Describe network protocols : Multi-thread Echo Server

The video tutorial explains how to create a server capable of handling multiple clients simultaneously. It discusses various approaches, such as using threads, thread pools, and serving multiple clients from a single thread. The tutorial demonstrates implementing a multi-threaded server using Java, highlighting the use of Lambda expressions and the transferTo method in Java 9 for simplification. The server's functionality is shown through a demonstration of handling multiple TELNET sessions.

What is one method mentioned for handling multiple clients in a server?

• Starting a new thread for each client

• Using a separate server for each client

• Using a single thread for all clients

• Handling clients in a sequential manner

What is a key benefit of using a thread pool?

• It allows for sequential client handling

• It simplifies the server's code

• It increases the server's memory usage

• It reduces the number of threads needed

What is the role of a Lambda expression in the server implementation?

• To handle client connections

• To manage server resources

• To define the echo mechanism

• To start the server

How does the server indicate a successful connection from a client?

• By displaying a pop-up notification

• By logging the connection in a file

• By sending a confirmation email

• By printing a message in the terminal

What happens when a new TELNET session is started?

• The server ignores the new session

• The server logs out the previous session

• The server crashes

• The server echoes input from the new session

What is the purpose of the 'transferTo' method introduced in Java 9?

• To simplify input-output operations

• To manage multiple threads

• To enhance server security

• To increase server speed

What change is necessary in the POM file to use Java 9 features?

• Change the source version to 1.9

• Add a new dependency

• Update the server configuration

• Modify the build script
