What is the purpose of a software emulator program?

A software emulator is designed to replicate the functions of one computer system on another, allowing software from one platform to run on different hardware or operating systems. This emulation enables users to execute applications or games that were originally designed for a distinct environment, providing flexibility and expanded functionality without requiring the original hardware.

The correct answer highlights this capability, illustrating how emulators permit the use of multiple computers and platforms without the need for additional purchases. This is particularly valuable for users who want to maintain access to legacy software or games that are no longer available on modern systems.

The other options focus on enhancing graphics or improving connectivity, which do not align with the primary function of emulators. Furthermore, while emulators might indirectly help run outdated applications, they do not specifically serve the purpose of replacing them, making the correct answer the optimal choice in this context.
