OSI/TCP Model Quiz

Which layer of the OSI model is responsible for routing and forwarding data packets?

• Layer 5

• Layer 7

• Layer 3

• Layer 9

What is the main difference between TCP and UDP?

• TCP is connectionless and does not guarantee delivery or order of packets, while UDP is connection-oriented and ensures reliable data delivery.

• TCP and UDP have the same level of reliability in data delivery.

• TCP and UDP are both connection-oriented protocols.

• TCP is connection-oriented and ensures reliable data delivery, while UDP is connectionless and does not guarantee delivery or order of packets.

Which protocol is used for email communication?
