{"product_id":"9780321680037","title":"The Design and Implementation of the FreeBSD Operating System","description":"\u003cp\u003eAs in earlier Addison-Wesley books on the UNIX-based BSD operating system, Kirk McKusick and George Neville-Neil deliver here the most comprehensive, up-to-date, and authoritative technical information on the internal structure of open source FreeBSD. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; system administrators can learn how to maintain, tune, and configure the system; and systems programmers can learn how to extend, enhance, and interface to the system. \u003c\/p\u003e \u003cp\u003eThe authors provide a concise overview of FreeBSD's design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the systems facilities. As a result, readers can use this book as both a practical reference and an in-depth study of a contemporary, portable, open source operating system. \u003c\/p\u003e \u003cp\u003eThis book:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDetails the many performance improvements in the virtual memory system\u003c\/li\u003e \u003cli\u003eDescribes the new symmetric multiprocessor support\u003c\/li\u003e \u003cli\u003eIncludes new sections on threads and their scheduling\u003c\/li\u003e \u003cli\u003eIntroduces the new jail facility to ease the hosting of multiple domains\u003c\/li\u003e \u003cli\u003eUpdates information on networking and interprocess communication \u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eAlready widely used for Internet services and firewalls, high-availability servers, and general timesharing systems, the lean quality of FreeBSD also suits the growing area of embedded systems.
