For women, it represents a more intimate approach to webcam sex that allows them to get to know a potential partner before taking things to the next level. Many of you know this site as the world's largest sex personals (which it is), but there is so much more to this service than meets the eye.
Skype also recommends different bandwidth requirements for different situations. HD video calling has a recommended upload and download speed of 1.5Mbps both ways so you are looking at about 22.5 MB per minute.
It's on our computers, our phones, our tablets and soon it will be on our gaming consoles.
Some of us even have Skype integrated into our large screen televisions.
To answer your last question as Skype is a peer to peer application and will try to make the best use of the bandwidth it has available so the rate is variable and not fixed. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
