Chapter 2, Problem R1RQ

List five nonproprietary Internet applications and the application-layer protocols that they use.

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.
