In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software , computer hardware , peripheral devices , humans , and combinations of these. [ 1 ]
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
Example of a single system computer bus. A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce ...
(This latter, special interface, is known as the computer human interface, AKA human computer interface, or HCI; formerly called the man-machine interface.) [3] Integrated circuit (IC) designers are driving current technologies into innovative approaches for new products. Hence, multiple layers of active devices are being proposed as single ...
The Simple Bus Architecture [1] (SBA) is a form of computer architecture. It is made up software tools and intellectual property cores ( IP core ) interconnected by buses using simple and clear rules, that allow the implementation of an embedded system ( SoC ).
Diagram of the Intel Core 2 microarchitecture. In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor.

So, depending on the point of view, hardware registers are like memory with additional hardware-related functions; or, memory circuits are like hardware registers that just store data. [citation needed] Hardware registers are used in the interface between software and peripherals. Software writes them to send information to the device, and ...
