==> bit
Claude E. Shannon first used the word bit in a 1948 paper. Shannon's bit is a portmanteau word for binary digit (or possibly binary digit). He attributed its origin to John W. Tukey.
==> byte — the term was coined by Werner Buchholz in 1956 during the early design phase for the IBM Stretch computer. It was coined by mutating the word bite so it would not be accidentally misspelled as bit. A byte is a small grouping of bits.
