broadband
This term describes the technical ability to carry multiple signals and a vast amount of data simultaneously. It suggests a wide pipe of information, contrasting with the narrow, slow connections of the dial-up era. In modern conversation, it is almost exclusively synonymous with high-speed internet access rather than the technical physics of frequency bands. While a technical term, it is used casually in consumer contracts and government policy discussions. It carries a connotation of modernity and essential infrastructure, similar to how electricity or running water are viewed in a developed society.
Uncountable when referring to the general technology or service (Broadband is slow today). Countable when referring to a specific subscription or physical line (We have two broadband connections in the house).
