Glossary

C

COM

Microsoft Component Object Model, a programming infrastructure for modular

software. COM allows applications to provide application programming inter-
faces which can be accessed from various other programming languages and
applications. VirtualBox makes use of COM both internally and externally to
provide a comprehensive API to 3rd party developers.

D

DHCP

Dynamic Host Configuration Protocol. This allows a networking device in a

network to acquire its IP address (and other networking details) automatically,
in order to avoid having to configure all devices in a network with fixed IP ad-
dresses. VirtualBox has a built-in DHCP server that delivers an IP addresses to
a virtual machine when networking is configured to NAT; see chapter

interface”, in the context of VirtualBox, we sometimes refer to the main graphical
VirtualBox

program as the “GUI”, to differentiate it from the VBoxManage

interface.
