What is WEP and is it supported?
Wired Equivalent Privacy (WEP) is a basic wireless security provided by Wi-Fi. In some
instances, WEP may be all a home- or small-business user needs to protect wireless data.
WEP is supported in 64-bit and 128-bit encryption modes. As 128-bit encryption provides a
longer algorithm that takes longer to decode, it can provide better security than basic 64-bit
encryption. Windows Mobile 5.0 supports WEP.
What is WPA and is it supported?
Short for Wi-Fi Protected Access, a Wi-Fi standard that is designed to improve upon the
security features of WEP. The technology is designed to work with existing Wi-Fi products
that are enabled with WEP (i.e., as a software upgrade to existing hardware), but the
technology includes two improvements over WEP:
Improved data encryption through the temporal key integrity protocol (TKIP). TKIP
scrambles the keys using a hashing algorithm and, by adding an integrity-checking
feature, ensures that the keys have not been tampered with.
User authentication through the extensible authentication protocol (EAP). WEP regulates
access to a wireless network based on a computer's hardware-specific MAC address,
which is relatively simple to be sniffed out and stolen. EAP is built on a more secure
public-key encryption system to ensure that only authorized network users can access the
network.
What is a VPN?
Virtual Private Network (VPN) is a type of technology designed to increase the security of
information transferred over the Internet. VPN works with either wired or wireless networks,
as well as with dial-up connections. VPN creates a private encrypted tunnel from the end
user's computer, through the local wireless network, through the Internet, to the corporate
servers and database.
What type of display technology does the iPAQ hx2000 series Pocket feature?
The iPAQ hx2000 series Pocket PC utilizes a 3.5" transflective TFT QVGA 64K color LED
backlight display and allows better and easier viewing of documents, images, and web
pages in both portrait and landscape modes
What is the difference between reflective and transflective display?
