 2. ProcessesWe are now about to embark on a detailed study of how operating systems, in general, and MINIX 3, in particular, are designed and constructed. The most central concept in any operating system is the process: an abstraction of a running program. Everything else hinges on this concept, and it is important that the operating system designer (and student) understand this concept well. 3. Input/Output This chapter is organized as follows. First we will look at some of the principles of how I/O hardware is organized. Then we will look at I/O software in general. I/O software can be structured in layers, with each layer having a well-defined task to perform. We will look at these layers to see what they do and how they fit together. 4. Memory Managemente Memory is an important resource that must be carefully managed. While the average home computer nowadays has two thousand times as much memory as the IBM 7094, programs and the data they are expected to handle have also grown tremendously. To paraphrase Parkinson's law, "Programs and their data expand to fill the memory available to hold them." In this chapter we will study how operating systems manage memory. 5. File Systems All computer applications need to store and retrieve information. While a process is running, it can store a limited amount of information within its own address space. However, the storage capacity is restricted to the size of the virtual address space. For some applications this size is adequate, but for others, such as airline reservations, banking, or corporate record keeping, it is far too small. 6. Reading List and Bibliography This chapter is intended as an aid to readers interested in pursuing their study of operating systems further. Section 6.1 is a list of suggested readings. Section 6.2 is an alphabetical bibliography of all books and articles cited in this book. Download free ebook for linux: Operating Systems Design and Implementation Third Edition
