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
, page
for details.
S
SATA
Serial ATA, an industry standard for hard disk interfaces. See chapter
disk controllers: IDE, SATA (AHCI), SCSI
, page
SCSI
Small Computer System Interface. An industry standard for data transfer be-
tween devices, especially for storage. See chapter
, page
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.
U
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.
V
VM
Virtual Machine – a virtual computer that VirtualBox allows you to run on top of
your actual hardware. See chapter
, page
for details.
VRDP
See RDP.
VT-x
The hardware virtualization features built into modern Intel processors. See
