The video tutorial demonstrates the interoperability of GRPC across different programming languages, specifically Golang and Java. It shows how the same protocol buffer files enable communication between services implemented in different languages. The demo includes running a Go server with both Go and Java clients, and vice versa, proving the seamless interaction. The tutorial concludes by emphasizing GRPC's flexibility and its ability to work with any language that uses the same protocol buffer files.

What is the key component that allows GRPC to be used across different programming languages?

• The network configuration

• The protocol buffer files

• The programming language itself

• The operating system

In the demonstration, which two programming languages were used to show GRPC interoperability?

• Ruby and PHP

• JavaScript and TypeScript

• Java and Golang

• Python and C++

What types of RPC calls were demonstrated in the video?

• Client streaming, batch processing, unary, server streaming

• Unary, batch processing, client streaming, bidirectional streaming

• Unary, server streaming, client streaming, bidirectional streaming

• Server streaming, batch processing, unary, bidirectional streaming

What was the outcome when a Java client communicated with a Golang server?

• The client received no response

• The communication was successful

• The server crashed

• The communication failed

What is the main takeaway regarding GRPC's use across different languages?

• It is limited to Java and Golang

• It requires different protocol files for each language

• It is only effective in a single language environment

• It can be used with any language that shares the same protocol buffer file
