RDP Remote Desktop Protocol, a protocol developed by Microsoft as an extension

to the ITU T.128 and T.124 video conferencing protocol. With RDP, a PC sys-

tem can be controlled from a remote location using a network connection over

which data is transferred in both directions. Typically graphics updates and au-

dio are sent from the remote machine and keyboard and mouse input events are

sent from the client. VirtualBox contains an enhanced implementation of the

relevant standards called “VirtualBox RDP” (VRDP), which is largely compatible

with Microsoft’s RDP implementation. See chapter 7.4, Remote virtual machines

(VRDP support), page 99 for details.

SATA Serial ATA, an industry standard for hard disk interfaces. See chapter 5.1, Hard

disk controllers: IDE, SATA (AHCI), SCSI, page 76.

SCSI Small Computer System Interface. An industry standard for data transfer be-

tween devices, especially for storage. See chapter 5.1, Hard disk controllers: IDE,

SATA (AHCI), SCSI, page 76.

SMP Symmetrical Multiprocessing, meaning that the resources of a computer are

shared between several processors. These can either be several processor chips

or, as is more common with modern hardware, multiple CPU cores in one pro-

cessor.

UUID A Universally Unique Identiﬁer – often also called GUID (Globally Unique Iden-

tiﬁer) – is a string of numbers and letters which can be computed dynamically

and is guaranteed to be unique. Generally, it is used as a global handle to iden-

tify entities. VirtualBox makes use of UUIDs to identify VMs, Virtual Disk Images

(VDI ﬁles) and other entities.

VM Virtual Machine – a virtual computer that VirtualBox allows you to run on top of

your actual hardware. See chapter 1.2, Some terminology, page 11 for details.

VRDP See RDP.

VT-x The hardware virtualization features built into modern Intel processors. See

chapter 3.4.3, “Acceleration” tab: hardware vs. software virtualization, page 49.
