for use. When you turn off your PC, the power supply stops and the capacitors discharge. The data is therefore lost and this is why it is volatile memory.
ROM: Differences from RAM

- For example, ROM uses the BIOS in your PC. However, this technique is used in many areas of application rewritable flash memory replaced.
- Notice: Images of the ROM memory of games are also used to copy them digitally. These are used, for example, for Pokémon ROM hacks.
