Files provided "random access storage'" [ 4 ] At the same time IBM's product reference manual described such devices as "direct access storage devices [ 6 ] " without any acronym.
The IBM System/360 architecture is the model independent architecture for the entire S/360 line of mainframe computers, including but not limited to the instruction set architecture. The elements of the architecture are documented in the IBM System/360 Principles of Operation [ 1 ] [ 2 ] and the IBM System/360 I/O Interface Channel to Control ...
