2.Give one example of devices for Network Layer.
-Router

3.What is the difference between TCP and UDP protocol when a packet goes missing in transit?
- TCP : The packets that sent with TCP is tracked so no data is lost or corrupted in transit
- UDP : The packets are just send to the recipient and it doesn't wait to make sure the recipient received the packet. So if the recipient misses a few packets and it is lost.

3. What is the difference between TCP and UDP protocol when a packet goes missing in transit?
-  TCP/IP is a suite of protocols used by devices to communicate over the Internet and most local networks.
- The User Datagram Protocol (UDP) is used by apps to deliver a faster stream of information by doing away with error-checking.

3. What is the difference between TCP and UDP protocol when a packet goes missing in transit?
- If the packet missing in TCP, it will error-checks by having the recipient send a response back to the sender saying that it has received the message. If the sender doesn’t get a correct response, it can resend the packets to ensure the recipient receives them correctly.
- While in UDP, the sender won’t resend them, it will just continue sending the next packet.

3.What is the difference between TCP and UDP protocol when a packet goes missing in transit?

- TCP guarantees the recipient will receive the packets in order by numbering them. The recipient sends messages back to the sender saying it received the messages. If the sender does not get a correct response, it will resend the packets to ensure the recipient received them.

- When using UDP, packets are just sent to the recipient. The sender will not wait to make sure the recipient received the packet.

3. What is the difference between TCP and UDP protocol when a packet goes missing in transit?
If TCP protocol lost a packet goes missing in transit, it can resend the packets to ensure the recipient receives them. So in TCP, no data will lost or corrupted in transit. But in UDP, it will just continue send the next packets, if the recipient miss or lost packets, they just lost, it won't resend again.

3.What is the difference between TCP and UDP protocol when a packet goes missing in transit?

TCP (Tranmission Control Protocol) is if a packet is lost in transmission, the protocol will notice it has not arrived and request a resend. UDP (User Datagram Protocol ) is if a packet goes missing in transit, it will  not resend the missing packet.

- brouters (it's a combination if router and bridge and it will serve as bridge when forwarding data and it will serve as router when routing system)

3. What is the difference between TCP and UDP protocol when a packet goes missing in transit?

- TCP is a connection-oriented protocol and UDP is connectionless protocol. If the packet missing in TCP, it will resend the packets to unsure it received and with TCP are tracked so no data is loss. While in UDP, it will just continue sending the next packet.
