Internet Definitions


(Q) Bridge
(A) A device which forwards traffic between network segments based on data link layer information. These segments would have a common network layer address.
(Q) HTTP
(A) Hypertext Transfer Protocol. The client-server TCP/IP protocol used on the World-Wide Web for the exchange of HTML documents. It conventionally uses port 80.
(Q) 1394
(A) IEEE 1394 AKA Firewire AKA iLink. A serial protocol that runs at speeds ranging from 100 to 400 megabits per second, depending upon the implementation. Devices that are prime candidates for IEEE 1394 include digital camcorders and VCRs, digital audio amplifiers, and video teleconferencing.
(Q) ADSL
(A) Asymmetric Digital Subscriber Line. A method for moving data over regular phone lines. An ADSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber's premises are the same (copper) wires used for regular phone service.
(Q) cable modem
(A) A modem that sends and receives data through a coaxial cable television network instead of telephone lines, and with a conventional modem.
(Q) CEBus
(A) Consumer Electronics Bus. A communications standard for in home networks developed by the Electronics Industry Association (EIA) and the Consumer Electronics Manufacturers Association.
(Q) Dynamic Host Configuration Protocol. A TCP/IP protocol that enables a network connected to the Internet to assign a temporary IP address to a host automatically when the host connects to the network
(A)
(Q) DNS
(A) Domain Name System. The system by which hosts on the Internet have both domain name addresses and IP addresses.
(Q) DOCIS
(A) Standard: Data Over Cable Service Interface Specification
(Q) DUN
(A) Dial Up Networking
(Q) G.Lite
(A) Universal DSL. Sometimes called "splitterless DSL."
(Q) HAPI
(A) Home API. An industry initiative in which Microsoft participates that focuses on device control. HAPI is a very high-level API that applications can use to control consumer electronics and home control devices on a network http://www.hapi.org
(Q) HLAN
(A) Home LAN (Local Area Network)
(Q) HomePNA / HPNA
(A) Home Phoneline Networking Alliance. HomePNA has been formed to develop specifications for interoperable, home-networked devices using the phone wiring already in place
(Q) HTML
(A) Hypertext Markup Language. The markup language used for documents on the World Wide Web. HTML is an application of SGML that uses tags to mark elements, such as text and graphics, in a document to indicate how Web browsers should display these elements to the user and should respond to user actions such as activation of a link by means of a key press or mouse click
(Q) ICS
(A) Internet Connection Sharing, often referring to the program built into may versions of Microsoft Windows
(Q) ICS
(A) Internet Connection Wizard - in Microsoft Windows
(Q) IEEE
(A) Institute of Electrical and Electronics Engineers, pronounced "I-triple-E." Founded in 1963, IEEE is an organization composed of engineers, scientists, and students. IEEE is best known for developing standards for the computer and electronics industry.
(Q) IIS
(A) Microsoft Internet Information Server. (web server)
(Q) IP address
(A) A 32-bit binary number that uniquely identifies a host (computer) connected to the Internet or to other Internet hosts, for the purposes of communication through the transfer of packets.
(Q) IR
(A) Infrared. Having a frequency in the electromagnetic spectrum in the range just below that of red light. Objects radiate infrared in proportion to their temperature. Infrared radiation is divided into categories based on wavelength
(Q) IrDA
(A) Infrared Data Association. The industry organization of computer, component, and telecommunications vendors who have established the standards for infrared communication between computers and peripheral devices such as printers.
(Q) ISA Bus
(A) ISA Industry Standard Architecture. An 8-bit (and later, a 16-bit) expansion bus that provides a buffered interface from devices on expansion cards to the PC internal bus.
(Q) ISP
(A) Internet Service Provider
(Q) LDAP
(A) Lightweight Directory Access Protocol. A network protocol designed to work on TCP/IP stacks to extract information from a hierarchical directory such as X.500. This gives users a single tool to comb through data to find a particular piece of information, such as a user name, e-mail address, security certificate, or other contact information.
(Q) LMHOSTS
(A) A text-based file used to locate remote computers for network file, printer, and remote access services. Used if WINS or DNS servers are not available on the network
(Q) VPN
(A) Virtual Private Network.
(Q) Router
(A) A device which forwards packets between networks. The forwarding decision is based on network layer information and routing tables, often constructed by routing protocols.
(Q) Packet
(A) The unit of data sent across a network. "Packet" is a generic term used to describe a unit of data at any layer of the OSI protocol stack, but it is most correctly used to describe application layer data units ("application protocol data unit", APDU
(Q) name resolution
(A) The process of resolving IP addresses to NetBIOS computer names
(Q) NAT
(A) Network Address Translation. Changes IP addresses in packets and edits needed IP header information "on the fly." Records the mapping between original and replacement addresses.
(Q) NIC
(A) Network Interface Card
(Q) PCI
(A) Peripheral Component Interconnect. A high-performance, 32-bit or 64-bit bus designed to be used with devices that have high bandwidth requirements, such as the display subsystem
(Q) PDA
(A) Personal Digital Assistants. A lightweight palmtop computer designed to provide specific functions like personal organization as well as communications. More advanced models also offer multimedia features. Many PDA devices rely on a pen or other pointing device for input instead of a keyboard or mouse. For data storage, a PDA relies on flash memory
(Q) POTS
(A) Plain Old Telephone Service.
(Q) PPP
(A) Point-to-Point Protocol. A data link protocol developed by the Internet Engineering Task Force for dialup telephone connections, such as between a computer and the Internet.
(Q) PPTP
(A) Point to Point Tunneling Protocol. Early (and widely deployed) tunneling protocol, partially superceded by L2TP.
(Q) RAS
(A) Remote Access Server
(Q) SMTP
(A) Simple Mail Transfer Protocol.
(Q) SNMP
(A) Simple Network Management Protocol.
(Q) USB
(A) Universal Serial Bus. A bidirectional, isochronous, dynamically attachable serial interface for adding peripheral devices such as game controllers, serial and parallel ports, and input devices on a single bus. (This serial protocol runs at 1-12 megabits per second.)
