Document Summary
Transistors and batch systems: operator carries input tape to 7094 machine. E. operator carries output tape to 1401. Typical input structure: 1401 prints output, card specifying runtime, account, and programmer. card tells o/s to load fortran compiler from. D. card directs the operating system to the object system tape: program is compiled program just compiled. E. card tells o/s to run the program: card marked the end of a job, 3. Ics provided a major price/performance advantage over 2nd generation machines. Multiple jobs could be held in main memory at once so that the. Cpu could be kept busy nearly 100% of the time. Spooling read job from cards onto the disk. Once a job finished the o/s could load a new job into the now empty memory partition. Timesharing when multiple users are logged into the same system, cpu allocated to jobs requiring service, not idle ones: 4.
