communication protocols define format and order of messages sent and received among network entities, and actions taken on message transmission and receipt.
Internet Protocols
The Internet is powered by many layers of protocols. Examples of Internet protocols including
- IP: A protocol that uniquely identify devices using IP addresses and provides a routing strategy to send data to a destination IP address.
- TCP/UDP: Protocols that can transport packets of data from one device to another and check for errors along the way.
- TLS: A secure protocol for sending encrypted data so that attackers can’t view private information.
- HTTP & DNS: The protocols powering the World Wide Web, what the browser uses every time you load a webpage.
