FAQ
Q: What is WebRTC and how is it used for file sharing?
A: WebRTC is a technology that enables real-time communication and peer-to-peer file sharing directly between web browsers without the need for plugins or third-party software.
Q: What are the key functions 'handle file' and 'select file' used for in WebRTC file sharing?
A: The 'handle file' function is responsible for processing the received file, while the 'select file' function allows users to choose files from their local system to send to others using WebRTC.
Q: Why is chunking files important when dealing with large file sizes in WebRTC file transfer?
A: Chunking files involves breaking large files into smaller segments to prevent memory issues during transfer and to ensure efficient handling of data within WebRTC.
Q: How do web workers contribute to efficient file processing in WebRTC applications?
A: Web workers allow heavy computations to be performed in separate threads, offloading the main browser thread and preventing UI blocking, which enhances the performance of file processing in WebRTC applications.
Q: What role do streams play in handling large files in WebRTC, and why are they important?
A: Streams enable data to be processed in smaller portions without loading the entire file into memory at once, which is crucial for handling large files efficiently in WebRTC to avoid memory issues.
