Features of Memory
Memory can be accessed through four modes of memory. The performance of memory is generally divided into three parts.
Memory Organization
•The memory unit consists of binary cells and two registers named MAR (Memory Address Register) & MDR (Memory Data Register). •The MAR holds the address of the word [each memory location stores 32 bits (8 hexadecimal digits) which we call a word] in the memory to be accessed. •The data read from the memory or […]
ASCII (American Standard Code for Information Interchange)
•ASCII is the most often used code to represent information. •A binary field of 7 bits to represent each character, so the total of 27 = 128 unique characters can be represented by 7 bits. •But some systems use an expanded version of the ASCII code with 8 bits (256 characters). •To represents a typed […]
