Course Syllabus

Examine how operating systems and design have evolved as changes in hardware and software led to contemporary operating systems. Topics include basic OS concepts, methods of OS design and construction, process coordination, management, and algorithms for CPU scheduling, memory, and general resource allocation.

This course includes the following units:

• Unit 1: Introduction to Operating Systems
• Unit 2: Processes and Threads
• Unit 3: Synchronization
• Unit 4: CPU Scheduling
• Unit 5: Deadlock
• Unit 6: Memory Management
• Unit 7: File System
• Unit 8: Security
• Unit 9: Networking

Upon successful completion of this course, you will be able to:

• Understand the functions, structures, and evolution of operating systems;
• Evaluate design choices and trade-offs in the implementation of different operating systems, and decide which type of operating system would be most appropriate for a given situation;
• Evaluate, debug, and modify operating system code to achieve the desired functionality; and
• Explain data structures, algorithms, computer architecture, and programming in the context of operating systems.

Throughout this course, you will also see learning outcomes in each unit. You can use those learning outcomes to help organize your studies and gauge your progress.

This course's primary learning materials are articles, lectures, and videos.

All course materials are free to access and can be found in each unit of the course. Pay close attention to the notes that accompany these course materials, as they will tell you what to focus on in each resource and will help you understand how the learning materials fit into the course as a whole. You can also see a list of all the learning materials in this course at this link.

Some parts of this course may have been created or reviewed with the support of artificial intelligence (AI). To make sure you receive accurate, high-quality, and academically sound learning materials, all AI-assisted content is carefully checked and approved by Saylor Academy's faculty and subject matter experts.

Only the final exam is considered when awarding you a grade for this course. To pass this course, you will need to earn a grade of 70% or higher on the final exam.

Your score on the exam will be calculated as soon as you complete it. Be sure to study in between each attempt! If you do not pass the exam, you will not complete this course or receive a certificate of completion. You can attempt the exam as many times as you want.

There are end-of-unit assessments in this course that are designed to help you study and do not factor into your final course grade. You can take them as many times as you want until you understand the concepts they cover.

You can see all of these assessments at this link.

The certificate earned by passing this self-paced course displays the program hours you completed and continuing education credits (CEUs). CEUs document successful completion of courses that are designed to improve the knowledge and skills of working adults. Many industries value CEUs, and now your certificate reflects them clearly, and they may be used to support career advancement or to meet professional licensing standards. This course contains 12.0 CEUs.

CS401: Operating Systems is a self-paced course, meaning you can decide when to start and complete the course. We estimate the "average" student will take 120 hours to complete. We recommend studying at a comfortable pace and scheduling your study time in advance.

Learning new material can be challenging, so here are a few study strategies to help you succeed:

• Take notes on terms, practices, and theories. This helps you understand each concept in context and provides a refresher for later study.
• Test yourself on what you remember and how well you understand the concepts. Reflecting on what you've learned improves long-term memory retention.

This course is delivered entirely online. You will need access to a computer or web-capable mobile device and consistent internet access to view or download resources and complete auto-graded assessments and the final exam.

To access the full course, including assessments and the final exam, log into your Saylor Academy account and enroll in the course. If you don't have an account, you can create one for free here. Note that tracking progress and taking assessments require you to log in.
