Question
Open Activity Monitor's Network tab to view network activity. The easiest way to open Activity Monitor is to select the Applications folder from the dock, select the Utilities folder, then select Activity Monitor. Once the Activity Monitor window is open, select the Network button. Arrange your desktop into two windows: one with Activity Monitor and one with a browser. Now navigate to several Web sites and note what happens in Activity Monitor. The graph uses red for sent packets and blue for received packets. Data transport speeds are listed as "Data received/sec" and "Data sent/sec." What are typical speeds for sending and receiving data on your network? Monitor network activity. Continue watching the graph when you are not using the browser. Why do you think there is activity even when you are not actively using network services? Look at the process chart above the graph. The Sent Bytes and Rcvd Bytes columns of the chart lists active processes and shows when they send or receive data. Can you determine which applications are sending and receiving data over the network even when you are not actively using network services? Open the Network Utility and start Netstat. You can find the Network Utility by selecting the Applications folder. If the Network Utility is not there, look in the Utilities folder. When the Network Utility window opens, select the Netstat tab and then select the option: Display the state of all current socket connections. Click the Netstat button to view the report. Look at the beginning of the report. The Local Address is the origin of outgoing packets. The Foreign Address is the source of incoming packets. List three of the foreign addresses. Use WHOIS to see if you can associate them with activities that you have recently carried out.Explanation / Answer
