Q3.

Discuss the problems encountered using text across computer platforms and in different languages.

·        In the current model of electronic publishing, texts can be delivered with a cross-application approach using the Standard Generalized Markup Language (SGML). This same level of cross-platform and cross-application delivery has not been achieved for all of the characters that these texts include. An ideal solution to the problems in character representation would be cross-platform, flexible, and durable. Many in the computing, publishing, and library worlds have suggested that the Unicode standard is the wave of the future.

Q4.

Your boss wants you to create a hypermedia system for web visitors to find technical support information about your company. What are some of the implications in creating this system? Should you hand-build the links or use an automatic indexing system? Why?

·         Hypermedia is used as a logical extension of the term hypertext in which graphics, audio, video, plain text and hyperlinks intertwine to create a generally non-linear medium of information. This can be used to give the web visitors a more interactive experience. Hypermedia includes use of sound, video, image and text.

This will attract the user and helps the user to know about the product of the company more easily and this will definitely improve both communication between the user and company. The user can view and test the product so for as view of the product is concerned. However, the hypermedia restricts the speed of the web and it also enhances the time taken for opening the site.

·         So for as the use of hand build indexing system and automatic indexing is concerned, it is the glue that holds the content together. It is the layer of order which makes the data base product, robust, and responsive, thus best ever to serve the needs of the organization. However without automatic indexing, one may find the precise bit of data that will ignite a new market.

·         Advance Indexing System is an automatic link generation enhances reusability of the multimedia material after it is organized in a lesson structure. This approach allows authors to create different context-based presentations starting from the expected skill of the target users. Advanced indexing schemes will be further available for dynamic and interactive hypermedia generation.
