  5. Activity 3.1 Infrastructure issues • Make a list of the potential problems for users of e-business services developed by The B2C Company. • You should consider problems faced by users of e-business applications who are both internal and external to the organization. • Base your answer on problems you have experienced on a web site that can be related to network, hardware and software failures or problems with data quality.

Typical problems • Web site communications too slow. • Web site not available. • Bugs on site through pages being unavailable or information typed in forms not being executed. • Ordered products not delivered on time. • E-mails not replied to. • Customers’ privacy or trust is broken through security problems such as credit cards being stolen or addresses sold to other companies.

Advantages: – Reduced product lifecycles – Reduced costs through higher productivity and savings on hard copy – Better customer service – Distribution of information through remote offices nationally and globally

  18. World Wide Web • WWW is the most common technique for publishing information on the Internet. It is accessed through web browsers which display web pages of embedded graphics and HTML/XMLencoded text. • Web browsers provide an easy method of accessing and viewing information stored as web documents on different servers. • Web servers store and present the web pages accessed by web browsers
