Explanation:

ADD A, R7 is an example of register instructions. To understand this, we need to understand the following concepts:

• Register instructions: These are instructions that perform operations on registers. Registers are small, fast memory locations within the CPU that hold data for immediate processing. Examples of register instructions include ADD, SUBTRACT, LOAD, and STORE.

• ADD instruction: This instruction adds the contents of two operands and stores the result in the destination operand. In this case, the source operand is R7 and the destination operand is A.

• R7: R7 is a register that is being used as the source operand in this instruction. It contains a value that will be added to A.

• A: A is a register that is being used as the destination operand in this instruction. It will hold the result of the addition operation.

Therefore, ADD A, R7 is an instruction that adds the contents of R7 to A and stores the result in A. This is an example of a register instruction because it performs an operation on registers.
