'bandwidth-heavy' originates from the combination of 'bandwidth' and 'heavy', where 'bandwidth' refers to the data transfer capacity of a network, and 'heavy' implies a large or significant amount.

The term 'bandwidth-heavy' evolved from the increasing need to describe activities or applications that require substantial data transfer capacity.

Initially, it meant 'requiring a large amount of data transfer capacity', and this meaning has largely remained the same in modern usage.
