It has a CPU, memory, and a disk for storing files, and it can be connected to the Internet as needed. Although the various parts (hardware) that make up a computer are physical and tangible, a VM is usually considered to be a virtual computer or a software-defined computer in a physical server, only in the form of code.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-82353dc elementor-widget elementor-widget-heading\" data-id=\"82353dc\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">How does a VM work?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9c4a14a elementor-widget elementor-widget-text-editor\" data-id=\"9c4a14a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Virtualization is the process of creating a software-based or &#8220;virtual&#8221; version of a computer with dedicated CPU, memory and storage &#8220;borrowed&#8221; from a physical host (such as your personal computer) and a remote server-such as a cloud provider (the server in the business data center).<\/span><\/p><p><span style=\"font-weight: 400;\">A virtual machine is a computer file, usually called an image, which behaves like an actual computer.
