Describe network protocols : Java API to Network Programming

The video tutorial covers the java.net package, emphasizing its importance in Java 9. It explains key classes like Socket, ServerSocket, DatagramSocket, and InetAddress, detailing their roles in networking. The Socket class is used for TCP client connections, while ServerSocket handles server-side connections. DatagramSocket is for UDP packets, and InetAddress manages Internet addresses. The tutorial also hints at future topics like Java NIO channels.

What is the primary purpose of the socket class in the java.net package?

• To create a new TCP client connection to a remote server

• To manage multiple network interfaces

• To send and receive UDP packets

• To listen for incoming connections on a server port

Which class is used to create a socket that listens for incoming connections on a server port?

• Socket

• ServerSocket

• InetAddress

• DatagramSocket

What is a key characteristic of the UDP protocol that affects how datagram sockets are used?

• It is not connection-oriented

• It requires a separate server and client socket

• It only supports TCP connections

• It is connection-oriented

Which class should be used for managing internet addresses when creating sockets?

• Socket

• DatagramPacket

• InetAddress

• ServerSocket

What is the role of a datagram packet in Java networking?

• To establish a TCP connection

• To contain the data that travels over the network

• To listen for incoming connections

• To manage multiple IP addresses
