What is software defined as in a computer system?

In a computer system, software is defined as the list of instructions that tell the hardware how to perform specific tasks. This includes operating systems, applications, and various programs that enable the user to interact with the hardware and execute commands. Software essentially acts as the intermediary between the user and the computer's physical components, translating user inputs into actions that the hardware can perform.

The other options refer to aspects that are not classified as software. The physical components themselves relate to hardware, the amount of storage deals with memory capacity and hardware specifications, and the graphical interface is a part of the software but does not encompass the entirety of software itself. Therefore, recognizing software as the set of instructions for task performance captures its essential role in a computer system.
