Broadband and Bandwidth.


  1. What is broadband?
    Broadband Internet access, often shortened to just "broadband", is a high data rate connection to the
    internet.
  2. What units are used to measure bandwidth?
    bits (b or bit), kilobits (kb or kbit), megabits (Mb or Mbit), gigabits (Gb or Gbit) or megabytes (MB), megabytes per second (MBps or mbps or Mbps) and megabits per second (Mbit/s or mbps or Mbps). There are approximately 1000 kilobits per one megabit and there are eight bits (b) per byte (B). (Which means a megabyte is much much bigger than a kilobit).
  3. How much faster is broadband than dial up?
    1000 mega bits per second.
  4. What are the speeds that broadband operates at compared to dial up?
    Dial up is considered to be just below a megabit per second and broadband can go from over 1 megabit per second to over 1000 megabit per second.
  5. What are some of the advantages of using a broadband connection to download something like a video compared to a dial up?
    Connection speed is up to 100 times faster than dialup connection.  You can download pictures files, software in seconds or minutes instead of hours.  Online gaming is only possible using a broadband internet access. Compared to the dial up it does not have a wide range of frequencies that can be transferred through the internet.
  6. Create an image on paint that illustrates how a high bandwidth connection can move more data compared to a dial up connection at a given time.
