Operating Systems: Journal 2

Throughout the past week, I learned about various essential aspects of operating system design, specifically, regarding process management and scheduling. It was enlightening to discover that a process is an autonomous work unit that operates with its memory space and system resources. This feature allows multiple programs to run simultaneously on a single machine. Moreover, I also familiarized myself with the Process API, which comprises programming interfaces that enable developers to interact with the operating system's processes.

Another crucial concept that I learned about was Limited Direct Execution, a security mechanism that limits specific operations to designated code paths, preventing unauthorized code from executing in privileged contexts. Additionally, scheduling, the process of determining the execution order of processes by the operating system, was another topic I studied. The Multi-level Feedback Queue, a widely used scheduling algorithm, assigns processes to multiple priority levels based on their execution history and resource requirements.

Overall, my understanding of the critical role of processes and scheduling in modern operating systems has significantly increased. These elements play a crucial role in ensuring the efficient and secure operation of computer systems.
