00:00:01,000 --> 00:00:05,000
Now that you know all about modules, it's time to learn about components. 

2
00:00:05,001 --> 00:00:08,001
Components are another kind of extension inside of Joomla. 

3
00:00:08,002 --> 00:00:13,002
You might be surprised to know that you've already been working with components. 

4
00:00:13,003 --> 00:00:17,003
Content is a kind of component, and it shows up in the main part of the Web page. 

5
00:00:17,004 --> 00:00:24,004
There is only one component per page, while there may be many modules on the same page. 

6
00:00:24,005 --> 00:00:28,005
So let's take a look at the front-end of our Web site. Taking a look at this, our 

7
00:00:28,006 --> 00:00:35,006
Search module, our main menu module, our Testimonials, and the footer Login down 

8
00:00:35,007 --> 00:00:37,007
here are all modules. 

9
00:00:37,008 --> 00:00:42,008
We've also got a random image module, which is embedded inside of the article 

10
00:00:42,009 --> 00:00:43,009
that here on the homepage. 

11
00:00:43,010 --> 00:00:49,010
So pretty much everything that's wrapped around the article Harnessing wind and 

12
00:00:49,011 --> 00:00:54,011
sun for a cleaner, energized planet is a module, but the content here in the 

13
00:00:54,012 --> 00:00:58,012
middle, the title, and the text; this is a component. 

14
00:00:58,013 --> 00:01:02,013
Another major difference between modules and components is that components 

15
00:01:02,014 --> 00:01:08,014
require configuration, and they are linked to the menu to display on the Web site. 

16
00:01:08,015 --> 00:01:12,015
Rather than being assigned a position on the page, as modules are, 

17
00:01:12,016 --> 00:01:16,016
every component has a different configuration option, and different ways for 

18
00:01:16,017 --> 00:01:17,017
connecting to the menu, 

19
00:01:17,018 --> 00:01:22,018
so watch out for that. I will show you a few components in later videos. 

20
00:01:22,019 --> 00:01:26,019
Finally, a component may also have a module associated with it. 

21
00:01:26,020 --> 00:01:30,020
A great example of this is the Search module where, search is configured in the 

22
00:01:30,021 --> 00:01:33,021
component, but it's displayed in a module. 

23
00:01:33,022 --> 00:01:35,022
Menus work very much the same way. 

24
00:01:35,023 --> 00:01:38,023
Don't let that trip you up. 

25
00:01:38,024 --> 00:01:42,024
In the back-end of Joomla, Components have their own menu here, where you can 

26
00:01:42,025 --> 00:01:47,025
configure the component, and then to display it on the Web site, you're going to 

27
00:01:47,026 --> 00:01:52,026
be going to your Menus, and you'll be making a New menu link, and what will happen 

28
00:01:52,027 --> 00:01:57,027
is when you Select your menu item type, you'll find here in your list of menu 

29
00:01:57,028 --> 00:02:03,028
item types, you'll find something that corresponds to the component of interest. 

30
00:02:03,029 --> 00:02:08,029
So that's a brief summary comparing modules and components, and how they are the 

31
00:02:08,030 --> 00:02:10,030
same, and how they're different. 

32
00:02:10,031 --> 00:02:14,031
So remember that components are the big things on the Web page that fill up the 

33
00:02:14,032 --> 00:02:18,032
main content area. Modules are all of the little supplementary things that 

34
00:02:18,033 --> 00:02:19,033
wrap around it.
