Virtual Machine

A virtual machine, sometimes abbreviated as just VM, is an actual computer, just like a laptop, smartphone, or server. It is equipped with a CPU, RAM, discs for file storage, and an internet connection in case that is required.

VMs are frequently considered to be virtual computers or software-defined computers inside of real servers, although the components that make up your computer (hardware) are actual, physical, and exist solely as code.

By “borrowing” resources from a physical host computer, such as your personal computer, and/or a remote server, such as a server in a cloud provider’s datacenter, virtualization creates a software-based, or “virtual,” version of a computer with allocated quantities of CPU, memory, and storage.

A virtual machine is a computer file that functions like a real computer. These files are generally referred to as images. It can act as the user’s complete computer experience, as is typical on many people’s work PCs, or it can run in a window as a separate computing environment, frequently to run a different operating system. Since the virtual machine is partitioned off from the rest of the system, the host computer’s main operating system cannot be affected by the software running within a VM.

The Ethereum Virtual Machine (EVM), which is used to carry out smart contracts, is run by each node that makes up the Ethereum network. This occurs in a distinct sandbox, which offers the Ethereum platform significant security advantages by protecting it from DDoS (Distributed Denial of Service) attacks, which are a common tactic for hackers.
