What is a virtual machine?
Answer / Pradeep Kumar Gautam
A virtual machine (VM) is a software emulation of a physical computer that runs an operating system and applications as if it were actual hardware. VMs help create isolated, independent environments to run different operating systems or applications on the same physical host without interfering with each other. They are commonly used in blockchain nodes like Ethereum's Geth client, which utilizes a VM called the Ethereum Virtual Machine (EVM) to execute smart contracts.
