Python and Networking

What is the difference between TCP and UDP?

• TCP and UDP are both unreliable protocols

• TCP and UDP are the same

• TCP is a connectionless protocol and UDP is a connection-oriented protocol

• TCP is a connection-oriented protocol that provides reliable and ordered delivery of data, while UDP is a connectionless protocol that provides faster but less reliable delivery of data.

Explain the concept of socket programming in Python.

• Socket programming in Python is not supported by any operating system

• Socket programming in Python is only used for local communication within the same device

• Socket programming in Python allows for network communication between processes running on different devices.

• Socket programming in Python is used for creating GUI applications

What is the purpose of the 'requests' module in Python?

• To calculate mathematical equations

• To create graphics

• To play music

• To make HTTP requests

How does a firewall work in a network?

• It sends spam emails to all the network users

• It monitors and controls network traffic based on security rules.

• It randomly shuts down the network without any reason

• It plays music to entertain the network users

Explain the difference between IPv4 and IPv6.

• IPv4 is used for wireless networks while IPv6 is used for wired networks.

• IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.

• IPv4 uses 64-bit addresses while IPv6 uses 256-bit addresses.

• IPv4 is more secure than IPv6.

What is the role of a router in a network?

• Forwards data packets between computer networks

• Manages the power supply for computer networks

• Stores data packets in a network

• Sends emails between computer networks

How can you handle exceptions in Python socket programming?

• By using try-except blocks to catch and handle specific errors that may occur during socket operations.

• By using if-else statements to handle exceptions

• By terminating the program when an exception occurs

• By ignoring the exceptions and continuing with the program

What is the purpose of the 'socket' module in Python?

• It is used for mathematical calculations.

• It is used for data encryption.

• It is used for network communication.

• It is used for creating GUI applications.

Explain the concept of port forwarding in networking.

• Port forwarding encrypts communication requests

• Port forwarding blocks communication requests

• Port forwarding duplicates communication requests

• Port forwarding redirects communication requests from one address and port number to another
