Use of the word "cache" in the computer context originated in 1967 during preparation of an article for publication in the IBM Systems Journal. The paper concerned an exciting memory improvement in Model 85, a latecomer in the IBM System/360 product line. The Journal editor, Lyle R. Johnson, pleaded for a more descriptive term than "high-speed buffer". When none was forthcoming, he suggested the noun "cache", meaning a safekeeping or storage place . The paper was published in early 1968, the authors were honoured by आय.बी.एम., their work was widely welcomed and subsequently improved upon, and "cache" soon became standard usage in computer literature.
