QUESTION 25
Why is TCP desired over UDP for application that require extensive error checking, such as HTTPS?

1. 
   UDP operates without acknowledgments, and TCP sends an acknowledgment for every packet received.
   
2. 
   UDP reliably guarantees delivery of all packets, and TCP drops packets under heavy load
   
3. 
   UDP uses flow control mechanisms for the delivery of packets, and TCP uses congestion control for efficient packet delivery.
   
4. 
   UDP uses sequencing data for packets to arrive in order, and TCP offers the capability to receive packets in random order.
