Описание книги “Современные операционные системы”:
The third edition of this book differs from the second edition in numerous
ways. To start with, the chapters have been reordered to place the central material
at the beginning. There is also now more of a focus on the operating system as the
creator of abstractions. Chapter 1, which has been heavily updated, introduces all
the concepts. Chapter 2 is about the abstraction of the CPU into multiple
processes. Chapter 3 is about the abstraction of physical memory into address
spaces (virtual memory). Chapter 4 is about the abstraction of the disk into files.
Together, processes, virtual address spaces, and files are the key concepts that operating systems provide, so these chapters are now placed earlier than they previously had been.
Chapter 1 has been heavily modified and updated in many places. For example,
an introduction to the C programming language and the C run-time model is
given for readers familiar only with Java.
In Chapter 2, the discussion of threads has been revised and expanded reflecting
their new importance. Among other things, there is now a section on IEEE
standard Pthreads.
Chapter 3, on memory management, has been reorganized to emphasize the
idea that one of the key functions of an operating system is to provide the abstraction of virtual address space for each process. Older material on memory
management in batch systems has been removed, and the material on the implementation of paging has been updated to focus on the need to make it handle the larger address spaces now common and also the need for speed.
Chapters 4-7 have been updated, with older material removed and some new
material added. The sections on current research in these chapters have been
rewritten from scratch. Many new problems and programming exercises have
been added.
Chapter 8 has been updated, including some material on multicore systems.
A whole new section on virtualization technology, hypervisors, and virtual
machines have been added with VMware used as an example.
Chapter 9 has been heavily revised and reorganized, with considerable new
material on exploiting code bugs, malware, and defenses against them.
Chapter 10, on Linux, is a revision of the old Chapter 10 (on UNIX and
Linux). The focus is clearly on Linux now, with a great deal of new material.
Chapter 11, on Windows Vista, is a major revision of the old Chap. 11 (on
Windows 2000). It brings the treatment of Windows completely up to date.
Chapter 12 is new. I felt that embedded operating systems, such as those
found on cell phones and PDAs, are neglected in most textbooks, despite the fact
that there are more of them out there than there are PCs and notebooks. This edition
remedies this problem, with an extended discussion of Symbian OS, which is
widely used on Smart Phones.
Chapter 13, on operating system design, is largely unchanged from the second
edition.
