WAP Architecture - Wireless Application Environment

The uppermost layer in the WAP stack, the wireless application environment (WAE), is a general-purpose application environment based on a combination of WWW and mobile telephony technologies. The primary objective of the WAE is to establish an interoperable environment that allows operators and service providers to build applications and services that can reach a wide variety of different wireless platforms in an effi cient and useful manner. Various components of the WAE are:? Addressing model: WAP uses the same addressing model as the one used on the Internet (i.e., URL). A URL uniquely identifi es a resource on a server that can be retrieved using well-known protocols. WAP also uses Uniform Resource Identifiers (URI). A URI is used for addressing resources that are not necessarily accessed...

Defining Good Internet Security

There have always been debates as to how much Computer Security is actually needed these days. The debate rages on not just with professionals but those who use their computers mostly from the home as well. While there will probably never be a distinct answer as to how much is actually needed the answer is always going to be different depending on how a computer and network are used as well as what type of data they store and even the type of applications used within those machines. Those using home desktops and laptops will generally require far less Internet Security than those running a business. An individual browsing the internet and checking his/her email don't need as comprehensive security because they don't attract much attention to themselves. Sure they are faced with threats...

A Computer Security Geek Goes to Las Vegas

Las Vegas:An IS Perspective on New Slot MachinesA recent trip to Las Vegas prompted an "aha moment". After I got over the initial shock of how much things have changed since the days when I used to frequently travel to Vegas (I was one of those thousands who used to regularly attend the COMDEX show), I ventured back onto the gaming floor. Aside from having a lot more poker tables than I remember from 8 years ago, the thing that struck me was that the slot machines changed. Where once the gaming floors were full of the "jing, jing, jing" of coins hitting the metal trays of the slot machines, there are now magnetic card readers, bar code scanners and separate machines that convert bills into "credits" and back again. Money gets converted to digital bits, printed on bar-coded cards that players...

Introduction to Wireless Application Protocol

WAP has become the de facto global industry standard for providing data to wireless hand-held mobile devices [4 � 10] . WAP takes a client/server approach and incorporatesa relatively simple microbrowser into the mobile phone, requiring only limited resourceson mobile phones. WAP puts the intelligence in the WAP Gateways while adding justa microbrowser to the mobile phones themselves. Microbrowser-based services andapplications reside temporarily on servers, not permanently in phones. The WAP is aimedat turning mass-market phones into a network-based smart phone. The philosophy behindWAP�s approach is to use as few resources as possible on the hand-held device and compensate for the constraints of the device by enriching the functionality of the network.WAP specifi es a thin-client microbrowser...
