TAILIEUCHUNG - Lecture Operating systems: Internals and design principles (6/E): Chapter 12 - William Stallings

Chapter 12 - File management. After studying this chapter, you should be able to: Describe the basic concepts of files and file systems, understand the principal techniques for file organization and access, define B-trees, explain file directories, understand the requirements for file sharing,. | Chapter 12 File Management Dave Bremer Otago Polytechnic, . ©2008, Prentice Hall Operating Systems: Internals and Design Principles, 6/E William Stallings These slides are intended to help a teacher develop a presentation. This PowerPoint covers the entire chapter and includes too many slides for a single delivery. Professors are encouraged to adapt this presentation in ways which are best suited for their students and environment. 1 Roadmap Overview File organisation and Access File Directories File Sharing Record Blocking Secondary Storage Management File System Security Unix File Management Linux Virtual File System Windows File System We begin with an overview, followed by a look at various file organization schemes. Although file organization is generally beyond the scope of the operating system, it is essential to have a general understanding of the common alternatives to appreciate some of the design tradeoffs involved in file management.
