Answer the followings. Explain in detail.
a) Microprocessors normally use two methods to connect external devices: memory mapped or
port mapped I/O. Compare and contrast these two concepts.
b) Does Intel 8086 processor separate the I/O address space from the memory address space, or
not? Provide your answer clearly. What are the advantageous and disadventageous of such an
approach.

Write a program to use Math methods to calculate and display the followings: Prompts the user to enter an angle, in degrees, and then display the angle in radians and the Sine of the angle. Prompts the user to enter a positive integer and calculates the square root of the number. Computational thinking: Your program must check if it is a positive number. If a negative number is entered, it must ask for another number until the positive number is...
