‘Broadband’, ‘DSL’, ‘SDSL’, ‘ADSL’ and ‘ADSL2+’ are all types of line connection to a public telecommunications network for high speed internet access.
The term ‘broadband’ is generally applied to any type of high speed internet access line. Thus all types of ‘DSL’, ‘ADSL’ and ‘ADSL2+’ lines are also ‘broadband connections’. ‘Broadband’ might also be used to describe high speed Internet acess via Cable TV network (in this case not using ‘DSL’ technology).
