代写留学生英文题目：Ubuntu VM Lab
1. Create working environment for future labs
0 Learn what a virtual machine (VM) is
0 Install and configure VirtualBox
0 Install Ubuntu VM
2. Understand basics of working in Ubuntu
A virtual machine is a software that emulates a virtual environment on your machine. This entire virtual machine is (ideally) completely contained within the host machine that is hosting it.
As an example, if you are running a Windows 7 VM on a Mac, the Windows 7 VM should run exactly like a real Windows 7 on a machine. The operating system on VM does not know that it is being virtualized.
This allows us to run the same virtual machine on different computers, so when we run software on the same type of virtual machine we all get the same result. Virtual machine also allows any possible viruses on the virtual computer to be completely self-contained, leaving the host computer safe and unharmed by the viruses.
We will be using virtual machines in this class so that everyone has the same, safe environment to work on for future labs.
