Modular hardware

Modular hardware breaks down into reusable parts. When one part fails or must be upgraded, it can be quickly replaced with another of the same or similar type, without disrupting everything else.

This makes product take-back simpler and more desirable to the producer.

Relying on it is part of any healthy signal infrastructure, because it reduces the amount of obsolete hardware that will become toxic waste. When such waste is electronic, it is often referred to as e-waste.
