Which elements make up a digital system?

Question

BlackTom AI · Accepted Answer

To begin, consider what is typically meant by a digital system in information technology. A digital system combines its physical components with the software that runs on them. 
Option a: 'Hardware and software' accurately reflects the two fundamental components of any digital system—physical devices (hardware) and the programs or data (software) that operate on them. This pairing is the standard textbook description. 
Option b: 'Software and instructions' is incomplete because it omits the essential hardware that executes software; instructions alone cannot constitute a functioning system without physical devices to run them. 
Option c: 'Hardware and electrical circuits' mentions hardware and a part of its implementation, but it excludes software, which is necessary to define a digital system beyond the static hardware configuration. 
Option d: 'software and binary' mixes a correct element (software) with a representation detail (binary). While software is expressed in binary at a low level, simply citing binary does not capture the complete components of a digital system, since hardware and running software are still required for operation.
