Blender's main Area is a predefined workspace. Users can make their own workspaces, but by default you will be loaded into the standard Layout workspace. This workspace consists of the following Editors...

3D Viewport: This is where you view and interact with your 3D scene.

Outliner: Displays a hierarchical list of all objects in your scene. It helps you select and organize objects.

Properties: Contains detailed settings for selected objects, including modifiers, materials, and scene properties.

Timeline: Primarly used for animation. The timeline shows frames and keyframes to help control animated sequences.
