Exercise How does an email travel down the digital lines?

PowerPoint

1. Find and open Power Point
2. Make as many slides as you wish on the following subject:
3. Subject: “How an email travels down the digital lines”
4. Facts: Every computer that logs on to the Internet gets an internet protocol (i.p)  address
5. An i.p. address has 4 sections with three numbers for example 131.94.114.99
6. 131.94 belongs to FIU
7. 114 belongs to the labs in BA 150
8. 99 belongs to the computer being used
9. When an email leaves the computer with a destination somewhere in Germany, it passes through the modem and has an i.p address. When the email arrives at the other end it can be traced back from Germany to FIU BA 150
10. The email starts in digital format in your computer.
11. It is then converted to analog as it passes through the modem because it has to travel down the analog telephone lines. After it leaves the modem, it arrives at the Central Office (C.O.) of the telephone company.
12. It is then converted back to digital to travel down the digital lines (mainly fiber optics today)
13. The reverse process occurs upon arrival  
14. If you wish to see the ip address of an email that has arrived in your hotmail account here is what to do:
15. Open your hotmail account
16. Open an email for example this one

17. Now go to OPTIONS
18. Go to ADDITIONAL MAIL OPTIONS
19. MAIL DISPLAY SETTINGS
20. Click on ADVANCED for message headers
21. Click OK
22. Back to inbox
23. Open the same email
