Red Hat, Linux and Ubuntu are all the same?

Red Hat Enterprise Linux

• Is not free, and its also used for business. Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system.
• It is best for server purpose used and for enterprise.
• Red Hat uses RPM package manager.

Ubuntu

• Is free.
• Is a Linux distribution that starts with the breadth of Debian and adds regular releases (every six months), a clear focus on the user and usability (it should “Just Work”, TM) and a commitment to security updates with 18 months of support for every release.
• It is best for home based Desktop user.
• Ubuntu uses the dpkg (Debian) package system.

Due to its differing packaging system, Ubuntu is expected to be more flexible and easier to implement. That's why I will prefer to use Ubuntu.

Linux

• Linux is operating system like other operating system windows.

Windows: Windows 98, Windows XP, Windows Vista, Windows 7

Linux: Ubuntu, Debain, Fedora, Redhat, CentOS

Red Hat, Linux and Ubuntu are all the same?

Red Hat and Ubuntu are both Linux operating systems. These two are part of the different distros or distributions of the Linux platform. These distributions are just like with Microsoft Windows that has different versions: Windows 3.x, Windows 95, Windows 98, Windows 98 Second Edition, Windows Millennium, Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8.x, and Windows 10.

With Linux, it is available in different distros or flavors: Arch Linux, CentOS, Debian, Fedora, Gentoo Linux, Linux Mint, Mageia, openSUSE, Raspbian, and Ubuntu. These are the most popular and mainstream distributions of the Linux platform plus the commercial distros like Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Linux is a series of free, open-source operating systems developed around the Linux kernel.

Linux is usually packaged in a form known as Linux distribution or distro designed for both desktop and server use. The Linux kernel is the defining or significant component of a Linux distribution. It is an operating system kernel originally released by Linus Torvalds on September 17, 1991.
