Glossary
Access device: a network computing device using NComputing patented
technology. It doesn't use CPU, VGA, and PC chipsets; it only uses a
programmable SoC to connect to a Host PC. An access device using
NComputing User eXtension Protocol (UXP) can be connected to Host PCs by
using the LAN cable. Also, it can be connected to remote PCs through the
Internet using TCP/IP.
Administrator: a person who is responsible for managing a multi-user computing
environment, such as a local area network (LAN). The responsibilities of the
system administrator typically include: installing and configuring system hardware
and software; establishing and managing user accounts; upgrading software; and
backup and recovery tasks.
Alias: a fictitious name used by an individual as an alternative to her or his true
name.
Client/Server: describes the relationship between two computer programs in
which one program, the client, makes a service request from another program,
the server, which fulfills the request.
Console: the text entry and display device for system administration messages,
particularly those from the
BIOS
or
boot loader
, the
kernel
, the
init
system and
the
system logger
.
DHCP: (Dynamic Host Configuration Protocol) is a communications protocol that
lets network administrators centrally manage and automate the assignment of
Internet Protocol (IP) addresses in an organization's network. Without DHCP, the
IP address must be entered manually at each computer in an organization and a
new IP address must be entered each time a computer moves to a new location
on the network.
Download: the 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 (located at a network gateway server) that
protect the resources of a private network from users on other networks and
control what outside resources its own users have access to. (The term also
implies the security policy that is used with the programs.)
Gateway: a network point that acts as an entrance to another network. On the
Internet, a node or stopping point can be either a gateway node or a host (end-
point) node.
Host Computer: a computer in which the vSpace program 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 any other computer
(and sometimes talk directly to users at other computers).
IP Address: the Internet Protocol (
IP
) is basically the set of rules for one network
communicating with any other (or occasionally, for broadcast messages, all other
networks). Each network must know its own address on the Internet and that of
any other networks with which it communicates. To be part of the Internet, an
organization needs an Internet network number, which it can request from the
