《操作系统原理》是针对计算机科学技术专业三年级本科生开设的一门专业基础课程。本课程着重学生系统观的培养,通过重点讲述操作系统的内部结构、工作原理及典型技术的实现,使学生建立起对操作系统的整体及各个功能模块的认识,从而系统掌握计算机的专业知识,进一步提升学生的软件开发能力乃至系统软件开发能力。
任何计算机都必须在加载相应的操作系统之后,才能构成一个可以运转的、完整的计算机系统。操作系统的功能是否强大,决定了计算机系统的综合能力;操作系统的性能高低,决定了整个计算机系统的性能;操作系统本身的安全可靠程度,决定了整个计算机系统的安全性和可靠性。操作系统是软件技术的核心和基础运行平台。因此,计算机科学技术专业的学生需要学习和掌握操作系统的基本原理和专业知识。 本课程的教学目标是: 1.掌握操作系统的基本概念、功能组成、系统结构及运行环境; 2.熟悉并运用操作系统工作原理、设计方法和实现技术,理解有代表性、典型的操作系统实例(如UNIX、Linux和Windows); 3.了解操作系统的演化过程、发展研究动向、新技术以及新思想,为后续相关课程的学习打下良好基础,为后续职业发展奠定基石。
主要内容:举例介绍操作系统所做的工作;操作系统的定义与特征;操作系统分类;操作系统发展中的典型技术;典型操作系统的结构。

This is an awesome class. It covers basic knowledge of Operating System. Lectures are valuable and homework is not that easy to complete. Try this class and you won't be regret.

非常实用,在学校老师讲得有的地方不太明白,上Coursera看陈老师的课互补一下立马就懂了。不过个人感觉可以多举例子讲得更深,这样理解会更透彻一些。

课程不过,操作系统的 入门课程,学了还是挺有用的,对操作系统有了基础全面的了解,老师讲课稍微有点照本宣科,对课程的兴趣激发不是很大。

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
