Health IT Specialist
In many countries, governments have recently enacted
laws that require health-care providers to computerize
certain parts of their practices. For example, patient
health records, medical billing, supply and drug invento-
ries, and medical equipment maintenance records will
soon need to be in electronic form if they are not already.
This requirement opens up many job opportunities for
health IT specialists. A health IT specialist plans and sets
up health-care recordkeeping systems that meet all gov-
ernment requirements and keeps such systems up to date
and in good repair. This job requires at least an associ-
ate's degree in a computer-related field, with a bachelor's
or master's degree preferred for supervisory positions.

A Tour of.Windows 7
The Windows 7 interface, called the
desktop
, is your starting point for
most of the activities you perform in Windows 7. From the desktop, you
can run programs, manage files, access the Internet, check the status of
devices, and more.
desktop
The Windows 7 interface, on which
windows open containing applications. Can also
refer specifically to the background image.
Your Windows desktop is like a physical workspace in some ways. You
can have multiple files and projects open at the same time, spread out
on the desktop so you can see each one of them. The desktop can be
changed to suit your personal style. The desktop background can be a
solid color, as in Figure 5.1, or it can be a picture of your choice.
The
taskbar
is the thin bar across the bottom of the screen. It is used to
start programs and manage the programs that are already running. At
the far-left end is the
Start button
. The small graphics you see on the
desktop are called
icons
. An icon can sit on the desktop, as the Recycle
Bin icon does in Figure 5.1, or it can be
pinned
to the taskbar for easy
access. For example, in Figure 5.1, four pinned icons appear to the right
of the Start button. The center of the taskbar is blank in Figure 5.1,
but if any programs were running or windows open, buttons for those
programs or windows would appear there. Some other icons are at the
right end of the taskbar, but these aren't pinned there. That area is called
the
notification area
(or
system tray
), and the icons there represent
information from programs or system components that are running in
the background, such as the Volume Control and the Battery Meter. At
the far-right end of the taskbar is a clock.
