= Vint Cerf
{c}
<Vint Cerf> contributed to the architecture and protocols of the <Internet>, including the design of <TCP> and <IP>. His Internet Society biography identifies this internetworking contribution.https://www.internethalloffame.org/inductee/vint-cerf/[Inductee biography, TCP/IP co-design]{ref} An early primary document is his 1969 RFC 20, which records an <ASCII> representation for network interchange.<ASCII format for Network Interchange by Vint Cerf>[RFC 20, byline and code table]{ref}
Agreeing on transmitted <bits> is only one part of communication: endpoints must also agree on how those bits encode characters. The RFC's seven-bit table and placement within an eight-bit byte make that convention explicit. This small document illustrates the same broad interoperability problem encountered in network protocols: independent implementations need common meanings as well as a connection.
