Ajax - preferred by some, hated by others
Ajax is not a genuine Joomla technology, it is just one of programming techniques to made a web page more attractive.
The term botnet refers to a group of computers (sometimes called zombies) that have been infected with malware to perform tasks for whomever distributed said threat. This individual, or organization, controls the botnet by sending instructions to the zombies from one or more Command & Control (C&C) servers. This is one of most used techniques to carry out brute force attacks against servers - or group of servers.
Technically, content is every piece of text and media that is distributed/displayed via your site, whether that be in the component, module, mambot/plugin, or template. In Joomla, when someone says content, they are probably referring to the core content component and the content items that are entered into that component and displayed on your site.
The Frontend is a collective term to name the areas of the website as visitors or registered users see it. A registered user normally works only in the frontend. It is like in a store, where the goods are displayed in shop windows and on shelves. Here you can have a look around.
So, in nutshell: it's everything an unregistered user (Guest) and all other registered users, withouth administrative user rights (the members of main Registered group and it's subgroups) can see.
Sometimes, if more people work on the site, you can get locked out of a certain module or article because the site thinks someone else is still editing that item. When opened, each Joomla item is checked out, this way Joomla protects each editable item from being edited by two separate users at the same itme, and this way avoiding potential confusion and other obvious problems.
ACL stands for access control levels. It refers to who has permission to do what on the website, including read, create, edit, delete, or log in, among other permissions.
Many think of ACL as relating to the front end of a website only. For example, when I log into the website, what articles do I have available to me? And if someone else logs into the site, do they see the same articles, or do they see different ones?
One of frustrating questions for novice Joomlers is the question: What is the difference between a Joomla Component, a Module and a Plugin? This issue can seem rather confusing, but it is really worth understanding this, because this is a key issue in understanding, how Joomla works, and each of them have their specific role and way to set up and operate.
Components, as you already know, are fairly complex and have the ability to display different information in different ways.
Making templates translateable
Joomla is a truly international application and supports the translation of all strings contained within it. Templates are no exception on this. They are a bit neglected, but a little extra time spent here will ensure that the strings used in your templates are translatable will pay back - and will give you an edge over your competitors.
Mambots where the ancestors of current version Joomla plugins. Mambots were introduced in Mambo and offered possibilities to add plug-in logic to your site mainly for the purpose of manipulating content. As the smallest Joomla extensions, they where smaller or bigger chunks of code executed upon being triggered by specially formatted keywords/signal words inserted in the various places of a Joomla 1.0 site.
To find your way around the website, you will need navigation with corresponding links. In Joomla! we call this a menu. You may create as many menus as desired and nest them into as many different ways as you wish. Each menu is a module which can be positioned on a provided area in the template.
Important note: Joomla! is a genuinely menu driven system, the most important behaviors: as what module when to be shown, what template to be used on a certain page, etc all can be controlled using by associating behaviors to menu items. So, plan carefully your menu - it is the core of your site's end user experience!
YOnce the basic setup is done, yo need to tweak your Joomla installation to behave as you need. you will need individual configuration settings for your website elements (components, plugins, modules, content pages, templates): in the Joomla lingo we call them options. These options are applied to the whole website, for users, categories, modules, components. Since Joomla 1.6 this has became standard: you will always find an icon named Options in the backend pages, which are providing you the interface to set your preferences for the given component.
For example in the Joomla 1.6+ in the template manager you have in the Options a way to switch on or off the support for the well known trick to append "?tp=1", which reveals you the available module positions for your templates.
Now you can block attempts to visualize by others these module positions by visiting the address:
BTW: The "tp" stands for template position and the trick is one of core Joomla tricks.
A plugin is a kind of Joomla! extension, in fact the smallest building block of a Joomla site. Plugins provide functions which are associated with trigger events. Joomla provides a set of core plugin events, but any extension can fire (custom) events.
Many people think of a template as their website, but that is an incorrect way of seeing templates. Templates are used for providing a layout and design within which all of the pieces of your Joomla site come together.
The site name/title
There is a setting in the Joomla site configuration, which is often overlooked or used to hold allmost nothing, in best case the URL of the site, the Site Name. You're asked during the install to fill the respective field, and you generally have no clue what to write in that box.
So, what's wrong with that? The site is working, regardless what you wrote there...
You may think one can wrote here anything crosses his mind, right?
Also known as two step-authentication or two-step verification, two-factor authentication is an additional security option for online accounts to help keep them safe.
By default, across all Joomla versions from Joomla 1.0, through Joomla 1.5, Joomla 1.6 to the Joomla 1.7 the basic structure of default user groups is unchanged. The users are generally sorted in 3 main categories, the unregistered/not logged in users, the registered users with frontend only access and the backend users. The exact naming of these main groups are varying across the different Joomla versions, but the default end level groups are the same. The groups and their core permissions are as follows:
