1.2 Terminology   
  Ethernet is a family of frame-based computer networking technologies for local area 
networks (LANs). 
 A local area network (LAN) is a computer network covering a small physical area, 
such as home, office or small group of buildings, such as a school or an airport 
  10BASE-T runs over four wires (two twisted pairs) on a Category 3 or Category 5 
cable. 
  100BASE-TX Uses two pairs, but requires Category 5 cable (FastEthernet) 
  Twisted pair cabling is a form of wiring in which two conductors (the forward and 
return conductors of a single circuit) are twisted together for the purposes of 
cancelling out electromagnetic interference (EMI) from external sources. 
  UTP (unshielded twisted pair) cable is not surrounded by any shielding. 
  STP  (shielded twisted pair) cables are often shielded in attempt to prevent 
electromagnetic interference. 
 The World Wide Web (commonly abbreviated as the "Web") is a system of 
interlinked hypertext documents accessed via the Internet. 
  Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, 
collaborative, hypermedia information systems.
