VirtualBox and Virtualization Key Terms

20 Vocabulary flashcards covering virtualization concepts, Oracle VirtualBox features, networking modes, and VM management as described in the lecture notes.

Virtualization

The process of creating a virtual version of hardware resources, allowing multiple operating systems to run on a single physical machine and improving hardware utilization.

VirtualBox

Free, open-source virtualization software that lets you run multiple guest operating systems on a single host and supports Windows, Linux, macOS, and Solaris.

Cross-platform

VirtualBox runs on Windows, macOS, Linux, and Solaris hosts.

Guest Additions

A set of enhancements that improve the performance and usability of guest operating systems within VirtualBox.

Snapshot

A point-in-time image of a VM's state (disk, memory, settings) used for backup, testing, rollback, and development.

Shared Folders

Feature that enables file and folder sharing between the host and guest operating systems.

Remote Display

Capability to connect to a running virtual machine from a remote location.

NAT (Network Address Translation)

Networking mode where the VM uses the host's IP to access external networks and is invisible to the local network.

Bridged Networking

Networking mode where the VM appears as a separate physical device with its own IP on the network.

Internal Networking

Networking mode where VMs can communicate with each other and the host, but are isolated from external networks.

Host-Only Networking

Networking mode where VMs can communicate with each other and the host, but cannot connect to external networks.

NAT Network

A NAT-based network mode that allows multiple VMs to communicate with each other while using the host for external connectivity.

Cloning

Creating an exact duplicate of a VM, including disks and settings, for testing, isolation, parallel testing, or versioning.

Virtual Machine (VM)

A software-based emulation of a computer system that runs inside VirtualBox.

Host Machine

The physical computer on which VirtualBox is installed and runs.

Guest Operating System

The operating system installed inside a virtual machine (e.g., Windows, Linux, macOS, Solaris).

Supported Guest Operating Systems

The range of guest OSs VirtualBox supports, including Windows, Linux, macOS, Solaris, and others.

Host Operating System

The operating system on the host computer that VirtualBox runs on (e.g., Windows, macOS, Linux, Solaris).

Hardware Requirements

Minimum specifications to run VirtualBox: x86/x86-64 CPU, at least 2 GB RAM, about 200 MB for the application, and SSD and space for VMs.

SSD (Solid-State Drive)

A solid-state drive recommended for better VirtualBox performance and faster VM storage.
