Ubuntu is one of many linux distributions, similar to windows in xp, vista
inux is a set of Unix-like operating systems that are free to use and spread freely. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX .

Easy-to-use virtual machine software for mac system
VMWare Fusion and Parallels Desktop perform much better than VirtualBox.
VMWare Fusion lagged behind Parallels Desktop in previous years, but now it seems to have surpassed it by many metrics. However, I haven't used VWF for a long time, and I don't know how convenient the function is compared to PD.
Parallels Desktop upgrades are expensive, VWF seems to be cheaper. But if you buy a new license, the price of the two is not much different. If you are a college student, you can buy a cheaper new license of Parallels Desktop on the Xaar Campus Pioneer.
The advantages of PD over Virtual Box:
1. Support NTFS read and write, no need to buy ParagonNTFS separately, save 100 yuan;
2. The identification of USB devices is relatively intelligent;
3. Integrate the shortcut to open IE in Safari, making it more convenient to visit websites using old technology.
VirtualBox for mac is a powerful virtual machine system software that not only has rich features, but also is very powerful and has excellent performance.
VMware Fusion for mac is a virtual machine software on the Mac operating system that helps users run Windows systems on the Mac platform.
Parallels Desktop is a proven, trusted and proven solution for running Windows applications on your Mac. With Parallels Desktop 10, you can run both Windows and Mac OS X seamlessly
