This is entirely dependent on how the system is used. Most desktop Linux systems are likely to have one user on at a time.
Servers are more likely to have several on at a time, however.
For local (non-network) accounts, look at the /etc/passwd file. It contains all of the local users on that system. You can use many different commands such as less, more, cat, etc., to see the contents.
Finding software to help run cloud computing Linux can be difficult for some people. If you are new to using the Linux operating system, you may not know where to find the best computer networking software. Many software stores carry only a few networking software tools for Linux operating system users. If you look for software online, there are many more products for Linux users are retailers on the internet.
Many Linux distributions are intended for home users.
That depends on whether you are asking whether more people use Windows or Linux or which system supports more users. The maximum number of users in a modern Linux system is 4,294,967,295. Windows doesn't have any specific limit that has been published, but each account takes up a significant amount of space, limiting the number to well below the limit in Linux. As to how many people use them, more people use Windows on their personal computers than Linux.
Linux is not "based" on anything per se. Its kernel is all original code and the software included in the average Linux distribution is non-centric to a given system. However. Linux is inspired by and readily identified as being "related" to UNIX, to the point many Linux users consider it to be UNIX.
This is the problem, no one really knows. Unlike Windows or OS X, Linux doesn't really have you "register" or phone home to anyone, so no statistic on how many Linux users there are is accurate. I personally estimate Linux users number at least as much as OS X users, though many will not agree with me.
MicroSoft Windows - Windows 8 : Linux - Ubuntu 14.04 are two examples. Note: Linux is the name of the kernel, while Ubuntu is a distribution (distro) and is one of many Operating Systems available to Linux users for free.
Linux and the many variations based on Linux (Ubuntu, Mint, to name but two) are aimed at any one who wishes to use it, and is available for free.
Linux is an open source Kernel a key element in any operating system responsible amongst other things for managing memory. A Linux distribution is an operating system based on the Linux kernel, there are many Linux distributions. Please reword the question.
The 2.6 Linux kernel supports up to 4,294,967,296 user IDs. The 2.4 kernel only supports 65,536.
