module

A Web Module is the smallest deployable and usable unit of web resources.

Usually modules are lightweight and flexible extensions used for page rendering. These modules are often “boxes” arranged around a component on a typical page.

A Module:

• – encapsulates code and data to implement a particular functionality;

• – has an interface that lets clients to access its functionality in an uniform manner;

• – is easily pluggable with another module that expects its interface;

• – is usually packaged in a single unit so that it can be easily deployed.

Modules are essentially extra bits of content that can be published on some or all of the website pages, depending on whether they’re needed or no – they add to the experience of the site by giving extra functions.
