The networking, hardware, and software technologies that you learned about in the previous modules are key to any eBusiness solution.
For decades they have been important elements of business computing infrastructures. The same cannot be said for Web technologies, which also lie at the core of eBusiness solutions.
Web technologies are part and parcel of today's eBusiness, because the human user interface in eBusiness is usually Web-based.
In this module, you will learn in-depth information about the Web technologies available for eBusiness solutions and you will acquire the following skills:
- Describe the function of Web browsers
- Identify the key browser-related issues to consider when designing an eBusiness solution
- Describe the function of Web servers
- Describe the importance of security in eBusiness
- Identify the key considerations when choosing one security provider over another
- Describe the function of search engines
A wireless application service provider, also known as WASP, is essentially the same as a conventional application service provider except it focuses on mobile wireless technology for service
access and as a delivery mechanism. A WASP performs similar services for mobile wireless customers as the ASP does for its customers on wired lines. The wireless application service provider
offers services catering to users of cellular phones, personal digital assistants, and handheld devices, and, generally, to any mobile wireless client.
The service provider is more constrained in what it can offer because of the limits of the access device and great varieties in available device technology.
In the business-to-consumer market, wireless application service offerings include, for example, e-mail access, unified messaging, event registration, shopping, and online banking.
In the business-to-business market, wireless application services include account management and billing, backend banking, and remote sensing; in the future, this could include
- user location identification,
- system monitoring, and
- wireless network diagnosing.
Future extensions of this model could be wireless network access providers, WASPs that offer wireless network infrastructure to customers on a pay-by-use basis in and around coffee shops,
restaurants, airports, and train stations. Often, ASPs already offer wireless interaction possibilities and thus embrace both models. Because of the similarity
of the WASP and ASP models, I do not discuss the WASP model further. All concepts introduced apply equally well to this kind of application service provider.
The next lesson is about the function of web browsers.
