Overview of OS/2
... OS/2 can be categorized in two categories: system I/O and user I/O. Processes use system I/O to perform file level; I/O to secondary storage devices managed by the file systems. System I/o is programmed using the file system API. Processes utilize user I/O to interact with the user by employing keyb ...
