Q. What is Instruction Register?

Instruction Register (IR): Here instructions are loaded before execution. Comments on figure above are as below:

All representations are in decimals. (In real machines the representations are in Binary).
Number of Memory Locations = 16
Size of every memory location = 16 bits = 2 Bytes (Compare with contemporary machines word size of 16, 32, 64 bits)
So size of this sample memory = 16 words (Compare it with actual memory) size that is 128 MB, 256 MB, 512 MB, or more).
In the diagram MAR is pointing to location 10.
Last operation carried out was 'read memory location 10' that is 65 in this. So the Contents of MBR is also 65.
