internet connection methods 1
  1. Connection method
    1. Wireless
      1. Broadband
        1. Dial-up
    2. Description
      1. Used by wireless-enabled devices (computers, mobiles, smartphones, etc.) to log in to the internet. Wireless is exactly what it says; there are no wires to connect.
        1. A wired connection to a broadband supplier. Normally the connection is via a network card in the computer. Cable users have an ethernet connection from their computer to the network.
          1. A wired connection via a conventional telephone line, which needs a modem to convert signals to and from analogue for transmission
      2. Advantages
        1. Not fixed to a stationary computer. Can be used wherever there is a wireless hub which is accessible.
          1. Broadband connections can give better reception and are usually faster than dial-up
            1. Can use existing telephone circuits which is useful in some areas
        2. Disadvantages
          1. Need to have access to a wireless hub. Can be less secure than wired connections. Tend to have slower data transmission speeds than wired broadband methods.
            1. Requires a base which is wired in, so it is less flexible than wireless.
              1. Older technology gives poor reception at times. The conversion from digital to analogue signals can cause errors. Tends to be slower than other connection methods.
          2. Bandwidth and transmission rate Bandwidth is a measure of the available capacity of a network (to carry data) measured in bits per second. The transmission rate is a measure of the number of pieces of information that have been transferred during a specific time period, usually also measured in bits per second. A high bandwidth means more information can be carried in a given time, so a higher transmission rate is achieved. Insufficient bandwidth can result in websites and servers appearing to run very slowly.
