A scripting language, script language or extension language, is a programming language that controls a software application. "Scripts" are often treated as distinct from "programs", which execute independently from any other application. At the same time they are distinct from the core code of the application, which is usually written in a different language, and by being accessible to the end user they enable the behavior of the application to be adapted to the user's needs. Scripts are often, but not always, interpreted from the source code or "semi-compiled" to bytecode which is interpreted, unlike the applications they are associated with, which are traditionally compiled to native machine code for the system on which they run. Scripting languages are nearly always embedded in the application with which they are associated.

Social Technologies (social software) is a term used to describe online technologies that have a "social" element  whereby people can easily share content (e.g. web links, photos, videos) with others by allowing them to add labels or tags (i.e. metadata) that include key words, their opinions on relevance and value or other associations.  This emergent metadata creation process often becomes a social activity itself.
Terms and technologies often referred to as social technologies include wikis, blogs, tagging, RSS feeds, web bookmark managers like del.icio.us, social networking sites like LinkedIn, video sites like YouTube, photo sharing sites like Flickr , blog search engines like technorati and others.

SSL (Secure Socket Layer) is an encryption protocol designed to secure communications between web browsers, e-mail and other forms of online data transmission across a network.  It is designed to prevent unauthorized access to data shared across the network. This ensures that the contents of the data flowing between web browsers and servers cannot be read by a third party.
