Table Of ContentAbout This E-Book
EPUB is an open, industry-standard format for e-books. However, support for
EPUB and its many features varies across reading devices and applications. Use
your device or app settings to customize the presentation to your liking. Settings
that you can customize often include font, font size, single or double column,
landscape or portrait mode, and figures that you can click or tap to enlarge. For
additional information about the settings and features on your reading device or
app, visit the device manufacturer’s Web site.
Many titles include programming code or configuration examples. To
optimize the presentation of these elements, view the e-book in single-column,
landscape mode and adjust the font size to the smallest setting. In addition to
presenting code and configurations in the reflowable text format, we have
included images of the code that mimic the presentation found in the print book;
therefore, where the reflowable format may compromise the presentation of the
code listing, you will see a “Click here to view code image” link. Click the link
to view the print-fidelity code image. To return to the previous page viewed,
