Chapter 4, Problem 11RQ
Program Plan Intro
Transmission Control Protocol (TCP):
- TCP is an internet protocol used for exchanging of data between the sender and the receiver. It is a secured protocol for transferring the data.
- When the sender sends data to the receiver, he/she waits for the acknowledgement from the receiver.
- If acknowledgement is received then the next data packet will be sent and the process continues till all the data packets are sent.
- If acknowledgement is not received then the receiver is assumed as hacker or intruder and the connection will be removed.
User Datagram Protocol (UDP):
- User datagram protocol is a connectionless protocol.
- The protocols used in UDP cannot establish the connection for data communication.
- It is one of the communication protocol suites used for transferring small messages termed as datagram.
- Alternative for TCP is UDP, but the data transfer speed of UDP is higher than TCP because there is no acknowledgment and error-checking.
- Checksum and port number are the two services provided by the UDP.
- There is no guarantee for data delivery and duplication of data.
- It doesn’t provide a reliable service.
