CSMA/CA - Carrier Sense Multiple Access with Collision Avoidance


DHCP - Dynamic Host Configuration Protocol. This protocol automatically

configures the TCP/IP settings of every computer on your home network.

DNS - DNS stands for Domain Name System, which allows Internet host

computers to have a domain name (such as www.smc.com) and one or more IP
addresses (such as 192.34.45.8). A DNS server keeps a database of host

computers and their respective domain names and IP addresses, so that when a
domain name is requested (as in typing " www.smc.com" into your Internet

browser), the user is sent to the proper IP address. The DNS server address

used by the computers on your home network is the location of the DNS server
your ISP has assigned.


DSL - DSL stands for Digital Subscriber Line. A DSL modem uses your existing

phone lines to transmit data at high speeds.

Ethernet - A standard for computer networks. Ethernet networks are connected

by special cables and hubs, and move data around at up to 10 million bits per
second (Mbps).


ESS - ESS (ESS-ID, SSID) stands for "Extended Service Set". More than one BSS

is configured to become an Extended Service Set. LAN mobile users can roam

between different BSSs in an ESS (ESS-ID, SSID).

Fast Ethernet NIC - Network interface card that is in compliance with the IEEE
802.3u standard. This card functions at the media access control (MAC) layer,

using carrier sense multiple access with collision detection (CSMA/CD).


Fixed IP – (see Static IP)


Full-Duplex - Transmitting and receiving data simultaneously. In pure digital

networks, this is achieved with two pairs of wires. In analog networks, or digital

networks using carriers, it is achieved by dividing the bandwidth of the line into
two frequencies, one for sending, one for receiving.


Hub - Central connection device for shared media in a star topology. It may add

nothing to the transmission (passive hub) or may contain electronics that

regenerate signals to boost strength as well as monitor activity (active/intelligent
hub). Hubs may be added to bus topologies; for example, a hub can turn an

Ethernet network into a star topology to improve troubleshooting.

ID3 – The data fields in an MP3 that hold the artist name, track titles, album

titles, genre, etc are known as ID3 tags.
