Explanation

Software is a collection of programs and instructions that directs the computer's hardware to perform specific tasks.
It enhances the hardware's capabilities by making it functional for a wide variety of purposes, from simple calculations to complex medical applications.
Without software, the physical components (hardware) of a computer would be unable to perform any useful function for the end-user.
The core function of software is to make the hardware usable and versatile.

Option B: The speed of the Central Processing Unit (CPU) is a physical attribute determined by its hardware architecture and clock rate. Software cannot change the physical speed limit of the CPU.
Option C: This option is incorrect because one of the statements ('Increase the speed of central processing unit') is false.
Option D: This option is incorrect because the first statement ('Enhances the capabilities of the hardware machine') is a true and accurate description of software's function.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Function of computer software as background academic context rather than a clinical decision trigger.
In nursing informatics, understanding the distinction between hardware and software is crucial. Electronic Health Record (EHR) systems are application software that run on hospital computers (hardware) to manage patient data.
Specialized software controls medical devices like infusion pumps and ventilators. The software dictates the rate and volume of medication or air delivered, while the hardware performs the physical action.
What if? A hospital invests in the latest, fastest computers (hardware), but the EHR (software) is poorly designed and slow. Nurses will experience frustrating delays in charting and accessing patient information, which can negatively impact workflow and patient safety, despite the powerful hardware.

How to Approach the Question

First, understand the fundamental definitions of the key terms: 'hardware' and 'software'. Hardware is the physical machine, and software is the set of instructions that runs on it.
Evaluate the first option: 'Enhances the capabilities of the hardware machine'. Ask yourself if software makes the hardware more useful and versatile. Yes, it tells the hardware what to do. This is a correct statement.
Evaluate the second option: 'Increase the speed of central processing unit'. Consider if a program can change the physical properties of a computer chip. No, CPU speed is a fixed hardware specification. This statement is incorrect.
Since the second option is false, the 'Both of the above' option must also be false.
Since the first option is true, the 'None of the above' option must be false.
Conclude that the only correct statement is the first one.
