Broadband

I asked my sister, any IT jargon that you'd like to know? She answered, broadband.

I am like... What?!

She challenged back, "See, you can't explain!"

"Broadband is high speed Internet."

"So, broadband is Internet?"

"It's high speed Internet."

Then I tried to mimic Jaring dialing sound. :D

I googled a bit, and found this article https://www.broadbandgenie.co.uk/broadband/help/beginners-guide-to-broadband. The dial-up connection is called "narrowband".
