Expert Solution & Answer
Chapter 7, Problem 46SG
Explanation of Solution
Uses of interactive whiteboards and force-feedback game controllers:
Interactive whiteboard:
- An interactive whiteboard is like a dry-erase board. It is a touch-sensitive device that shows the image on a computer screen through a projector.
- A presenter operates a program by touching the whiteboard, clicking a remote control, drawing on or erasing the whiteboard with a special digital pen and eraser, or writing on a special tablet.
- The written notes on the interactive whiteboard can be saved directly on the computer.
- It is used in the classrooms, company meetings, and delivering presentations.
- For example, an interactive whiteboard is used in the classrooms as a teaching tool. The trainers and students can write on an interactive board that communicates wirelessly with the whiteboard...
Explanation of Solution
Tactile output:
- Some input devices such as mobile devices, smartphone, and mouse that are used to give instruction causes the software to perform a particular action.
- These input devices also operate as output devices when they include tactile output...

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
