Install Virtual-box in Linux

 How to Install Virtual-Box in Linux?

Virtual Machine abstracts the hardware of our personal computers such as CPU, disk drives, memory, NIC (Network Interface Card), etc., into many different execution environments as per our requirements, hence giving us a feeling that each execution environment is a single computer. For example, VirtualBox. We can create a virtual machine for several reasons, all of which are fundamentally related to the ability to share the same basic hardware yet can also support different execution environments, i.e., different operating systems simultaneously.
