Connectivity

1. Deep Sea Internet Cables

   • connected on land and under the ocean
   • Optical Fibres
     • Modern cables use optical fiber technology to carry digital data
       • speed of light
         • nearly 300,000,000 meters per second
   • Different colours show direction of flow
   • Good website to look into

2. The most connected places are America and Europe , America and China

3. Bandwidth

   • The amount of data that can be carried at a time
   • Maximum rate of data transfer across a given path
     • Network Bandwidth
       • Data transfer capacity of a network
     • Data Bandwidth
       • Maximum data transfer rate of a network or internet connection
         • measures how much data can be sent over a specific connection in a given amount of time
     • Digital Bandwidth
       • number of pulses per second measured in bits per second (bps)
