FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Each data in the computer’s memory will have a unique identification number, which will be the address of the memory. Modern computers are addressed by bytes which are assigned to memory addresses – binary numbers assigned to a random access memory (RAM) cell that holds up to one byte.

Detailed explanation-2: -Each Cell is uniquely identified by a binary number called as “ADDRESS”. For example, the Memory Chip configuration is represented as ‘64 K x 8′ as shown in the figure below. Now we can clearly state the difference between Byte Addressable Memory & Word Addressable Memory.

Detailed explanation-3: -An address in main memory is called a location or physical address. The set of such locations is called the memory space, which consists of the actual main memory locations directly addressable for processing.

Detailed explanation-4: -Memory Addresses Memories consist of a number of cells (or locations) each of which can store a piece of information. Each cell has a number, called its address, by which programs can refer to it. If a memory has n cells, they will have addresses 0 to n − 1. All cells in a memory contain the same number of bits.

Detailed explanation-5: -Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers. Memory location in a stored-program computer holds a binary number or decimal number of some sort.
