There's nothing really unique about Linux's licensing, it's just the GPL version 2.
However it is regarded as unique among operating systems where operating systems tend to be walled off, highly proprietary bundles of software that, in some cases, users aren't even allowed to modify or replace.
Linux, on the other hand, is all about letting you give it away, change what you want, even get rid of it if you want to.

Nothing. The GPL is not a license you purchase. It is legal to sell Linux distributions, but most (Except for Red Hat Enterprise and a few others.) don't cost a thing and are free to download.
The use of the Linux bandwidth monitor is the way to properly monitor network traffic with reports. They use these to know the bandwidth unique usage.
unix and linux systems are true multi user (root + others) but in windows admin and main user are same !
In general Linux has no restrictions on the number of users in a server. Commercial Unix vendors vary in what they allow by licensing, so it depends on the vendor.
Because that's what the most of the people who develop and distribute it are willing to charge for it. The licensing of Linux actually doesn't stop anybody from selling it for whatever price they want.
Because it's free, open-source, can be modified and used as desired without licensing issues in most scenarios.
Strictly speaking, it isn't a matter of what Linux can do and what others cannot; most of the software available for Linux was written for older ones or has been ported. What is special about Linux is its low cost and its high performance compared to other common alternatives.
Open-source software refers to software that that has licensing terms that allows modification and distribution.
Linux is licensed under the GPL. This means that if you use the kernel in one of your products, you must release any changes that you made. You can use proprietary modules, but these are restricted in what they are allowed to do. Only freely licensed modules can access all features of the kernel.
