Which type of software is designed to run across various platforms, including PCs and mobile devices?

Cross-platform software is designed to operate on multiple operating systems and devices, such as both PCs and mobile devices. This capability means that users can run the same application regardless of their hardware or operating system, providing greater flexibility and accessibility.

For example, many modern applications and web services are developed to be cross-platform, enabling a uniform user experience whether accessed on a desktop computer, a laptop, a tablet, or a smartphone. This ensures that users can work seamlessly across different devices without being constrained by compatibility issues.

Other options do not share this characteristic. Single-platform software is restricted to a specific operating system, consequently limiting its usability across varying devices. Network-based software relies on network connectivity to function and may not inherently support multiple platforms. Local software is typically installed on a single device and only operates on that specific hardware, thus lacking the versatility of cross-platform solutions.
