This operating system unified 3 its virtual address space with the file system such that each segment in the virtual address space was addressable by a file; that scheme allowed all information it controlled to be addressed directly by the processor and made it possible to control access to all information in the system.
Due to this operating system being written in PL/1, or Programming Language One, it became one of the first operating systems to be written in a high-level language. This operating system unified 3 its virtual address space with the file system such that each segment in the virtual address space was addressable by a file; that scheme allowed all information it controlled to be addressed directly by the processor and made it possible to control access to all information in the system. It was created 6 for the GE-645 mainframe. A Robert Daley and Jack Dennis paper that is a classic in operating system design is titled Virtual Memory, Processes, and Sharing in [this operating system]. It is commonly cited as an example of the second-system effect, compared to it's predecessor, (*) CTSS. This enormously 9 influential time-sharing operating system was created at MIT. For 10 points, name this operating system thatinfluenced the direction of Unix, whose name is a pun on it.
