Operating Systems

A good overview regarding operating systems. It was particularly important to me because I am aiming to become a DevOps engineer.

course content

• History of computing generations
• OS structures (Monolithic, Layered, Microkernel, Client-Server)
• Process vs. Thread management
• The Process Control Block (PCB) and 5-state model
• Memory hierarchy (Cache vs. RAM vs. Secondary storage)
• Virtual memory and paging
• File system operations and disk partitioning
• Disk defragmentation and backup strategies

afterthoughts

This course certainly filled some knowledge gaps for me. I would have really enjoyed for it to have a more pragmatic approach to operating systems. To my liking, it should have explored init systems (e.g. systemd) in real life scenarios. My expectations were to high for this course.
