From the WordPress point of view, our News is a post category. We can create as many post categories as we like. When we create a post (perhaps some news, or an announcement, etc) we simply decide which post category (or categories) we assign it to.
The Post Category screen is reached via Posts > Categories
After creating a new category it is likely you will want to add a link to the category page to the site navigation system. If so go to Appearance > Menus and locate / tick the category (in the Categories panel) / drag-drop to the required location and Save as per general instruction for adding page to navigation system here
