Broadband refers to a high-speed Internet transmission (usually 256Kbps and above) featuring a permanent connection. The most common ways of getting online with broadband are via your TV cable box, your satellite or via your phone line. Cable TV is an easy option, but the most common type of broadband access is through an upgraded home telephone line called ADSL (Asymmetrical Digital Subscriber Line). ADSL is always connected so needn't be dialed up each time, and you can make phone calls on the same line while it's being used.
