What is Virtual Machine

Virtual Machine (VM) is a software-based computer that runs inside a host system, allowing you to operate a different operating system such as running Microsoft Windows on a Mac seamlessly in a separate window just like any other application.

How Virtual Machines Work

The functionality of a VM is made possible by a software layer known as a hypervisor, which is responsible for creating, running, and maintaining the virtual environment. The hypervisor operates by sharing and allocating hardware resources specifically RAM, CPU, and storage from the host machine to the guest VMs.  

Benefits of Virtual Machine

• Run multiple OS: Allows running different operating systems such as setting a Linux OS in a Windows machine or vice versa and more.
• Hardware Savings: You can use applications designed for different systems without having to go out and purchase new physical computers.
• Isolated Environments: Each VM operates in its own isolated environment, preventing problems or malware within one VM from affecting other VMs or the host system.
• Cross-Platform Testing: Software engineers can easily test their applications across various operating systems to ensure they work for all target users.
