Relearning Computer Networks, Operating Systems, and Database Management Systems for Industrial Work

To successfully relearn and apply computer networks, operating systems, and database management systems (DBMS) in an industrial context, there are several courses and resources you should consider. These foundational subjects are crucial for understanding and contributing effectively to modern digital infrastructure. Below, I will outline the key areas you should focus on, including the specific courses that can help you enhance your skills.

1. Deep Dive into Computer Networks and Operating Systems

If you genuinely want to dig into computer networks and operating systems (OS) like top-tier institutions such as MIT, the following courses are highly recommended:

MIT 6.828 - Operating Systems Engineering (Fall 2012)

This course is designed to develop nearly every component of an operating system. It is one of the most challenging courses I have experienced, but it provides an in-depth understanding of the internals of a modern OS. You can find its overview and detailed curriculum on the official MIT OpenCourseWare. It covers everything from device drivers to file systems to process management, making it an invaluable resource for anyone serious about their OS knowledge.

Stanford University CS144: Systems Analysis and Design

This course, offered by Stanford University, aims to develop a deep understanding of how network protocols and operating systems interact. By the end of the course, you will have the capability to implement a router. You can find more details about this course and enroll for an online version through Stanford Online.

2. Introduction to Databases

While I haven't completed this specific course, my friend who did suggests that it is highly valuable. Database management systems (DBMS) are central to data storage and retrieval, and a solid understanding of databases can improve your ability to manage and analyze data effectively. Common courses that cover this subject include MIT 6.820 Introduction to Database Systems and Coursera's Database Design and Modelling.

3. Practical Application in Mobile Environments

Depending on your specific interests and career goals, you may want to delve into the intricacies of Android development or Linux-based systems. If you are interested in enhancing your application on Android devices, a good starting point is understanding the underlying Linux foundation. This knowledge can help you debug and optimize your apps, especially in mobile environments where resources are limited.

General Advice

Throughout your learning journey, it is important to stay updated with the latest research and technologies in your chosen fields. Engage with the broader community through forums, conferences, and online platforms like Stack Overflow, GitHub, and Reddit’s r/programming. Additionally, consider practical projects or internships to apply your theoretical knowledge in real-world scenarios.
