Portal : A portal provides a single point of entry to widely distributed information on the web, and it offers a unified way to access that diverse information. Portals provide an easy way to configure desired content on a personal web page. Plus, portals provide a consistent look and feel. Users can take advantage of diverse applications in the same manner, making it easy for them to access information from various sources.

A portal is a web-based application that commonly provides personalization, authentication,
[and] content aggregation from different sources and hosts the presentation
layer of information systems.
