Network Programming

In a Python TCP server, what is the primary purpose of the backlog parameter in the listen(backlog) method?

You are using socket.socket(socket.AF_INET, socket.SOCK_DGRAM). You attempt to send 10,000 bytes via sendto(). Why might the operation raise an OSError?

When using socket.setsockopt(), which option is required to immediately reuse a port that is currently in a TIME_WAIT state after a server restart?

You are designing a cross-platform network application. Why is it recommended to use socket.getaddrinfo() instead of socket.gethostbyname()?

You are building an application using SSL/TLS. Which module must be used to wrap a standard socket to provide encrypted communication?

You are configuring a server to handle high-concurrency requests. Why is it preferable to use the select.select() module over a simple blocking recv() loop?

Which method should a developer use to retrieve the IP address and port of the remote peer connected to a TCP socket?

Which socket method is used to bind a socket to a specific address and port?

Which function in the socket module is used to convert a 32-bit integer from host byte order to network byte order?

When handling TCP streams, why might recv(1024) return fewer than 1024 bytes even if the sender sent more?

When implementing a custom application protocol over TCP, how should you handle message framing?

You need to detect if a client has disconnected from your TCP server. What is the standard behavior of recv() when the peer performs a clean shutdown?

What is the effect of setting a socket to non-blocking mode using socket.setblocking(False)?

You are writing a UDP server. What is the main disadvantage of using UDP for high-volume data transmission compared to TCP?

In a multi-threaded Python server, why is it discouraged to share a single socket object across multiple threads without synchronization?

What is the purpose of the socket.recvfrom() method?

Why is the socket.socket() constructor typically called with socket.AF_INET and socket.SOCK_STREAM for a standard web server?

Which of the following is the correct way to close a socket object in Python?

What is the significance of the SO_BROADCAST option in a UDP socket?

When using select.select(inputs, outputs, exceptions), what does the 'outputs' list signify?

Which of the following describes the behavior of TCP_NODELAY?

You are configuring a socket timeout. What happens if you call socket.settimeout(5.0) and the operation exceeds 5 seconds?
