The Flow

Step 1

• The information goes into the computer through an input device(mouse, keyboard, etc.).

Step 2

• The information then goes to the micro processor to be fetched, decoded, and executed.

Fetch

• Transistors fetch the information.

Decode

• The transistors then decodes the fetched information and calls for which operation is called for.

Execute

• The command then gets executed. Then it goes to memory.

Step 3

• The executed information then goes to memory.

Step 3(continued)

• And to an output device(monitor, printer) for the command to be executed .
