Answer 1

Explanation:

[A] In cache

[B] In secondary storage

[C] In CPU

[D] In primary memory

Option: [C]

In register addressing mode operands are stored in CPU. Data is moved from register to register.

please follow me and make my answer thanks

Answer 2

In register addressing modes operands are stored at the CPU.

• In the Immediate addressing Mode, the CPU acts register.
• An operand field contains the operand to be used in conjunction with an operation.
• It is determined in the given instruction set and the immediate-mode instructions help initialize registers to a constant value.
• An operand is an integer used as input to an operation.
• However, one operand for the Arithmetic Logical Unit remains in a register.
• On the other hand, the other operand may remain in a register or may remain part of the machine instruction during the execution.
• Thus, the result of the operation is put into a general-purpose register of the CPU.
• Some examples of Register Addressing Mode are MOVA, R5; MOVR2, etc.
