Q .

What is WEP and is it supported?

 

 

 

 

A .

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.

 

 

 

 

Q .

What is WPA and is it supported?

 

 

 

 

A .

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.

 

 

 

 

Q .

What is a VPN?

 

 

 

 

A .

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.

 

 

 

Display

Q .

What type of display technology does the iPAQ hx2000 series Pocket feature?

 

 

 

 

A .

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

 

 

 

 

Q .

What is the difference between reflective and transflective display?
