Logic gates are the fundamental building blocks of digital circuits, acting as electronic switches that make decisions based on binary inputs (0 or 1). In Class 12 Physics, these are typically studied in the Semiconductor Electronics chapter.

In Class 12 Chemistry, Chapter 4: The d- and f-Block Elements covers the properties of transition and inner transition metals. The d-block specifically consists of elements in groups 3–12 where the (n-1)d orbitals are progressively filled.

Chapter 5: Magnetism and Matter shifts the focus from how moving charges create magnetism to how materials themselves behave in magnetic fields and the nature of the Earth's magnetism.
