GB is an acronym for gigabytes. Gigabytes is a unit of measurement used to quantify different capacities of certain components in a computer. Storage Memory. Hard drives also use the designation GB. It is not considered memory but the amount of information a hard drive can hold.
Memory is 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. See Tips to Fix a Slow Running Computer in the Quick Reference section of Webopedia.
