The process of transferring data from memory to a storage medium is called writing. This process is done by a storage device, which is any computing hardware that is capable of recording to and extracting objects from a storage medium.
When a storage device writes to a storage medium, it functions as an output source. In computing, memory refers to motherboard chips, which hold instructions and data temporarily for processing when the computer is turned on.
A storage medium is any physical material that holds data. Examples of storage media include microfilm, floppy disks, CD-ROMs, DVD-ROMs and cassette tapes. A DVD-ROM, which stands for digital video disc read-only memory, is capable of high-capacity storage, ranging from 4.7 to 17 gigabytes.
