The WordPress admin area is the controlling center of a WordPress powered website. An administrator has full access to all the sections within the WordPress Admin dashboard area. Users with other roles such as editor, contributor, or author have limited access to the admin dashboard area. Some users such as users with the subscriber role only have access to their profile page inside the admin dashboard area.
At the top of each dashboard screen is the toolbar or admin bar. Its provides access to several administrative functions. On the left side is the main navigation that provides access to most of the WordPress managements tools. Each major section typically comes with a sub-menu that can fly out and expand to show more options.
The dashboard area in the middle of the screen is called the work area. This is where you can write, edit, and delete posts as well as adjust settings. At the bottom of each administration dashboard page is the footer. The footer contains links to WordPress sites and the version of WordPress that you currently have installed.
