Also known as Network Administrator. It is the name for a system administrator in a network who has unrestricted rights of access and is responsible for the administration and upkeep of the networks.
ADSL
"Asymmetric Digital Subscriber Line", a technology for transmitting digital information over standard telephone lines which allows high-speed transmission of signals from the telephone network to an individual subscriber, but a slower rate of transmission from the subscriber to the network.
Application / Application program
A program or piece of software designed and written to fulfil a particular purpose of the user such as text processing and table calculation.
Application Streaming
Application streaming is a form of on-demand software delivery/distribution. It takes the advantage of the face that only a small fraction of a computer program need to be available for the end user to perform a particular function. In this way, a program need not be fully installed, but parts of it can be delivered over a low bandwidth network as and when they are required.
Asset Management
Asset Management manages inventory in a physical and operational sense. It is the set of business practices that join financial, contractual and inventory functions to support life cycle management and strategic decision making for the IT environment. Assets include all elements of software and hardware that are found in the business environment.

D
DHCP
"Dynamic Host Configuration Protocol". The DHCP automatically assigns IP addresses to connected Clients from an established area of IP Addresses and thus saves a lot of configuration work with larger networks. In addition to an IP address, a client also receives additional information, such as the address of the Gateways (Routers) and the address of a competent name server (DNS).
To be able to centrally manage the issuance of addresses and setting of parameters, the Internet Engineering Task Force (IETF) has designed the Dynamic Host Configuration Protocol (DHCP), that offers three procedures:
With automatic address issuance, the DHCP Server selects for the computer any permanent IP number on first registration.
The dynamic procedures issue temporary IP code words with each login of a computer. If a client no longer needs the address, then he returns it. The DHCP Server can then assign it to another computer.
Finally, the manual configuration allows the administrator to assign a certain IP address explicitly to one computer. In such a case, DHCP is only used as a transport medium.
Moreover, DHCP represents an expansion and further development of the Bootstrap Protocols (BOOTP), that was primarily used for the connection of diskless workstations to a TCP/IP network, so as to assign them an IP address at the start.
Digital Signage
Digital signage is a form of electronic display that shows information, advertising and other messages. Digital signs (such as LCD, LED, plasma displays, or projected images) can be found in public and private environments, such as retail stores and corporate buildings.
DSL
"Digital Subscriber Line Technology". DSL offers technology to operate the Internet with more MBits per second over copper lines. Also see PPoE.

M
MAC / MAC Address
Abbreviation for "Media Access Control". Access procedure to the actual medium (cable) of a network that is implemented in the network controller - or rather, as an example, in the network card. This card has a so-called MAC address (or hardware address), whereby a station is clearly identified in the network. Network addresses (such as IP addresses) are always depicted at MAC addresses for actual data exchange. The MAC addresses are stored, with network cards and other devices, in a nonvolatile memory device and are unambiguous worldwide for each device; this, in other words, concerns the unmistakable series number of a network device. The addresses are made up of 48 Bits. These are normally represented as 6 hexadecimal numbers: for example: 00-30-67-34-00-1A. The first three hex numbers indicate a manufacturer code (here 3Com). The remaining numbers are used internally for codification purposes.
Data packets in the network are always sent via the MAC address, while all other kinds of addressing must always be converted to this hardware address.

S
SaaS
SaaS is short for Software as a Service. It delivers software and its functions as web-based services which can be accessed remotely by users. SaaS allows organizations to access business functionality at a cost-effective way comparing with licensed applications, since the price of SaaS is based on a monthly fee. Also, because the software is hosted on a centralised server, users don't need to invest in additional hardware. SaaS removes the need for organizations to handle the installation, set-up and often daily upkeep and maintenance.
Server Farm
It is also called "Server Cluster". It refers to a group of servers which are hosted in a single location. In a business network, a server farm might perform such services as providing centralized access control, file access, printer sharing, and backup for workstation users. The servers may have individual operating systems or a shared operating system and may also be set up to provide load balancing when there are many server requests. In a server farm, if one server fails, another can act as backup.
Solid State
Solid State, also called solid-state electronics are those circuits or devices built entirely from solid materials and in which the electrons, or other charge carriers, are confined entirely within the solid material.

T
TCP/IP
Transport Control Protocol / Internet Protocol, A protocol managing the transport of data packages on the internet.
Terminal
Data display device that is connected to a large and/or central computer; data storage occurs via the central computer. The terminal has a screen, keyboard and mouse. Printers may also be connected. It does not, however, have a computing unit. Computing activities are assumed by the central computer.
Terminal Server
The Windows NT Terminal Server (WTS) is an expansion that makes Windows NT Multi-User-capable. WTS allows access to Windows programs from a Client computer. And remote access (loosely translated "distant access") is made possible from outside locations via the Internet on centrally installed applications.
Microsoft purchased this technology from Citrix. The MultiWin technology licensed by Citrix forms the basis for the MultiUser functionality of terminal servers. Windows Terminal Server moreover contains RDP (Remote Desktop Protocol), a special protocol for remote linkage of Windows end units to the terminal server.

V
VGA
VGA (Video Graphics Array) is a basic standard for color resolution in computer monitors that, today, represents the lowest common denominator for compatibility. For example, when a computer boots into the Microsoft Windows operating system, the opening splash screen or Windows logo is presented in VGA mode using a palette of 32 colors and a resolution of 640 x 480. Once the system is fully loaded, the video card's device driver takes over at a higher resolution.
Virtual PC
Virtual PC is a program that emulates Windows, Linux or other operation systems on a PC or thin client which is equipped with sufficiently fast processor(s) . With Virtual PC installed, a device can show the desktop for the emulated operating system on one part of the display or it can take up the entire screen. You can run any program that will run under the other operating systems.
Virtualisation
In computing, virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources.
VNC
VNC is a remote service program. VNC enables you to remotely control a computer via a network connection, so as for example to access a remote computer, as if you were seated directly in front of it.

W
Wake on LAN
Switching on the PC through the network. The IGEL Remote Management Software is capable of sending a certain data packet to the MAC Address of the client that is to be switched on. The client itself is in a so-called "soft-off-status" - the power supply is not completely switched off, but instead the network component still at least supplies the network card with power. Here, it is important, since it concerns a normal network broadcast, for the router and available network structure to forward these packets appropriately.
Wi-Fi
"Wireless Fidelity". It's a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections.
Windows CE
Mircosoft operating system. Windows variant for Thin Clients Handhelds, etc. "Windows Powered". IGEL Clever Clients may be obtained with the MS Windows operating system CE 5.0.
