6. We have introduced physical address and IP address of a computer.
A physical address is also called MAC (Media Access Control) address or Ethernet ID. It is the unique identifier assigned to a network interface for communications.
An IP (Internet Protocol) address is a numerical label assigned to a device participating in a computer network.

(1) What is the physical address of your computer? Please list all you can find.
(2) What is the current IP address, (IPv4 address), of your computer?
Hint:
If you are using Windows, go to "Control Panel > Network and Internet > Network and Sharing Center > ... "
If you are using a Mac, go to "System Preferences > Network > ..."
7. The "ping" command is a computer network tool used to test whether a particular host is reachable across an IP network.
If you are using Windows, bring up a Command Prompt window command-line. Then, enter:
ping www.google.com
If you are using a Mac, start the Terminal (Applications > Utilities > Terminal). Then, enter:
ping www.google.com
