My goal in teaching this course is to help youunderstand:<UL><LI> What is an operating system, what does it do, and why do we have it.<LI> The fundamental abstractions provided by operating systems.<LI> The design issues and decisions that go into implementing these abstractions on platforms that work. </UL><H2>Why should someone take this course?</H2> Have you ever considered why your PC crashes about once a day and why workstations don't ? Or how programs access much more memory than there isavailable physically on the machine ? Maybe you know all these and are curious as to what happens "under the covers" with Windows, Unix, NT, andother operating systems. The operating system acts as a resource manager for the computer and if you want to know what kinds of decisions it makes and why, then this course is for you.<H2>Who are we and what do we bring to this course?</H2> I'm a faculty member in the computer science department here. (Checkout my <!WA0><AHREF="http://www.cs.washington.edu/homes/bershad/index.html">homepage</A> for more details about what I do when I'm not teaching.) My area of research is in operating systems and their interaction withcompilers and computer architecture.<P>Your TA is a graduate student with the department. Click <!WA1><ahref="http://www.cs.washington.edu/homes/sungeun/">here</a> to seeyour TA's homepage.<H2>My attitude about teaching and learning</H2> My job is to come prepared to lecture every day, present and clarifymaterial that I feel is important, and guide you all through a seriesof "stories" that are intended to convey the basic points of thecourse. People tell me that I'm pretty good at conveying concepts andwalking through complicated material with examples and analogies.People also tell me that I'm terrible "on-my-feet" when I have to add,subtract, multiply, or divide, or when I need to remember where thesemicolon goes. I use slides so that I can work out those details inadvance. Nevertheless, I will make mistakes in lecture and on thehandouts. I'm grateful to anyone who can point these mistakes out.I'll correct them as quickly as I can. <P><H3>Your Job</H3>Teaching is my responsibility. Learning is yours. There are mechanicalthings that I do in order to teach effectively (example, using slides,exams, homeworks, soliciting feedback), and there are mechanicalthings that you should do to learn effectively. I can pretty muchguarantee that if you operate using a few simple guidelines you willget a high grade in this course: <UL><LI> Come to lecture PREPARED. At the very least, this means havingread through the lecture notes from the previous lecture. At best, itmeans having read the next relevant section in the text, begun workingon the homeworks, and have questions ready to ask.<LI> Come to all lectures. The lectures are the course. You can'tslide by just by skimming the notes. Over the course of the quarter,we're all likely to miss one or two lectures -- myself included. WhenI miss a lecture, it is my responsibility to make sure that thingsproceed as much as possible as if I were there. The same has to betrue of you; if you miss a lecture, it is your responsibility todetermine what happened and how it relates to the rest of the course.Good resources are these web pages, and the person sitting next toyou.<LI> Do the homeworks. I'm like you. I hate homeworks. They are asmuch a pain to put together, grade, and adminster as they are to do.If I thought we could, I'd have no homeworks at all. But, they're likeworking out or running -- you do it, as painful as it is, and youimprove. The more you do, the faster you do them, etc... The homeworksalso help me to understand what you are understanding, and moreimportantly, what you are not.<LI> Tell us how things are going. Both the good and the bad. We'vecreated an <!WA2><A HREF="http://www.cs.washington.edu/education/courses/451/CurrentQuarter/feedback.html">anonymous feedback page</A>that you can use to tell us what you like and what you don't like.Check it out for more details. Or you can just send us regular mail.Or just come by my office.<LI> Try to have fun. For many of you the first programming classthat you take where you have to pull together a lot of differentconcepts to make progress. The results can be pretty impressive. </UL>That's about it. Basically, we've each got a job to do this quarterwith one another. Let's try to make it as productive and effective aspossible. <P> Click <!WA3><A HREF="http://www.cs.washington.edu/education/courses/451/CurrentQuarter/syllabus.html">here</A> to go on to the actual course syllabus.</html>⌨️ 快捷键说明
