62. Processors of all computers, whether micro, mini or mainframe must have A. ALU B. Primary storage C. Control Unit D. All of the above E. None of the above
All computers, large and small, must have a central processing unit. As Figure 1 shows, the central processing unit consists of two parts, the control unit and the arithmetic/logic unit. The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data.
