Glossary
Access device (XD2) : a multi-user computing station using NComputing patented
technology. It doesn't use a CPU, VGA, or main chipsets. It shares resources of the Host
PC using NComputing vSpace software and a PCI card containing a system on chip
(SoC).
Administrator
: a person who is responsible for managing a multi-user computing
environment, such as a local area network (LAN). Administrator responsibilities typically
include: installing and configuring system hardware and software; establishing and
managing user accounts; upgrading software; and backup and recovery tasks.

Gateway : a network point that acts as an entrance to another network. On the Internet,

Log on : Logon is the procedure by which an entity (person, program, or system)
exchanges credentials with an operating system or application in order to be allowed

such as eight characters or more, and the password must contain at least one digit and
not match a natural language word.

access the computer system. In order to ensure unique identities, the system
administrator usually assigns each user a username associated with a defined set of
computer resources.
USB : (Universal Serial Bus) is a standard designed to allow peripherals to connect and
identify themselves a computer via a standardized interface socket. USB allows devices
to connect and disconnect from a computer without the forcing the computer to be
restarted.
