Short for Wireless Transport Layer Security. WTLS is the security layer of the WAP, providing privacy, data integrity and authentication for WAP services. WTLS, designed specifically for the wireless environment, is needed because the client and the server must be authenticated in order for wireless transactions to remain secure and because the connection needs to be encrypted. For example, a user making a transaction with a bank over a wireless device needs to know that the connection is secure and private and not subject to a security breach during transfer (sometimes referred to as a man-in-the-middle attack). WTLS is needed because mobile networks do not provide complete end-to-end security.
WTLS is based on the widely used TLS v1.0 security layer used in Internet. Because of the nature of wireless transmissions, modifications were made to the TLS v1.0 in order to accommodate for wireless’ low bandwidth, datagram connection, limited processing power and memory capacity, and cryptography exporting restrictions.
- Wireless Wide Area Network (WWAN)
Short for Wireless WAN (wide-area network), a wireless computer networkthat spans a relatively large geographical area.
The WWW prefix (short for World Wide Web) that precedes URL addresses is an indication that the Web address exists on the vast network of the World Wide Web. Sometimes in a URL the “WWW” is followed by a number, such as “WWW1” or “WWW2.” The number that follows the “WWW” indicates that the data […]
Wide XGA (WXGA) is a display class (or standard) that supports a resolution of 1366 to 1280 pixels horizontally and 768 to 720 pixels vertically. WXGA is a standard commonly associated with LCD computer monitors and televisions used for widescreen display and projection.
Pronounced WIZ-zee-wig. Short for what you see is what you get. A WYSIWYG application is one that enables you to see on the display screen exactly what will appear when the document is printed. This differs, for example, from word processors that are incapable of displaying different fonts and graphics on the display screen even […]
Short for what you see is what you print, and pronounced wizzy-whip, refers to the ability of a computer system to print colors exactly as they appear on a monitor. WYSIWYP printing requires a special program, called a color management system (CMS) to calibrate the monitor and printer.
