Quizplus · Accepted Answer

The control unit sequentially accesses program instructions, decodes them, and controls the flow of data. It is a part of the CPU (central processing unit). Option A is incorrect because ALU (arithmetic logic unit) performs arithmetic and logical operations, but it does not control the flow of data. Option B is incorrect because DBA (database administrator) is not a component of a computer system. Option D is incorrect because the control unit is a part of the CPU, not the DBA.
