What are the differences between the storage things? [duplicate]
The usage may differ somewhat between countries or regions, but a wardrobe and closet are both generally separate rooms for storing things. Clothing is generally stored in wardrobes, while anything can be stored in a closet.
A cupboard and cabinet can both be described as a piece of furniture used for storage that has doors and shelves. (Apparently, a cupboard can also be a separate room.)
Where I'm from, cupboards generally denote fixtures hanging from kitchen walls, where they are used to store dishes, glasses, etc. A cabinet is typically bigger and more expensive and is typically placed in a living room, where it is used to store or show off finer possessions, such as family photos, fine china, etc.
A drawer is a box used to store things and which slides into and out of a piece of furniture, such as a desk.
If you visit Google images and type in cabinet and cupboard, most of the pictures actually look very similar in appearance. Also, I should mention that a closet or wardrobe doesn't really have to be a separate room; it can be a piece of furniture that stands upright and usually has a door, almost resembling a small room in some cases.
