Which system can be adapted by loading only certain software modules?

• A. Lingraphica
• B. PCAD
• C. C-VIC
• D. Dynavox

Answer: (B)

The idea here is modular software design: a system that can be tailored by loading only the necessary software modules, rather than running a fixed, full-suite setup. When a device supports selective loading, you can add or remove language packs, symbol libraries, access methods, and communication modules to fit the user’s specific needs, keeping the interface streamlined and the device efficient. PCAD is designed to adapt in this way, allowing you to load only the software modules that are required for a given user—such as particular language options, symbol sets, or feature sets—without carrying unnecessary components. The other systems typically come as more fixed bundles with predefined features and fewer options to selectively load individual modules, so they don’t align as closely with the ability to customize by loading just what’s needed.
