Final answer:
Packets use various protocols in network communication including IP, TCP, UDP, and ICMP.
Step-by-step explanation:
The packets use various protocols depending on the layers of the network stack they operate at. Some of the commonly used protocols in packet communication include:
- Internet Protocol (IP): This protocol is responsible for routing packets across networks, ensuring their delivery to the correct destination.
- Transmission Control Protocol (TCP): TCP is a reliable and connection-oriented protocol used for transmitting the packets over the internet. It ensures that the packets are delivered in order and without errors.
- User Datagram Protocol (UDP): UDP is a simple and less reliable protocol that allows packets to be sent without establishing a connection. It is often used for time-sensitive applications like streaming media or online gaming.
- Internet Control Message Protocol (ICMP): ICMP is used for error reporting, diagnosing network issues, and providing feedback on packet delivery.
These are just a few examples of the protocols used in packet communication, and there are many more protocols that operate at different layers of the network stack.
