AccessPoint:Anaccesspointisanintelligentnetworkdevicethatforwards
packetsbetweendifferentnetworksbasedonnetworklayeraddress
information,suchasIPaddresses.

DefaultGateway(Accesspoint):Everynon‐accesspointIPdeviceneedsto
configureadefaultgateway’sIPaddress.Whenthedevicesendsoutan
IP
packet,ifthedestinationisnotonthesamenetwork,thedevicehastosend
thepackettoitsdefaultgateway,whichwillthensenditouttowardthe
destination.

DHCP:DynamicHostConfigurationProtocol.Thisprotocolautomaticallygives
everycomputeronyourhomenetworkanIPaddress.

DNS
ServerIPAddress:DNSstandsforDomainNameSystem,whichallows
Internetserverstohaveadomainname(suchaswww.Broadbandaccess
point.com)andoneormoreIPaddresses(suchas192.34.45.8).ADNSserver
keepsadatabaseofInternetserversandtheirrespectivedomainnamesand
IPaddresses,sothatwhen
adomainnameisrequested(asintyping
"Broadbandaccesspoint.com"intoyourInternetbrowser),theuserissentto
theproperIPaddress.TheDNSserverIPaddressusedbythecomputerson
yourhomenetworkisthelocationoftheDNSserveryourISPhasassignedto
you.
 
DSLModem: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10/100
millionbitspersecond(Mbps).


IPAddressandNetwork(Subnet)Mask:IPstandsforInternetProtocol.AnIP
addressconsistsofaseriesoffournumbersseparatedbyperiodsthat
identifiesasingle,uniqueInternetcomputerhostinanIPnetwork.Example:
192.168.2.1.Itconsistsof2portions:theIPnetworkaddressandthehost

identifier.

TheIPaddressisa32‐bitbinarypattern,whichcanberepresentedasfour
cascadeddecimalnumbersseparatedby“.”:aaa.aaa.aaa.aaa,whereeach
“aaa”canbeanythingfrom000to255,orasfourcascadedbinarynumbers
