Textbook Question
Chapter 2, Problem R1RQ
List five nonproprietary Internet applications and the application-layer protocols that they use.
Expert Solution & Answer
Program Plan Intro
Application Layer:
In the OSI (Open Systems Interconnection) model and TCP/IP (Transfer Control Protocol) model, the topmost layer is the Application layer. This layer is used for applications involving communication systems.
Explanation of Solution
Non-Proprietary Internet Applications:
Non-Proprietary Internet Applications are those internet applications which are not registered or protected as a trademark or brand name and they use certain application layer protocols.
Some of the Non-proprietary Internet applications along with the application layer protocols are mentioned below:
- The web:
- The web application is a client-server program in which the client runs in a web browser.
- The web application uses Hyper Text Transfer Protocol (HTTP) as application layer protocol.
- HTTP is an application protocol for distributive, collaborative, and hypermedia information systems.
- File Transfer:
- The File Transfer web application is an application that allows services to the users to share files over the web.
- The File Transfer web application uses the File Transfer Protocol (FTP) as application layer protocol.
- The FTP is a standard application layer tool in a computer network which is used to transfer files between client and server.
- Remote Login:
- The Remote login related applications are the applications that are used to control one computer from another computer by the use of a remote.
- The Remote login related application uses the Telecommunications Network (Telnet) as application layer protocol.
- Telnet is a bidirectional interactive text oriented communication facility which is used as a protocol on the internet by using a virtual terminal connection.
- E-mail:
- E-mail applications are used to send emails over the internet.
- The Simple Mail Transfer Protocol (SMTP) is used in E-mail related applications.
- The SMTP is only an application layer delivery protocol which is an internet standard for electronic mail transformation.
- Bit Torrent File Sharing:
- Bit Torrent file sharing application is a communication protocol that is used for peer to peer file sharing to share and distribute files and data over the internet.
- The Bit Torrent File sharing applications use Bit Torrent Protocol as application layer protocol.
- The Bit Torrent Protocol is a protocol that is used for distributing electronic files.

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
