Put these steps in the proper order to explain communication over the Internet. Instructions

1. Assemble the data packet 2. Correct domain name is idendified (e.g., www.amazon.com). A domain name is a unique name affiliated with an IP address. 3. Look up IP address. Domain name system (DNS) is used to simplify the process. 4. IP (Internet Protocol) Address is added to the packet. 5. Transmission Control Protocol (TCP). TCP is an Internet protocol that ensures delivery of packets. 6. Message is sent/shipped using a variety of different carriers (ISPs). Often messages "hop" or move from one computer to another.

Put the steps for how circuit switching works when placing a land line based phone call in the correct order.

1. Pick up the receiver which creates an open a connection to the local telephone switch. 2. Dial a number, then the switch connects to other switches along the PSTN. 3. When the call is received a circuit is established and will remain open for the entire length of your call. 4. Once you hang up the phone, the circuit is disconnected, and the switches and wire pathways that had been dedicated to your phone call are now free again for other people to use.

There are many protocols that are used to help streamline the communication of all digital devices. For example, Wi-Fi uses the _____ protocol. This protocol ensures that devices enabled with Wi-Fi can connect to any Wi-Fi network.
