Networking Assignment
5. Many online tools are available to test the speed of your network connection. Use Google to search for "speed test"; you will find a lot of them. For example,
Go to https://www.speedtest.net/. Click on "Begin Test"
How fast is your connection? Provide your download and upload speed here.
Does your download speed match your upload speed? Provide one reason why it is better to have your download speed greater than your upload speed.
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.
In this question, you need to find out:
What is the physical address of your computer? List all you can find.
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. Enter:
ping www.google.com
If you are using a Mac, start the Terminal (Applications > Utilities > Terminal). Enter:
ping www.google.com
What is the IP address of www.google.com?
How long did it take (round-trip time)?
Now, try to ping a website in Japan: ping www.hitachi.co.jp
What is the IP address of www.hitachi.com?
How long did it take (round-trip time)?
Did it take more time or less time to send a packet to the Hitachi URL or the Google URL? Why?
