Which interface consists of things like program counter registers interrupts and terminals?

The interface that consists of elements like the program counter, registers, interrupts, and terminals is typically part of a computer's hardware architecture, specifically within its central processing unit (CPU) and input/output (I/O) systems. The program counter and registers are crucial for instruction execution and data storage, while interrupts manage the CPU's attention to various tasks. Terminals serve as user interfaces for communication with the system. Together, these components facilitate the operation and control of a computer system.
