Introduction to Operating Systems

  • Description
  • Outcome
  • Certification
  • In this free online course Introduction to Operating Systems you will learn about operating systems and the role they play in a computer system.

    The course begins by introducing you to Operating Systems (OS) and their function. You will learn about where an OS occurs in the layers of a computer system. You will learn about different operating system types, about hardware addresses and the three types of addresses you can use. You will be introduced to the concept of hardware abstraction and the advantages of abstraction. You will also learn about an OS as a resource manager and what it involves.

    Next, you will be introduced to processes and system calls, and how they access the kernel for user processes. You will learn about an Operating System Structure, the modules of the structure and about two different types of OS structures. You will learn about the Central Processing Unit (CPU) and how it is considered the most critical resource in the computer system. You will learn how the CPU is shared between different applications. You will learn about multiprogramming and multitasking and how these methods work differently to sharing a single CPU.

    This free Alison course will be of great interest to any computer science and engineering students or any learner who wishes to learn more about operating systems.

    Perquisites: The learner will need a understanding of C programming and a good understanding of computer organisation and architecture.

  • Having completed this course you will be able to:
    - Describe what an Operating System is and its role in a computer system.
    - Explain why hardware has addresses and the types of addresses.
    - Describe how processes work.
    - List the different CPU types a computer can have.
    - Describe why isolation is need for running applications.

  • All Alison courses are free to study. To successfully complete a course you must score 80% or higher in each course assessments. Upon successful completion of a course, you can choose to make your achievement formal by purchasing an official Alison Diploma, Certificate or PDF.

    Having an official Alison document is a great way to share your success. Plus it’s:

    • Ideal for including in CVs, job applications and portfolios
    • An indication of your ability to learn and achieve high results
    • An incentive to continue to empower yourself through learning
    • A tangible way of supporting the Alison mission to empower people everywhere through education.
