Models
When a 3D model is imported, Unity represents it as many different objects, including a hierarchy of GameObjects, Meshes (can be skinned depending on import options), AnimationClips, etc. In the Project folder the main imported object is a Model Prefab.
Meshes are attached to a GameObject using a Mesh Filter component. For the mesh to be visible, the GameObject has a Mesh Renderer or other suitable rendering component attached. These components are added automatically by Unity. The mesh will be visible at the GameObject's position with its exact appearance dependent on the Material used by the renderer.
Unity's mesh importer provides many options for controlling the generation of the mesh and associating it with its textures and materials.
