[edit section] Input and Output Devices in Windows XP
The 70-270 exam will test you on your ability to identify and correctly implement different input and output devices in Windows XP. In this guide, we will explore some of the various I/O devices available in Windows XP and how to install, configure, and manage them.
[edit section] What are I/O Devices?
Input devices aid in the input of information or instructions into a computer. Typical input devices include the ubiquitous keyboard and mouse, tablets, digitizers, cameras, and scanners. These devices allow for users to import, or input, data from outside the PC to the PC.
In contrast, output devices aid in the output of information from a computer. Typical output devices include printers, copiers, monitors, and speakers. These devices allow for the computer to return human-understandable output from the digital PC.
[edit section] Keyboards and Mice in Windows XP
Keyboards are managed through the Keyboard applet in the Control Panel. Windows allows you to modify character repeat rate and cursors speed, among other settings. Additionally, you can configure keyboard drivers using the Keyboard applet.
Mice in Windows XP are configured through the Mouse applet in the Control Panel. This applet allows you to configure double-click speed as well as button configuration, pointer icon options, and so forth. The applet also allows you to configure additional mice and monitor the device drivers of your current mouse.
[edit section] Scanners and Cameras in Windows XP
Scanners and cameras in Windows XP are managed and configured through the Scanners and cameras folder. In XP, each scanner or camera gets its own device icon and properties in a setup similar to the way that printers are managed. Imaging devices (scanners and cameras) can be added through the Add an Imaging Device wizard, which will prompt you for relevant configuration information and drivers.
[edit section] Smartcards in Windows XP
Smart cards are devices that allow a user to verify his or her identity by inserting the card into a reader. Windows XP allows for the integration of smart cards into the operating system through third-party software. Know that upon removal of the card, Windows can continue operation, lock the PC, or log off.
[edit section] Networking in Windows XP
Networking requires the configuration of a network interface card or NIC. Network cards are configured via the Device Manager or through the network card button on a particular network connection display.
We will discuss networking in much greater detail later on, but we are concerned with hardware in this guide.
[edit section] Infrared Communication in Windows XP
Infrared Data Association, or IrDA, allows for short-range communication between two connected hosts via infrared waves. Infrared network connections can be created using the Advanced options of the Network wizard. Choose to set up an infrared connection and configure one computer as the “Host” while the other is a “Guest.” IrDA speeds can range from 115.2 KBP/s to 16 MBP/s.
[edit section] Shifting Gears
We have covered some of the basic ideas of input and output in Windows XP. The exam does not heavily feature these items, but you should be aware of their existence and the various tools used to configure them. Because this has been a shorter lesson, we will have a comprehensive review of the items covered in the first seven lessons of our guide.

b. It will remain compressed and retain its compression attribute
c. It will be decompressed and lose its compression attribute
d. It will remain compressed but lose its compression attribute
e. None of the above
7. If a user has full control of a folder via NTFS permissions and Read access via Sharing permissions, what is his effective level of access when trying to access the folder remotely?
a. Read
b. Write
c. Read and Execute
d. Modify
e. Full Control
8. Which of the following is not an input device?
a. Pointing device
b. Keyboard
c. Human interface device
d. Digitizer
e. Monitor
[edit section] Answers
1. Riprep is used to prepare remote installations of Windows XP. The answer is C.
2. Deny permissions override allow permissions, so John’s effective permissions are the sum of the allow permissions (Read + Modify = Modify) minus the deny permission (Write). Since he can still execute, his effective permission is Read + Execute. The answer is D.
3. Running winnt32.exe with the /dudisable switch will prevent Windows from attempting to configure dynamic updates. The answer is B.
4. NETSETUP.LOG is the record of all workgroup and domain joining issues and is also the answer. The answer is D.
5. The Block setting will prevent unsigned drivers from being installed. The answer is C.
6. When a compressed file is moved on the same volume, the file is not actually being moved – the reference to the file (its location) is simply modified as an attribute. Therefore, the file remains in place, complete with its compression attribute. Note that when a compression attribute is lost, the file is decompressed. So, the answer is B.
7. Sharing permissions on an NTFS volume combine the most restrictive of both permissions. The combination of Full Control and Read access is just Read access via sharing. The answer is A.
8. A monitor outputs the video signal from a computer. The answer is E.
