2. IP- Internet Protocol

3. UDP- User Datagram Protocol

4. HTTP- Hyper Text Transfer Protocol

5. HTTPS- Hyper Text Transfer Protocol Secure

6. SMTP- Simple Mail Transfer Protocol

7. FTP- File Transfer Protocol

8 PPP- Point to Point Protocol

9. POP3- Post Office  Protocol Version 3

So let us understand one by one about each of the protocols in detail:

1. TCP & IP

  The Transmission Control Protocol divides

  a message into series of packets and send the

  packets from source to destination.after 

  reaching the destination the packets again

  get reassembled.  Internet Protocol is used

  with TCP to send message to specified

  destination using  the IP address of the 

  nodes .                                           

         

2.UDP:

This is a communication protocol which is

a part of Internet Protocol Suite. It is a 

connectionless protocol.The main thing

that differentiate it from TCP is that

it is used to send message whithout any

checks and acknowledgement so it is

an unreliable protocol.

3.HTTP & HTTPS :

such as files.It is a standard Internet Protocol.
 

 

5.PPP:

 PPP  or Point to Point Protocol enables 

 transmission of traffic over  single channel

telephone connection.It provides dial up

connectivity to the Internet .

 

6.POP3:

 POP3 of Post Office Protocol Version3

 is used to store email message and download

 it for the reciever. alternatively it is used

 for storing email messages.
