Here's a breakdown:

* Peninsular Plateau: This is a large plateau in India that covers most of the southern and central parts of the country. It is a vast, triangular-shaped landform.

* Deccan Plateau: This is a specific region within the Peninsular Plateau. It is located in the southern part of the Peninsular Plateau, roughly corresponding to the states of Maharashtra, Karnataka, and Telangana.

Think of it this way:

* Peninsular Plateau is like the entire continent of Africa.

* Deccan Plateau is like the country of South Africa, located within Africa.

So, while the Deccan Plateau is part of the Peninsular Plateau, they are not the same.
