what is memory address?

Question:

Answer: It is the place where your memory lives.... just kidding 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. Virtual memory is an imaginary memory area supported by some operating systems (for example, Windows but not DOS) in conjunction with the hardware.
