Historical Uses
Prior to file comparison, machines existed to compare magnetic tapes or punch cards. The IBM 519 Card Reproducer could determine whether a deck of punched cards were equivalent. In 1957, John Van Gardner developed a system to compare the check sums of loaded sections of Fortran programs to debug compilation problems on the IBM 704.

Famous quotes containing the word historical:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“Some minds are as little logical or argumentative as nature; they can offer no reason or “guess,” but they exhibit the solemn and incontrovertible fact. If a historical question arises, they cause the tombs to be opened. Their silent and practical logic convinces the reason and the understanding at the same time. Of such sort is always the only pertinent question and the only satisfactory reply.”
—Henry David Thoreau (1817–1862)
