The short answer is that Linux is a computer operating system, and is an alternative to older products such as DOS, Windows, MacOS or UNIX. The way that Linux is written and distributed is new and revolutionary - it is maintained by an open community of programmers and you can get it for free. This has created a growing industry of distributors who bundle Linux and other useful stuff into a distribution package or distro, to make life easy for the end user. This method of development and distribution is protected by an equally revolutionary license, the GNU Public License
Initially it was just called "Red Hat Linux", but now Red Hat focuses exclusively on the enterprise market with its Linux distribution named "Red Hat Enterprise Linux" (RHEL) with the community version named CentOS (Community ENTerprise Operating System) and Fedora (a Red Hat-supported community Linux distribution)

The Linux kernel was originally written by Linus Torvalds (Linux is only one letter away from Linus) Over time most of the Linux kernel has been modified by many people in the open source community, however Linus still oversees the project.
As far as I can tell, all the tax software I've seen online has been Windows or Mac based. It is possible that some of the online based programs can work on Linux, but this seems to be a general issue with the Linux community.
At the command prompt, type 'man [command]' (removing the brackets and substituting the command for which you need information).
It is an online community of new and seasoned Linux / Unix sysadmins who want to make the most of sysadmin-hood.
Ubuntu is a complete Linux-based operating system, freely available, with both community and professional support. And there are several alternatives, including OpenSUSE, PCLinuxOS, Freespire and Linux Mint.
"Yes, you can receive Linux training online, but you will have to be willing to pay the price of online teaching. You can also see if your local community college offers online class sessions."
It was not originally developed by any company, but a college student. And for a while it was a huge community collaborative project.
