    Study Notes

    Evolution of Operating Systems

    • Serial Processing: Early computing method where tasks are processed sequentially without overlap.
    • Batch Processing: Groups tasks together to minimize idle CPU time, allowing execution without user intervention.
    • Multiprogramming: Enables multiple programs to reside in memory and share CPU resources, improving system efficiency.

    Types of Operating Systems

    • Batch Operating System: Processes batches of jobs without user interaction, optimizing resource use and reducing overall processing time.
    • Multiprogramming Operating System: Supports multiple programs running simultaneously, allowing better utilization of CPU time.
    • Network Operating System: Manages network resources, allowing communication between computers and efficient data sharing.
    • Distributed Operating System: Coordinates a group of independent computers working together to present as a single system.

    Communication and Networking

    • Data Communication: The transfer of data between devices through physical paths like wires or optical fibers.
    • Data Encoding: Involves transforming data into coded formats to facilitate efficient transmission and storage.
    • Private vs Public Communication: Differentiates between non-shared communication networks versus those available to the general public.

    Integrated Circuit Technology

    • Integrated Circuits (ICs): Combine multiple electronic components on a single silicon chip for enhanced performance and reduced size.
    • Packaging: Chips are housed with protective encasing and connection pins, often in dual in-line (DIP) or multi-pin configurations for integration with other systems.

    External/Auxiliary Memory

    • Importance of Secondary Storage: Due to high cost and volatility of RAM, external storage like magnetic disks and tapes are crucial for permanent data retention.
    • Magnetic Disks: Circular plastic platters coated with magnetized material, used for data storage through magnetic read/write heads.
    • Data Organization: Disk data stored in tracks and sectors, facilitating structured data retrieval.

    Printing Technologies

    • Impact Printers: Utilize mechanical impact against inked ribbons, producing text. Examples include dot matrix printers known for their cost-effectiveness but lower print quality.
    • Ink Jet Printers: Spray tiny droplets of ink without mechanical impact, allowing higher quality prints and quieter operation.
    • Printing Speed: Speeds vary significantly between printer types; dot matrix typically ranges from 40 to 1,000 characters per second, while inkjet can exceed 300 characters per second.

    Course Overview

    • Course Structure: Comprised of four modules focusing on computer systems, operating systems, application packages, and data communication.
    • Course Aims: To provide a foundational understanding of computer technology, operations, and relevant software tools.
    • Assignments and Assessments: Students must engage with course materials, complete self-assessments, and submit Tutor Marked Assignments for evaluation.
