•Nature of Computer technology and 
       Internet technology has changed a 
       lot in the past 10 years and will 
       change a lot in the next 10 years
     •Most of you in 1991 had not even 
       heard of Internet, World-Wide Web, 
       Networks, Personal Digital Assistant 
       (PDA), Windows NT, Linux
     •These are all now part of Computer 
       Technology and Internet technology 
                           
     •What will we be talking about in 
       2011?
     •What new Computer and Internet 
       Technology is being developed that 
       will be commonplace in a few years?
     •Some things seem promising, but 
       may become equivalent of Betamax 
       and 8-track tapes
     •Look at some areas of Computer and 
       Internet Technology development
                           
     Networking Technology
      Networking Technology
           Power-Line Networking
           Power-Line Networking
   Way to connect 
   computers in 
   home or office 
   using electrical 
   wiring
                           
           Power-Line Networking
           Power-Line Networking
      •More convenient than phone lines
      •Connect computer to network through the 
        outlet that provides power
      •Data travels through electrical wiring
      •Requires no new wiring and adds no cost 
        to electric bill
      •Power-line networking is inexpensive 
        method for connecting computers in 
        different places in home or office
                                 
             Wireless Networking
             Wireless Networking
     •Creates network by sending infrared or radio 
       signals between computers
     •Better than Power-line networking; some 
       computers are not “plugged in” to electrical 
       outlet
     •Laptop with wireless network card is 
       completely portable throughout home or 
       office
     •IrDA (Infrared Direct Access) is standard for 
       devices to communicate using infrared light 
       pulses
