From Untitled presentation Jamesville DeWitt Middle School 5th Grade / Modifications for Java Academy Talk -- 2 April 97. by Geoffrey C. Fox
1 The WWW = the World Wide Web is more or less the same as:
  • The Internet
  • The National Information Infrastructure or NII
  • The Digital SuperHighway
2 It is the Digital connection between computers around the world
3 The Internet/WWW consists of Phone Lines or POTS (PLain Old Telephone System). "twisted pair", cable, optical fiber, satellites, cellular phone, wireless
  • These use "protocols" like TCP/IP ATM Ethernet etc
  • Different approachs have different trade-offs: speed, cost, reliability etc.
