Obviously all sites can do this to some degree, but typically a portal will have a wide range of resources, usually including a search facility, directory of other sites, news, e-mail etc. Portals can be general (eg Yahoo) or be specific to a particular industry, occupation or field of interest.
A portal script is a piece of software that lets you run a "portal like" site without any real programming or development knowledge.
But in the most accurate context a portal is a site that acts as a gateway to online features and or services.
