In relation to wireless service provided by likes of 3, O2, and Vodaphone when the talk about monthly download allocation of 5 or 10 GB -what actually constitutes a download
Does opening an email from your hotmail/gmail count as a download
Does navigating to a web site and its pages/sub pages etc constitute as download
Or does a download mean something you physcially click on a download button for and physically select to save somethign to location on your computer
When you retreive any information from the net (e.g. viewing this page) you must download the information. So every single thing you do online (viewing a web page, viewing an e-mail, etc.) means you download a little.
The size of most web pages are so small that you use up very little of your cap, but it can all add up. Downloading software/programmes/etc. will obviously use up more in a far shorter time.
If you are sharing torrents they will be uploading in the background (as long as your torrent application is running in the background - they normally start automatically when you boot up.)
As someone else said, "normal" internet usage (browsing and e-mail) won't use anything near 5 or 10 gigs transfer.
I have found that remote controlling servers/desktops using remote desktop/vnc or dameware as part of working from home can use up huge chunks of your monthly limit.
