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 the resources of the
host PC using NComputing vSpace software and a PCI card containing a system-on-a-
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 performing backup and recovery
tasks.
Download: the network transmission of a file from one computer system to another.
Ethernet: the most widely-installed local area network (LAN) technology - specified in a
standard, IEEE 802.3.
Firewall: a set of related programs that protect the resources of a private network from
users on other networks and control what outside resources local users have access to.
Gateway: a network point that acts as an entrance to another network. On the Internet,
a node can be either a gateway node or a host (end-point) node.
Host PC: a computer in which the vSpace software has been installed.
Internet: a worldwide system of computer networks in which users at any one computer
can, if they have permission, get information from other connected computers (and
sometimes talk directly with users at other computers).
LAN: local area network (LAN) is a group of computers and associated devices that
share a common communications line or wireless link and typically share the resources
of a single processor or server within a small geographic area (for example, within an
office building). Usually, the server has applications and data storage that are shared in
common by multiple computer users. A local area network may serve as few as two or
three users (for example, in a home network) or as many as thousands of users (for
example, in an FDDI network).
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
access to the OS or application. Almost always, a logon requires that the user has (1) a
user ID and (2) a password. Often, the user ID must conform to a length requirement,
such as eight characters or more, and the password must contain at least one digit and
not match a natural language word.
User: a person who uses a computer system. Users need to identify themselves to be
able to 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 to a computer via a standardized interface socket. USB allows
devices to connect and disconnect from a computer without forcing the computer to be
restarted.
