Compact Disk Read-Only-Memory.Read-only-memory refers to a long-term memory solution. You have it in your computer under the form of a hard drive. Files and programs are stored in Read-Only-Memory then transferred to Random-Access-Memory (RAM, usually called "memory" by the average person) to work with.Compact disk is just the name of the technology used to store the data.
Compact Disk - Read-Only Memory
hard disk drive
RAM is like a computers short term memory, it stores temporary things like web pages you view or programs that are running. A Hard Disk is like long term memory, it stores photos and the programs you actually install.
Compact Disc ReWritable is a term used to refer to CDs that you can write data to multiple times.
The conversion of short term memory to long term memory is called memory consolidation.
Secondary Storage is storage that is used to store long term information, as it is not lost when a computer is powered off. The most common would be a Hard Disk Drive (HDD), followed by Digital Versatile Disk (DVD), Compact Disk (CD), Secure Digital (SD) Memory Cards, Flash Memory (USB Drives), Solid State Drives (SSD) and Floppy Disks
The term 'portable disk' refers to portable memory for a computer that is in the shape of a disk, such as a CD, DVD, or floppy disk. (On a floppy disk the disk part is on the inside)
State - Dependent Memory **
Two subsystems to long-term memory include semantic and episodic memory.

A magnetic read write-head moves a cross a spinning disk changing the polarity of tiny magnetic particles in the disk(s). This can then be read at a later date.
