remote web server This is usually performed via FTP or shell commands There are

some good articles on the Joomla! help site regarding this procedure

In true Joomla! fashion, there are even a number of extensions to help with this

process, one worth mentioning is JoomlaPack JoomlaPack is a site backup utility

enabling you to take a copy of your website and database, and reinstall this on any

capable Joomla! server

JoomlaPack not only allows you to move your site from a local development

environment to a remote server, but it also provides you with an easy site backup

feature to use whenever required You can find JoomlaPack by searching for

JoomlaPack at http://extensions.joomla.org

Extension types

The term Extension is a generic term used to describe five main categories of

"extendable elements" for your Joomla! site These are:

Plugins

Plugins are powerful extensions that add additional functionality to your website

Plugins can work on different levels, for example, the content, the search, or

system-wide levels:

An example of a plugin may be to add an easy tag into your Content Article which

will embed a movie easily with no extensive HTML code, or to enhance the Joomla!

search system to also search an included extension

You can manage your plugins from the Extension Manager|Plugin Manager

menu link

Components

A Component can add completely new features to your Joomla! website and they

can often be classed as mini-applications in themselves:

Components add great features such as "shopping carts" and "directory listings"

to your site, and once installed they can be located under the Components menu

Components usually have various elements to them and contain additional

sub-menu links to configuration and management screens

Modules

Modules are extensions that help to deliver information on a page to the end user:

They can display information from simple HTML output to complex information

delivered by the system, and they show this on your site pages Modules are often

associated with components as they provide information to the web page An

example of a module could be a simple weather report, a poll question, or a listing

of events that is generated by an Events component

Modules are managed in the Extensions|Module Manager area.

Templates

A Joomla! Template influences the entire design and structure of your web pages:

by using a Joomla! Template Templates contain module positions which help to

organize and provide structure to your published modules

Templates often contain numerous parameters for adjustments, and these are available

as template options within the Template Manager in the Joomla! Administration

Languages

Languages are a core feature of Joomla! and the packages of these translate the entire

Joomla! interface including the frontend and administration of your Joomla! site:
