April’s computer is acting strange. She keeps trying to find information that she worked on yesterday, but the computer keeps displaying the incorrect information. She thinks the problem is with the memory of the hardware. Where does April think the problem is?
  1. Central Access Unit
  2. System Access Unit
  3. Central Processing Unit
  4. System Processing Unit
Explanation
Answer: C - When the incorrect information is being displayed and the memory seems out of order, the problem is within the central processing unit (CPU). The CPU is the brain of a computer. The CPU fetches instructions from the memory and executes them. Although a CPU is a piece of hardware, it has its own instruction sets, provided by the operating system, that are necessary to carry out its task. Each CPE type has a specific architecture and set of instructions that it can carry out. The operating system must be designed to with within the CPE architecture.
