  2. Computer multitasking - Wikipedia

    en.wikipedia.org/wiki/Computer_multitasking

    During batch processing, several different programs were loaded in the computer memory, and the first one began to run. When the first program reached an instruction waiting for a peripheral, the context of this program was stored away, and the second program in memory was given a chance to run.

  3. Batch processing - Wikipedia

    en.wikipedia.org/wiki/Batch_processing

    In order to ensure high-speed processing, batch applications are often integrated with grid computing solutions to partition a batch job over a large number of processors, although there are significant programming challenges in doing so. High volume batch processing places particularly heavy demands on system and application architectures as well.

  4. Time-sharing - Wikipedia

    en.wikipedia.org/wiki/Time-sharing

    These programs might take hours to run. As computers grew in speed, run times dropped, and soon the time taken to start up the next program became a concern. Newer batch processing software and methodologies, including batch operating systems such as IBSYS (1960), decreased these "dead periods" by queuing up programs ready to run. [4]

  5. Time-sharing system evolution - Wikipedia

    en.wikipedia.org/wiki/Time-sharing_system_evolution

    Time-sharing was first proposed in the mid- to late-1950s and first implemented in the early 1960s. The concept was born out of the realization that a single expensive computer could be efficiently utilized by enabling multiprogramming, and, later, by allowing multiple users simultaneous interactive access. [1]

  6. Task (computing) - Wikipedia

    en.wikipedia.org/wiki/Task_(computing)

    In non-interactive execution (batch processing), a task is a unit of execution within a job, [1] [2] with the task itself typically a process. The term "multitasking" primarily refers to the processing sense – multiple tasks executing at the same time – but has nuances of the work sense of multiple tasks being performed at the same time.

  7. Multi-user software - Wikipedia

    en.wikipedia.org/wiki/Multi-user_software

    Multi-user software is computer software that allows access by multiple users of a computer. [1] Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete.

  8. THE multiprogramming system - Wikipedia

    en.wikipedia.org/wiki/THE_multiprogramming_system

    The THE multiprogramming system or THE OS was a computer operating system designed by a team led by Edsger W. Dijkstra, described in monographs in 1965-66 [1] and published in 1968. [2] Dijkstra never named the system; "THE" is simply the abbreviation of "Technische Hogeschool Eindhoven", then the name (in Dutch ) of the Eindhoven University of ...

  9. Compatible Time-Sharing System - Wikipedia

    en.wikipedia.org/wiki/Compatible_Time-Sharing_System

    [8] [9] Debugging programs was an important problem at that time, because with batch processing, it then often took a day from submitting a changed code, to getting the results. John McCarthy wrote a memo about that at MIT, after which a preliminary study committee and a working committee were established at MIT, to develop time sharing.
