Connectivity

1. undersea cables

   • America, China and Europe have more cables as people there use the internet more

2. bandwidth

   • amount of data that can be carried at a time

3. connection speed

   • mesured in mbps (megabits per second)
   • upload v download speed
     • download speed is faster because people download things more than uploading things

4. broadband

   • a high speed connection to the internet that has superseded the use of dial up connections

5. mesurements

   • 1MB (Megabyte) = 8Mb (Megabits)
   • Bit (b) = 0/1, Nibble = 4 bits, Byte (B) = 8 bits, Kilobyte (KB) = 8000 bits, Megabyte (MB) = 8,000,000 bits, Gigabyte (GB) = 8,000,000,000 bits, Terabyte (TB) = 8,000,000,000,000 bits, Petabyte (PB) = 8,000,000,000,000,000
