Glossary
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 93 for details.
S
SATA Serial ATA, an industry standard for hard disk interfaces. See chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 75.
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 75.
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 1.1, Virtualization basics, page 9 for details.
VRDP See RDP.
