Chapter 4.8, Problem 4.8ARQ
Explanation of Solution
Usage of email:
The “email” is an electronic mail; this term is new to all at that time for past 15 years. Because, many people know only newspaper, books, letter, and so on.
- Electronic mail is way of exchanging the messages among the people through the electronic devices.
- In early stage, the format of the email system needs the sender and recipient to be online at same time.
- But, nowadays the system of email is based on store and forward model which is fast-forward process.
- Email can be received within a seconds after it’s sent.
- It can be checked during break time, while driving in traffic, and so on.
- The process of exchanging digital data between one or more recipient is commonly referred to as email.
- It is provided by different service providing companies such as Google, Yahoo, and Microsoft.
- Email service provider such as Gmail stores the mails of everyone in its Google network servers.
- When a person accesses the email account, the browser downloads the content of the mail to the computer or mobile device.
- The person need not worry about the location of the computer; he/she can access their email account from any location.
Hardware and software might change the life:
The recent development of hardware and software has changed each and everyone life.
- The hardware and software development helps to people always linking, communicating, and playing.
- Internet of Things (IoT) will permits to frequently connect to more devices.
- Internet of Things is a design which objects are linked with internet for interaction purposes...

•
Your program will service a disk with 300 cylinders numbered 0 to 299.
•
•
•
•
The program will service the requests (a list of 20 cylinder numbers) given in the file
request.bin.
This file contains (4 byte) integer values representing requests ranging from 0-299.
Your program will take the initial position of the disk head as the first command line
argument and the direction of the head as the second command line argument.
It will then output the requests in the order in which they are serviced, and the total
amount of head movements required by each algorithm.
In particular, your program needs to do the following:
Your program should take two command line arguments
a) First command line argument - initial position of the disk head (an integer value)
b) Second command line…

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: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…arrow_forwardShow the correct stereochemistry when needed!! mechanism: mechanism: Show the correct stereochemistry when needed!!

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. Request for a contiguous block of memory 2. Release of a contiguous block of memory 3. Compact unused holes of memory into one single block 4.…arrow_forward
