Chapter 5, Problem 1FWD
Explanation of Solution
Web Content Accessibility Guidelines (WCAG):
The guidelines for web accessing have been developed through the W3C process. The purpose of these guidelines is to provide the accessibility of web contents like text, images, structure, presentation, and so on.
Usage of color and images that was mentioned in “WCAG 2.0”:
Color element is used for conveying the information interactively. All web elements use color for their text, background, or other styling purpose. Some of them are mentioned below:
- Ensuring the color in data, backgrounds, or other contents is to indicate the information.
- Ensuring the color within an image to convey the information.
- Images are used to provide picture in the web page. The user can modify the properties like border, size, and alternative text for an image.
Web page:
The following code is used to demonstrate “WCAG” with color and image element:

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:

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.
