A protocol is a set of rules and standards that define how devices on a network communicate with each other. These rules ensure consistent and efficient data exchange.
- IP Protocol
- Transmission Control Protocol (TCP)
- ARP
- Address Resolution Protocol
- Communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address.
- ICMP
