memory address

number that indicates the location of information within the memory of a computer

In computer science, a memory address is a unique identifier for a memory location at which a CPU or other device can store a piece of data for later retrieval. In modern byte-addressable computers, each address identifies a single byte of storage; data too large to be stored in a single byte may reside in multiple bytes occupying a sequence of consecutive addresses. Some microprocessors were designed to be word-addressable, so that the typical storage unit was actually larger than a byte. Examples include the Texas Instruments TMS9900 and the National Semiconductor IMP-16, both of which used 16 bit words.
