Explain the difference between TCP and UDP protocols.

• TCP is a connection-oriented protocol that provides reliable and ordered delivery of data, while UDP is a connectionless protocol that does not guarantee delivery or order of data.

• TCP is a connectionless protocol that does not guarantee delivery or order of data, while UDP is a connection-oriented protocol that provides reliable and ordered delivery of data.

• TCP and UDP are both connectionless protocols that do not guarantee delivery or order of data.

• TCP and UDP are the same protocol with different names.
