RAM or ROM - this is the difference

The terms RAM or ROM are often used in connection with memory. The difference between the two terms is huge. We explain what the two abbreviations mean.

Explanation of terms - RAM

The difference between the two terms is expressed in terms of technology and use:

• The name "Random Access Memory" is hidden behind the abbreviation "RAM". This is based on a memory technology with random access to memory cells (as with ROM).
• You can use this storage technology to perform read and write operations. That is also the crucial difference between RAM and ROM.
• For the most part, computer manufacturers use this technology in the form of "DRAM" for the RAM of your PC. Because this type of storage is faster than a hard drive.
• Capacitors are used as the storage element. If you switch off your PC, the power supply is cut off and the capacitors discharge. The data is therefore lost and it is therefore "volatile" memory.

ROM - these are the differences

• "ROM" stands for "Read only Memory". The memory is therefore only written or programmed once initially, after which you can only read from it. Here too you have random access to memory cells.
• For example, ROM uses the BIOS in your PC. However, this technology is being replaced by rewritable flash memory in many areas of application.
