Raspberry Pi 3 &4 64bit ARM Kernel Update

All newer Raspberry Pi models, like the 3/3+ series, the 4 and also the 400 all have a 64-bit CPU, but the Raspberry Pi OS still works with 32-bit by default for compatibility reasons.

What is the benefit of 64-bit?

To take full advantage of the capabilities of a 64-bit CPU, you should also run a 64-bit operating system on it. This can speed up some calculations considerably.

A 64-bit operating system can also run 32-bit programs without any problems, so you usually don't have any disadvantages due to software that doesn't run anymore or similar.

Bounded Context defines the scope of a domain model, i.e., it encompasses the business logic for a particular domain.

The inner core is assumed to remain consistent as long as the business use case does not change.

All outer layers are always assumed to change over time, i.e., they are only binding for the current point in time, e.g., when the technology used has reached its final stage of maturity and/or is overtaken by new innovations.

The interfaces/connectors define the interaction between the relevant (data, technology, business, etc.) layers of the domain model.
