11. Hubs and Switches – These simple, affordable but effective small boxes provide a central connection point for the networking of multiple computers. http://www.pccitizen.com/hubsandswitches.htm

12. Modem - Modem, short for modulator-demodulator is an electronic device that converts a computer’s digital signals into specific frequencies to travel over telephone or cable television lines.

13. Ray Tomlinson - Ray Tomlinson was the first computer engineer to invent an Internet-based e-mail in late 1971.He had initially been experimenting with SNDMSG, a program that the ARPANET programmers used on networked computers to leave messages for one another. Building off of this program, Tomlinson used a file transfer protocol called CYPNET to adapt the SNDMSG program so that e-mails could be sent to any computer on the ARPANET network. Ray Tomlinson chose the @ symbol to indicate which user was at which computer.
