Internal storage areas in the computer. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk.
Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information.
Listed here are some of the terminology used in conjunction to memory, and it's properties.
Virtual Channel Memory A memory architecture that is a variant of SDRAM, that has not been seen widespread adaptation
Virtual Memory This is system memory that is simulated by the hard drive When all the RAM is being used (for example if there are many programs open at the same time) the computer will swap data to the hard drive and back to give the impression that there is slightly more memory
VRAM Video RAM DRAM with an on-board serial register/serial access memory designed for video applications
