NT1210 Chapter Four Mind Map

1. Sending Bits with electricity and copper wires

   • AC/DC circuits
     • DC current flows oneway
     • AC current alternating flow
       • Frequency, amplitude, period. and phase
       • encoding scheme
   • Electrical circuits using network cabling
     • NIC, port, interface, sockets
     • Transmitter < Bits flow right to left >Reciever
   • Sending Data over electrical circuits
     • Bit rate
     • Encoding Bits over one circuits
       • encoding scheme
     • Sending Bits over multiple circuits
       • full/half duplex
   • Problems w/sending data using electricity
     • distance
     • EMI
   • Ethernet LANs example
     • IEEE Standards
       • 10BASE-T/100BASE-T, etc...
     • UTP cables
     • Bit rate and encoding
     • RJ-45 connectors snd Sockets

2. Sending Bits with light and fiber optic cables

3. Sending Bits with radio waves and no cables
