Which technology is similar to RDP but fully cross-platform and open-source?

• A. Load Balancer
• B. Remote Desktop Protocol (RDP)
• C. Virtual Network Computing (VNC)
• D. Unified Communications

Answer: (C)

Think of technology that lets you view and control another computer's desktop across different operating systems while staying open and community-driven. Virtual Network Computing uses the RFB protocol to send the host’s framebuffer to a client, and it has many open-source implementations. This makes it truly cross-platform—Windows, macOS, Linux, and more—and freely available to use and modify. In contrast, RDP is a Microsoft-originated protocol with support on other systems but not fully open-source, so it isn’t as platform-agnostic or openly developed. The other options aren’t remote desktop technologies: a load balancer routes network traffic, and unified communications focuses on messaging and collaboration, not desktop sharing. So the best fit is Virtual Network Computing.
