Answer all questions

1. Define PPP. What are its three components? Draw the diagram and explain PPP encapsulation frame.

Answer : PPP stands for the Point-to-Point Protocol, but even the standard that defines PPP immediately starts describing protocols that comprise it, which is why I consider it a protocol suite. At the highest level, the functions of PPP can be broken down into several components. Each of these encompasses a general class of PPP functionality, and is represented by either one protocol in the suite or a set of protocols.

Main PPP Components

The PPP standard itself describes three “main” components of PPP:

2. What do you mean by user datagram protocol? Draw and explain the diagram of UDP datagram format.

Answer: UDP (User Datagram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a

3. Explain in brief Ports and Sockets.

Answer: Ports

Each process that wants to communicate with another process identifies itself to the TCP/IP protocol suite by one or more ports. A port is a 16-bit number, used by the host-to-host protocol to identify to which higher-level protocol or application program (process) it must deliver incoming messages.

4. Give an overview of FTP. List the FTP operations and explain any two of them.

Answer: An Overview of the File Transfer Protocol

The File Transfer Protocol (FTP) was one of the first efforts to create a standard means of exchanging files over a TCP/IP network, so the FTP has been around since the 1970's.  The FTP was designed with as much flexibility as possible, so it could be used over networks other than TCP/IP, as well as being engineered to have the capability with exchanging files with a broad variety of machines.

5. Explain HTTP operations with necessary diagrams.

Answer: HTTP Operations

The HTTP category includes the following operations:

HTTP is a good example of a protocol demonstrating RESTful design principles. In fact, proponents of REST argue that it is precisely the RESTful qualities of HTTP that enabled the rapid expansion of the World Wide Web. In keeping with REST principles,

6. What is SNMP manager? Explain types of requests to the SNMP agent.

Answer: What is SNMP?

Simple Network Management Protocol (SNMP) is an application–layer protocol defined by the Internet Architecture Board (IAB) in RFC1157 for exchanging management information between network devices. It is a part of Transmission Control Protocol⁄Internet Protocol (TCP⁄IP) protocol suite.
