Yes
Assuming you are referring to a gigabyte it is a billion bytes. That may be a lot or a little depending on the situation and use
Not much maybe ONE megabyte every time you visit the website, maybe even less, it depends, for example your browser usually stores most of the site in its memory, you wont use a gigabyte using facebook thats for sure, even if you use it for a year straight! INFO: 1 gigabyte= 1024 megabytes
not very much you can get a terrabite(1000gb) for like 100$ 40 gb is a lot depending on how you use it
It depends on what you are doing. If you download a lot of movies or music or take a lot of pictures, you can use a gigabyte in a few hours or a day. If you do nothing but type up word documents on your computer, you might not have over a gigabyte of typed documents in a year's time. Yes, it is possible to use a Gigabyte a month, it is also possible to use a gigabyte an hour or a gigabyte a year, it just depends on what you do on your computer and how you are using it.
it means you got a mesage gb
Your video size might be greater than 1024 mbs. You cannot upload a video of more than 1 GB of size on Facebook.

The 120 Gb is usually the best one to pick unless you are not going to use a lot of memory.
yes
The amount of internet activity (MB/GB) that are being used on your bandwidth depend on the game being played. For example, a browser game is not going to use a lot of bandwidth, while World of Warcraft may use a considerable amount of bandwidth.
It will run on 256Megabytes. But very slowly as it does a lot of disk swopping. Memory is cheap. Get 1 Gigabyte.
