- 40. ANSWERS The standard protocol for the Internet is TCP/IP (Transmission Control Protocol/Internet Protocol). The essential features of this protocol involve (1) Identifying sending and receive device and (2) reformatting information for transmission across the internet. Identification: Every computer on the internet has a unique numeric address called an IP address (Internet Protocol Address). Reformatting: Information sent or transmitted across the internet usually travel through numerous interconnected networks. Before the message is sent, it is reformatted or broken down into small part called packets.
