How does UDP differ from TCP?

  1. UDP is connectionless with no error checking

  2. UDP uses a connection-oriented approach

  3. UDP is used exclusively for email

  4. UDP cannot be used for real-time applications

The correct answer is: UDP is connectionless with no error checking

UDP is different from TCP because it does not establish a connection before transmitting data and it also does not have error checking, meaning that no guarantee is made for the delivery of data. Option B is incorrect because TCP is the protocol that uses a connection-oriented approach. Option C is incorrect because UDP is not exclusively used for email, it can be used for a variety of applications. Option D is incorrect because UDP can be used for real-time applications, but may not be the best choice due to its lack of error checking.
