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.

2. 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

3. network devices. It is a part of Transmission Control Protocol⁄Internet Protocol (TCP⁄IP) protocol
suite.
