DATA TRANSMISSION

1. WIRED NETWORKS

   • Parallel
     • Is where 8 Bytes of data travel at the same time over 8 different wires.
     • Is where 8 bytes of data travel over 8 separate wires
       • One advantage is that it is very fast
       • One disadvantage is that it is very expensive as it uses lots of wires
   • Serial
     • Synchronous
     • Asynchronous

2. WIRELESS NETWORKS

   • HOW DATA IS SECURED IN WIRELESS NETWORKS

3. INTERNET WITH TCP/IP

4. RELIABILITY AND SPEED OF DATA TRANSFER
