What are the download speeds for BT Broadband?

Broadband speeds or 'bandwidth' indicates how much digital information in the form of binary digits, bits can be received over the line. Speed and bandwidth are measured in thousands (kilobits) or millions (megabits) of bits per second and are commonly shown as K, Kbps or Kbit/s and M, Mbps or Mbit/s.

 

Different speeds suit different purposes. Live action audio and video requires much greater bandwidth to be received as intended than downloading static documents from a website. Broadband is widely offered at peak speeds of 1Mb ('Known as 1 meg', the most common choice for home and small business use), 3072K (3Mb) and 7616K (7.6Mb).

 

The download speeds for BT Broadband are as follows:

 

BT Broadband Option 1Up to 1Mb connection, i.e. 1024 Kilobits/Sec. This makes it possible to download a file from the Internet at a transfer rate of approximately 100+ Kilobytes/Sec. **
