Answer: Both (a) and (c)
Explanation:
The correct answer is (d) Both (a) and (c).
The main job of a CPU (Central Processing Unit) is to carry out program instructions and process data and information. The CPU fetches program instructions from memory, decodes them to understand what operation needs to be performed, performs the operation using its Arithmetic Logic Unit (ALU), and stores the result back in memory.
In addition to executing program instructions, the CPU also processes data and information by performing mathematical calculations, logical operations, and data manipulations. It does so by accessing data stored in memory or registers, performing operations on it using the ALU, and storing the result back in memory or registers.
Storing data/information for future use is the role of memory devices such as RAM (Random Access Memory) and hard drives, and it is not the primary function of the CPU.
