Expert Solution & Answer
Chapter 0, Problem 12SI
Explanation of Solution
To choose the era of history to live with the help of Time machine:
I would like to live in that period of history in which there is no deforestation, no pollution and war.
I would cherish to live in an era where people connect together by spending time together rather than on social platforms, and in an era where there is no overexploitation of natural resources.
I would like to live where there is less population, love between humans and the environment is conducive for health.
The technologies that I would like to take back from modern times:
- Medical treatment: I would like to take modern medical technologies, the medicines and surgical equipments and labs that help humans to save lives.
- Smartphones: I would like to use smartphones for location tracking and for better communication.
- Computers and internet: I would like to have information shared across globally within a click. Therefore, I would like to take computer technologies.
Independent choice of technologies:
“No”, the choice of one technology cannot be taken without taking others because the growth of technology is always related to each other. One technology supports the other.
The technology used in smartphones is supported by growth of semiconductor industry, batteries and display screens.
The medical technology thrives on industries to make equipment, to design surgical equipment and to set up factories to make medicines.
Therefore, one technology can’t be taken without taking the others.
There is a very thin line of separation between the technologies since each technology leads to development of other technology.
“Yes”, it is somewhat consistent to accept modern treatment while protesting against global warming. The deforestation can be stopped; the over-exploitation of natural resources can be regulated. New and modern equipment can be designed in such a way that they are energy efficient and thrive on green technologies.

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.
