ADSLAsymmetric Digital Subscriber Line. A telephone line with a high download rate (up to 500 kbit/s) but a low upload rate (up to 50 kbit/s).
AFHAdaptive Frequency Hopping.
ANSIAmerican National Standards Institute.
APIApplication Programming Interface.
APIPAAutomatic Private IP Addressing. Allows computer to assign its own TCP/IP configuration settings.
ARPAddress Resolution Protocol. Translating IP addresses into physical hardware addresses. It is located in level 2 (Internet) of the DOD model, also supported by Windows CE. ARP writes to the addresses of network adapters, such as Ethernet controllers. Very important in all LAN connections.
APIApplication Programming Interface.
ATMAsynchronous Transfer Mode. Rapidly developing technology that embraces aspects of both WAN's and LAN's.

C

CCKComplemetary Code Keying.
CDMACode Division Multiple Access.
CODECCoder/Decoder.
CRCCycle Redundancy Check.
CIDRClassless Inter-Domain Routing: used in supernet models (multiple networks with separate IP addresses) for binding into a network, so that the IP address table can be compressed and limited. Reduces the size of the routing tables used by most Internet routers.
CSMACarrier Sense Multiple Access: listens for carrier before transmitting on a LAN.

DACDigital Access Code
DAMPSDigital Advanced Mobile Phone System
DECTDigital Enhanced Cordless Telephone
DHCPDynamic Host Configuration Protocol. DHCP provides dynamic assignment of a large number of IP addresses from applications for direct use in the Internet. It is installed as a DHCP server on Windows NT machines, where it extends the Administrator options. It is important if the webserver system has a Windows NT TCP/IP network server installed as an Internet station.
DOD Internet
Levels
Protocol
Layer
Department of Defense layer model incorporates TCP AND UDP in the transport layer. The application level (level 4) supports the FTP, HTTP, Telnet, NFS, SMTP, NNTP, SNMP and DNS protocols. The Internet level (level 2) supports IP,ARP, DCHP and ICMP, as well as RIP and OSPF.
DWDMDense Wavelength Division Multiplexing. DHCP provides dynamic assignment of a large number of IP addresses from applications for direct use in the Internet. It is installed as a DHCP server on Windows NT machines, where it extends the Administrator options. It is important if the webserver system has a Windows NT TCP/IP network server installed as an Internet station.

F

FCSFrame Check Sequence.
FDDFrequency Domain Duplex.
FDDIFibre Distributed Data Interface.
FDMAFrequency Division Multiple Access.
FERFrame Error Rate.
FHSSFrequency Hopping Spread Spectrum. A data signal is modulated by a carrier that hops from frequency to frequency as a function of time. A hopping code determines the sequence of frequencies used to transmit and the receiver uses the same code to change the receiving frequency.
FSKFrequency Shift Keying.
FTPFile Transfer Protocol. Transfers files between clients and servers that also allow a station to be externally controlled via the network or cable connection. FTP can be executed via TCP ports 20 and 21, even in command-line mode.

I

ICMPInternet Control Message Protocol. Protocol supports diagnostic messages, especially when a network, host or port is inaccessible.
IGMPInternet Group Management Protocol. Protocol organises groups of nodes and supports diagnostic and control messages in the network. Used by the ping command.
IMT2000International Mobile Telecommunications 2000.
InternetworkThe linking of several (local) networks to form a single network; not the same as the Internet.
IPInternetwork Protocol.
IPXInternetworking Packet Exchange.
IPX/SPXAn Internet/Novell standard that is equivalent to TCP/IP and is a protocol for the general Unix standard.
ISMIndustrial, Scientific and Medical radio band. A license exempt band at 2.4 to 2.483GHz. Divided into 13 channels in the UK and 11 in the USA.
ITUInternational Telecommunication Union. Formerly known as the CCITT (Comite Consultatif International Telephonique et Telegraphique).

N

NATNetwork Address Translation: converts a private network address into a global Internet address with a valid assignment. Very important for a webserver located in a LAN.
NetBEUINetBIOS Extended User Interface: a small but fast protocol developed by IBM and Microsoft in the mid-1980s. It is faster than TCP/IP and IPX/SPX and requires a small amount of memory overhead on each computer. Good for small networks, up to 50 computers.
NFSNetwork File Server: allows the file directories of external stations to be linked to a local file system; primarily suitable for Unix applications.
