Chapter 4, Problem 60E
Program Plan Intro
Bus:
Bus is a collection of wires which is connected to one or more subsystems within a same system. It has shared and common data path which is allowing parallel movement of bits.
It is differentiated into two types. Synchronous bus and asynchronous bus.
Synchronous bus:
This buses sends the information in form of blocks and frames. It is clocked and the transmission occurs only at clock ticks. There is no gap between the data while sending in the bus. The time interval is constant. It is expensive in cost and fast in transmission.
Asynchronous bus:
It sends a byte or character at a time. The control lines are coordinate with the operations and handshaking protocol is employed to effect the timing.

I need help writing pseudocode for calculating class score average by putting in 5 test scores, and showing the average from all 5 inputs and the GPA score.Starting with 3 functions outside of a main module. The functions are getScore(), getGPAPoint(Integer score), and getAverage(). Function getscore is an input for a grade as a class percentage. Function getGPAPoint will calculate the score into a GPA point and return as a float (values of 90-100 as 4.0, 80-89 as 3.0, 70-79 as 2.0, 60-69 as 1.0, and anything below 60 as 0.) Function averageGPA will finally make a call to both previous functions when the user inputs numbers 5 times that then calculates the average (add up all the scores, divide by 5) and the average grade alongside displaying the average GPA.
End result is a main module that makes a proper call to the averageGPA function and display its results. Need help with this!
