WordPress is a user-friendly content manage system (CMS) that is used to make feature rich dynamic websites, everything from blogs to business sites.
It comes with a user dashboard that makes it easy for you to add and update your website’s content including pages, posts and media files. It also provides a comment system which you can use to interact with your users.
All this convenience however comes at a price: since it’s dependent on other software it requires upkeep to ensure its secure, up to date and performing optimally.
A static site on the other hand provides no dashboard meaning all content updates have to be coded into the page. They also don’t come with an integrated comment system or other mechanisms for interaction with visitors. On the upside they require little maintenance compared to dynamic sites.
