QUESTION 1
Sectors Control Unit Cylinders Program ALU Backing Store Internal Memory Track
In order to execute a ____________________ the computer must first load a file from its __________________ into its ____________________. The ___________________ then picks each instruction in turn, passing any mathematical or logical statements over to the ____________ until the entire sequence of instructions is completed.
Draw the process outlined above using any diagram you like, then copy the completed paragraph into your theory notebook.
At the end of this lesson, the completed answer will be posted. You may post any questions you like.

In order to execute a program the computer must first load a file from its backing store into its internal memory. The control unit then picks each instruction in turn, passing any mathematical or logical statements over to the ALU until the entire sequence of instructions is completed.
Algorithm
Input first number
Input second number
Input third number
Add first, second and third numbers : store as Total
Divide Total/3 : store as Average
Display Total and Average
Pseudocode
Input First
Input Second
Input Third
Total=First+Second+Third
Average=Total/3
Print Total, Average
