What is the quantity in the bid and ask size in TS 4.0?

Comrades:

Please, refresh my memory: what is the quantity in bid and ask size as
displayed on quote page in TS 4.0?
In my youth (Quotron machine) it was in 100 shares, that is bid size 10
means a 1000 shares bid at the bid price. Is it the same nowadays?

Thanks, Alex.
