Introduction to Socket Programming

What is a socket in networking?

• A socket is an endpoint for communication in a network, defined by an IP address and a port number.

• A socket is a software application that manages network traffic.

• A socket is a type of network cable used for data transmission.

• A socket is a physical device used to connect computers.

Which protocol is commonly used with sockets?

• SSH and Telnet

• TCP and UDP

• SMTP and IMAP

• HTTP and FTP

What are the two main types of sockets?

• Packet sockets and streamlining sockets

• Protocol sockets and interface sockets

• Connection sockets and transmission sockets

• Stream sockets and datagram sockets

What does the term 'bind' refer to in socket programming?

• The term 'bind' refers to creating a new socket instance.

• The term 'bind' refers to sending data over a network.

• The term 'bind' refers to closing a socket connection.

• The term 'bind' refers to associating a socket with a local address and port.

What is the purpose of the listen() function?

• To close a server after it has finished processing requests.

• To send data to a client over a network connection.

• To prepare a server to accept incoming connections.

• To log incoming connection attempts for security purposes.

What does the accept() function do?

• The accept() function closes an existing connection.

• The accept() function accepts incoming connections on a socket.

• The accept() function sends data over a socket.

• The accept() function creates a new socket for communication.

Which function is used to send data over a socket?

• sendData()

• pushData()

• send() or sendall()

• transmit()

What is the difference between TCP and UDP sockets?

• TCP is connection-oriented and reliable; UDP is connectionless and faster but less reliable.

• TCP and UDP are both connectionless protocols.

• UDP guarantees delivery of packets and is connection-oriented.

• TCP is faster than UDP and used for streaming.

What is a socket descriptor?

• A socket descriptor is a type of network protocol.

• A socket descriptor is a command used to initiate a network connection.

• A socket descriptor is a file used for data storage.

• A socket descriptor is an integer that identifies an open socket for network communication.

What is the role of the connect() function in socket programming?

• The connect() function listens for incoming connections.

• The connect() function closes an existing connection.

• The connect() function establishes a connection to a server in socket programming.

• The connect() function sends data to a server.
