There is a "cloud" symbol labeled "communication channel." Obviously the cloud symbol is an abstraction. Think about a computer and a server on home or school network and tell, in about a paragraph, what kinds of components that cloud represents. Now think about the connection between your home or school computer and a huge data center such as those operated by Google. Can we still use the cloud symbol to represent a communication channel? Why or why not? If the cloud symbol can still be used, what changes about the abstraction from the first example, home network, to the second, connection to the data center?
