Answers:
Here is the pictorial representation of first two lines of your question.
0 78 31
Opcode(bits) Operand (24 bits)
1. 2exp 32 unique instructions are possible.
How?
Ex: if the Machine is of 3 bits. Then the following combination if possible out of those 3 bits
000
001
010
011
100
101
111
Now each of these combinations can be an instruction to the machine. Like 000 can be used to instruct the machine to write. 001 to move; 010 to load ...
