Virtual Machine (VM)

A convenient server-based computer system with most of the capabilities of real computer systems.

A virtual machine (VM) is a server-based computer system with the majority of the features and capacities of real computers. These systems can also store and modify files, install and run software, and host websites. The difference between a VM and a normal computer system is that the former runs on a server whereas the latter is tangible. However, VMs are more useful than normal computers in that they act as isolated spaces where users can run programs without affecting the main operating system.

VMs are also getting frequent usage in crypto. The most common application is in Ethereum where the Ethereum Virtual Machine functions as a kind of parachain to assist user transactions, especially with smart contracts.
