Cloud Network
A group of remote servers that store and share data over the internet.
Data Packet
A small piece of data that travels across a network from one device to another.
Hub

Speed
How fast data is sent or received by a device.
Switch
A device that sends data only to the correct device on a network.
TCP/IP Model
A 4-layer model that shows how data is moved through a network.
