**课程名称：** 操作系统基础 (Fundamentals of Operating Systems) **课程概述：** 本课程旨在揭秘操作系统 (OS) 的核心概念，帮助软件工程师深入理解操作系统的内部工作原理。操作系统负责协调众多进程，管理内存、磁盘和网络访问，并通过 CPU 调度执行进程。尽管听起来简单，但这项任务极其复杂。一个工程师对操作系统的理解程度，直接影响其编写高效程序的潜力。 作者以自身经历为例，强调了理解“黑箱”内部机制的重要性。如同数据库查询性能下降是由于缺乏对内部机制的理解一样，软件工程师在使用内存、磁盘和网络时，如果不了解操作系统是如何实现的，就容易写出效率低下的代码。 这门课程将通过 Demystify（揭秘）的方式，讲解操作系统中最基础但也最关键的部分。作者鼓励有编程经验的学生学习本课程，因为编程经验能帮助学生更好地理解和关联课程内容。课程中将涉及 Linux、Windows 和 Mac 等多种操作系统。 **核心内容（根据概述推断）：** * **进程管理：** 进程的创建、销毁、调度机制。 * **内存管理：** 内存分配、虚拟内存、内存保护等。 * **I/O 管理：** 磁盘和网络访问的管理。 * **系统调用：** 应用程序与操作系统之间的接口。 **建议：** 具备一定的编程经验。
Operating systems orchestrate many processes, allow access to memory, disk and network and execute the process by scheduling them to the CPU. Sounds simple when we put it this way but this task is vast. So vast indeed that writing programs that are efficient really depends on how much understanding the engineer has in operating systems. I have been fascinated by revealing and demystifying anything that is hidden from me, mainly because by treating black boxes as black boxes that takes input and produces output, I feel that I am at the mercy of this black box. Databases were a black box for me a decade ago, I was at completely lost when a query that I wrote was originally running fast but after few month it had gone slow. The reason is I didn't really have any understanding of database systems and how their internals work.The same thing is true for operation systems, we run our program which turns into a process that uses bit of memory and access disk and network but we really don't know how this is done and as a result we as engineers are bound to write inefficient code.I built this course to demystify what I believe are the fundamentals operating systems to software engineers. Like all my courses, I recommend the student having some programming experience to take this course, it just makes the course relatable. I will be using multiple operating systems like Linux, Windows and Mac in this course. I hope you enjoy it.
