Usage

ハブ is most commonly used in transportation (ハブ空港(くうこう), hub airport) and technology (USBハブ, USB hub) contexts. It can also be used figuratively for any central point of activity or connection.

Not to be confused with

ハブ also refers to a venomous pit viper (波布(はぶ)) native to Okinawa, but that is a different word.
ハブる (slang) means 'to exclude someone from a group' and is derived from 省(はぶ)く, not from the English 'hub.'
