Answer:

1. The CPU fetches from the memory the instruction

2. The CPU decodes the instruction

3. The CPU fetches the operands (if needed)

4. The CPU executes the instruction

5. The CPU writes back the result(s)

6. The CPU updates itself to fetch the next instruction (Jump to Step 1)

Explanation:

The instructions are saved in the memory, so they need to be in the processor to get a result. But before doing anything, the CPU must decode it to "understand" it. If the instruction contains any logic or arithmetic operations, the Arithmetic Logic Unit (ALU) will do that job. Then, the CPU executes the instruction and writes back to the memory the result. As the last step, the Program Counter is updated to the memory adress of the next instruction.

A network of Bennetton retail sales agents select the Bennetton designs that they feel will appeal to Bennetton retail customers
denpristay [2]

Answer:

It is an example of a matrix structure

Explanation:

The matrix structure is a structure in which jurisdiction, controls and duties are carried and uphold by a group of employees instead of just the manager.

In other words, employees have dual reporting relationships; they can give reports to the functional manager and they can also give reports to the product manager.

The Bennetton design selected by the network of Bennetton retail sales agents made activities to be easily coordinated because, they have collectively performed the duty as a unit and this is one of the advantages of this form of the matrix organizational structure.
