Part A
What is the definition of computer organization.
Answer
Computer organization refers to the operational units of a computer system and their interconnections that realize the architectural specifications. It focuses on the hardware details, such as control signals, memory technology, and peripheral interfaces, that make the computer function.
Explain indirect Address.
Answer
In indirect addressing, the instruction specifies an address that contains the effective address of the operand rather than the operand itself. This requires two memory accesses: the first to fetch the address from memory, and the second to fetch the actual data from the pointed address.
