Memory Mapping Scheme

What is the memory mapping scheme? Give any one advantage and disadvantage.

MEMORY MAPPING SCHEME:

WEB MAPPING:

Web mapping is the process of designing, implementing, generating and delivering maps on the World Wide Web and its product.

ADVANTAGE & DISADVANTAGE:

While web mapping primarily deals with technological issues, web cartography additionally studies theoretic aspects: the use of web maps, the evaluation and optimization of techniques and workflows, the usability of web maps, social aspects, and more.

Web maps can easily deliver up to date information. If maps are generated automatically from databases, they can display information in almost realtime. They don't need to be printed, mastered and distributed.

Reliability issues – the reliability of the internet and web server infrastructure is not yet good enough. Especially if a web map relies on external, distributed data sources, the original author often cannot guarantee the availability of the information.
