Ethernet was first implemented in 1976. Ethernet II (DIX) was released in 1978 by DEC, Intel, and Xerox. IEEE 802.3 standard was published in 1983. Both versions are widely used and almost identical
ARINC 429 is the most common data bus for commercial aircraft. Uses unidirectional transmission over twisted pairs at 12.5 or 100 Kbps. Developed by ARINC Corporation for aviation communications
Parity bit is added to binary code to detect errors. Ensures even or odd number of 1-bits in string. Even parity sets parity bit to 1 if odd number of 1s. Odd parity sets parity bit to 1 if even number of 1s
TCP was developed by Vint Cerf and Bob Kahn in 1974. TCP/IP suite includes TCP as one of the main protocols. TCP provides reliable, ordered delivery of byte streams between hosts
Error detection and correction enables reliable data delivery over unreliable channels. Error detection identifies transmission errors, correction reconstructs original data. Classical Hebrew Bible copyists used stich counting for accurate text reproduction
Ethernet was developed at Xerox PARC between 1973-1974 for Alto computers. Named after luminiferous aether, inspired by ALOHAnet. First commercial Ethernet introduced in 1980, standardized in 1983
