Which word can I use for this mean? I want to express the mean that"the internet charged by how many bytes you have used".Can I say"the internet charged by traffic"?Or which word can I used instead of "trafffic"? Many thanks in advance!

"hometown" and "home village" If my birth place is a village(not in town),what should I call it,"hometown" or "home village"?I am a little confused……

My Home Village Everyone has his unique hometown/home village,a place never same as another. My home village is a beautiful small village located at the foot of grand mountains in Shandong Province in North China.On the front are hilly land and mountains behind,a reservoir lays between the village and the mountains.A clear small river originates from the moutains and flows alongside the village.There are many small fishes,shrimps, crabs,mussels and other aquatic animals in the river.In the summer evening,frog sound is deafening,the sky studded with twinkling stars,so beauty let me lifelong unforgettable. I love my home village.
