Describe network protocols : Creating Simple TCP Echo Server

The video tutorial explains the basics of TCP protocol, focusing on its features like connection handling and package reordering. It guides on creating a server socket, managing input and output streams, and how TCP optimizes data transmission. The tutorial demonstrates setting up an application to accept connections and using TELNET clients to connect to a server. It also touches on handling multiple client connections and concludes with a preview of further development in the next video.

What is one of the main advantages of using the TCP protocol in server applications?

• It requires manual byte transmission optimization.

• It does not support multiple client connections.

• It simplifies connection handling and package reordering.

• It requires manual handling of connection reordering.

How does TCP handle the transmission of bytes?

• It waits to collect bytes and sends them in a single segment.

• It requires manual intervention for byte transmission.

• It sends each byte in a separate package.

• It automatically optimizes the transmission process.

Which client is commonly used to connect to a TCP server on Unix systems?

• FTP

• SSH

• TELNET

• Putin

What happens when a second client tries to connect to the same server?

• The connection is accepted and handled by the server.

• The connection is accepted but not handled by the server.

• The server crashes.

• The connection is rejected by the server.

What error message is displayed when the application is stopped?

• Connection timed out.

• Server not found.

• Client disconnected.

• Network connection closed by foreign host.
