single.dvi 17 Free-Space Management In this chapter, we take a small detour from our discussion of virtual- izing memory to discuss a fundamental aspect of any memory manage- ment system, whether it be a malloc library (managing pages of a pro- cess’s heap) or the OS itself (managing portions of the address space of a […]
single.dvi 26 Concurrency: An Introduction Thus far, we have seen the development of the basic abstractions that the OS performs. We have seen how to take a single physical CPU and turn it into multiple virtual CPUs, thus enabling the illusion of multiple pro- grams running at the same time. We have also seen how
single.dvi 37 Hard Disk Drives The last chapter introduced the general concept of an I/O device and showed you how the OS might interact with such a beast. In this chapter, we dive into more detail about one device in particular: the hard disk drive. These drives have been the main form of persistent data

single.dvi 5 Interlude: Process API ASIDE: INTERLUDES Interludes will cover more practical aspects of systems, including a par- ticular focus on operating system APIs and how to use them. If you don’t like practical things, you could skip these interludes. But you should like practical things, because, well, they are generally useful in real life;

single.dvi 55 Access Control Chapter by Peter Reiher (UCLA) 55.1 Introduction So we know what our security goals are, we have at least a general sense of the security policies we’d like to enforce, and we have some ev- idence about who is requesting various system services that might (or might not) violate our policies.
single.dvi 56 Protecting Information With Cryptography Chapter by Peter Reiher (UCLA) 56.1 Introduction In previous chapters, we’ve discussed clarifying your security goals, determining your security policies, using authentication mechanisms to identify principals, and using access control mechanisms to enforce poli- cies concerning which principals can access which computer resources in which ways. While we identified
single.dvi 21 Beyond Physical Memory: Mechanisms Thus far, we’ve assumed that an address space is unrealistically small and fits into physical memory. In fact, we’ve been assuming that every address space of every running process fits into memory. We will now relax these big assumptions, and assume that we wish to support many concurrently-running large

single.dvi F Laboratory: Tutorial This is a very brief document to familiarize you with the basics of the C programming environment on UNIX systems. It is not comprehensive or particularly detailed, but should just give you enough to get you going. A couple of general points of advice about programming: if you want to become

Please be sure to check that out if interested. This chapter presents some ideas for systems projects. We usually do about six or seven projects in a 15-week semester, meaning one every

Student: Hold on. Are you one of the professors who wrote this book? I thought we were both just fake constructs, used to summarize some main points,
