WordPress:

The WordPress is a free and open-source content management system (CMS) based on MySQL and PHP. The WordPress is installed on a web server that is either part of an Internet hosting service or a network host in its own right.
WordPress Layout

The new blog looks pretty basic. Before you dive in and start to change the look of things, have a look around at the layout. This will help you later when you start to customize your site, as you’ll know where everything is, and most important, what everything is called.

The layout you are looking at is called a theme. The default WordPress theme features a header at the top with the title placeholder of your site. Along the side are titles and links. This is your sidebar menu. The post is the primary, middle section. The footer is at the bottom of the page.

Let’s look at the post for a moment. Below the post’s title is some information, called the metadata, which contains information about the post such as the date and time the post was made, the author, and the categories the post is in.

Scroll down the page and notice the bar at the end of the page. This is the footer, and for now, it says, “Your blog is proudly powered by WordPress.”

In the sidebar, you can see the different sections with information. You might find a list including Pages, Calendar, Categories, Archives, and Dates. This is the part of the menu or navigation panel that people can use to move around your site, visiting posts from the different categories or time periods.
