Detailed explanation-1: -"16 bits can address 2^16 memory locations, each location is 8 bits. So we can address a 524288 bit (65536 octet) memory."
Detailed explanation-2: -Addressable memory is the maximum amount of memory which a particular computer can actually use. Adding any more memory than this is pointless as the computer will be unable to use it. Address bus width determines how much memory can be addressed.
Detailed explanation-3: -Word Size. The “word” size is the number of bits in the CPU’s internal registers. For example, a 64-bit computer uses 64-bit registers and can process 64 bits at one time.
Detailed explanation-4: -The bus is the mechanism by which the CPU communicates with memory and devices. A bus is, at a minimum, a collection of wires but it also defines a protocol by which the CPU, memory, and devices communicate. One of the major roles of the bus is to provide an interface to memory.
