About This eBook
ePUB is an open, industry-standard format for
eBooks. However, support of 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, click the Back button on your
device or app.
