Learning About Your Computers Hardware Devices
Computers can have all sorts of hardware devices installed in and connected to
them. Keeping track of all these components and their related device drivers without
a little help would be nearly impossible, and that’s where Device Manager comes in
handy. You’ll use Device Manager to learn about your computer’s hardware compo-
nents and the device drivers they use.
Viewing Installed Hardware
Device Manager is your window to the hardware components installed on your com-
puter. You can access Device Manager and view all the hardware devices installed on
your computer by completing the following steps:
1. Click Start and then click Control Panel.
2. In the Control Panel, click System and Maintenance.
3. Scroll down and then click Device Manager.
As Figure 5-6 shows, Device Manager’s default view shows the devices installed in or
connected to your computer by device type. If you expand a device type node, such
as DVD/CD-ROM devices, you’ll see the actual hardware components that are
installed. The device list shows warning symbols if there are problems with a device:

Chapter 5: Customizing Your Computer’s Hardware Devices
A yellow warning symbol with an exclamation point indicates a problem with a
device.
A red X indicates a device that the user or administrator improperly installed or
disabled for some reason.
The options on the View menu allow you to change the way devices are listed. The
View menu options include:
Devices by type
Displays devices by the type of device installed, such as disk drives or display
adapters. This is the default view.
Devices by connection
Displays devices by the type of connection. For example, you may see the base
node for the computer as ACPI Multiprocessor PC or ACPI x86-based PC. If you
expand this, you’ll see the ACPI connections and a connection for the com-
puter’s hardware bus, such as PCI Bus. If you then expand the PCI Bus connec-
tion, you’ll see all the hardware connected to the PCI bus.
Resources by type
Displays the status of allocated resources by resource type and type of device
using a resource. Resource types are direct memory access (DMA) channels,
input/output (I/O) ports, interrupt requests (IRQ), and memory addresses.
