hub.
Huba -a Aa huba isa similara toa switches,a buta oldera anda lessa secure.a Ita willa broadcasta alla packetsa toa
alla devicesa regardlessa ofa MACa address.a Thisa resultsa ina lessa bandwidtha anda isa lessa efficient.
Bridgea -a Aa bridgea cana createa aa singlea networka outa ofa multiplea networks.a Maya bea usefula ifa thea
cara dealershipa wasa aa largera chaina ofa dealerships.
Switcha -a Mosta routersa havea switches,a buta ana extraa switcha cana allowa fora morea wireda
connectionsa toa thea network,a whicha maya bea usefula dependinga ona thea amounta ofa staff.a Mosta
routersa area designeda witha aa limiteda amounta ofa ports,a asa littlea asa four,a soa evena aa smalla businessa
woulda eventuallya needa aa switch.a Mosta homea usersa area connecteda wirelesslya anda onlya needa aa
fewa wireda devices,a whicha typicallya aren’ta connecteda simultaneously.a Manufacturersa likea
Linksysa maya designa thea switcha toa stacka easilya ona aa routera toa maximizea space-efficiency,a sucha
asa thea SE4008a WRTa Switch.
Routera -a Aa routera managesa traffica betweena multiplea networks.a Ita willa createa thea mosta efficienta
patha fora traffica toa movea froma onea networka toa another.a Aa formera teachera ofa minea referreda toa ita
asa aa hallway.a Thisa willa bea requireda ina ordera toa connecta toa thea internet.
Modema -a Aa modema willa processa thea signala froma ISPa beinga carrieda overa cablea witha thea homea
network.a Thisa isa wherea thea routera willa bea connecteda to.a Essentiallya ifa youa onlya needa toa usea
onea wireda device,a youa woulda onlya needa aa router.
Gatewaya -a Essentiallya routesa traffica froma aa computera toa thea internet.a Ita isa similara toa aa routera
anda Ia havea seena thea terma hasa beena useda interchangeablya before.a However,a gatewaysa
specificallya willa routea traffica betweena twoa differenta networks.
Repeatera -a Aa repeatera cana boosta thea coveragea ofa aa wirelessa networka anda cana evena havea portsa
fora morea etherneta connections.a Thisa cana bea beneficiala fora aa largea buildinga wherea ana employeea

Ifa Ia hada toa guidea Susana ona howa toa upgradea thea networka ina thea officesa ata aa autoa dealership,a Ia
woulda tella hera thata ita isa aa processa anda certaina thingsa havea toa bea donea ina aa certaina order.a Firsta
shea willa needa toa makea surea thata shea hasa alla ofa thea equipmenta neededa toa makea thisa aa easya
transition.a Aftera researchinga thea commona architecturea devicesa Susana willa needa aa Huba whicha
connectsa multiplea wiresa froma differenta branches,a shea willa needa aa Repeatera whicha regeneratesa
thea signala overa thea samea networka beforea ita becomesa tooa weaka aftera extendeda timea periodsa ona
thea samea networks.a Shea willa needa Gatewaya whicha isa aa passagea thata connectsa twoa networksa
togethera witha twoa differenta networka models,a aa Bridgea whicha filtersa contenta bya readinga thea
MACa addressesa ofa destinationa anda sourcea ,a aa Switcha whicha isa meanta toa boosta efficiencya anda
performance,a aa routera whicha routesa dataa packetsa baseda ona IPa addressesa anda aa Broutera whicha
isa basicallya aa bridgea routera ita combinesa featuresa ofa botha thea bridgea anda router.a Aftera
gatheringa thesea itemsa shea shoulda bea gooda toa go.a Whilea upgradinga thea networka ina thea autoa
dealershipa office,a variousa componentsa needa toa bea integrateda toa makea thea networka
architecture.a Firstly,a therea isa aa needa toa usea devicesa thata cana helpa ina filteringa thea dataa soa thata
itsa overalla efficiencya cana bea increased.a Somea ofa thea maina elementsa thata musta bea considereda
includea hub,a bridge,a switcha anda router.
Huba a
Ina thea networka architecture,a thea huba woulda functiona asa thea centrala connectiona pointa fora thea
Locala Areaa Networka (LAN).a Aftera receivinga aa packet,a thea huba woulda transmita thea samea toa alla
thea portsa toa thea othera networkinga devices.
Bridgea a
Thea bridgea woulda bea responsiblea toa connecta anda passa thea packetsa betweena twoa networka
componentsa thata utilizea thea samea communicationsa protocol.
Switcha a
Aa switcha isa aa vitala elementa ofa thea networka thata isa primarilya responsiblea toa receivea
informationa froma aa sourcea thata isa connecteda toa it.a Furthera ita dispatchesa thea informationa toa thea
destinationa thata isa appointeda onlya .
Routera a
Thisa networkinga devicea isa responsiblea fora forwardinga thea dataa packetsa betweena thea computera
networks.a Ita carriesa outa thea traffica directinga activitya anda thusa directsa aa packeta ona itsa journeya
toa thea nexta network.
Eacha ofa thesea devicesa musta bea integrateda intoa thea networka architecturea ofa thea autoa dealershipa
office.a Guidinga Susana ona thisa processa shoulda bea commona sense.a Wea area goinga toa needa aa fewa
thingsa toa givea hera ana efficienta networka setup.a Thea twoa mosta importanta piecesa wea willa bea
usinga area goinga toa bea switches,a anda routers.a Thea switcha facilitatesa thea sharinga ofa resourcesa
betweena alla connecteda devices.a Thea routera isa whata isa useda toa gaina connectivitya toa thea internet,a
ita connectsa multiplea switchesa toa aa networka toa forma ana evena largera network.a Wea willa alsoa needa
aa huba soa thata wea area ablea toa connecta multiplea devicesa toa thea LAN.a Additionally,a outsidea ofa
thesea physicala piecesa ofa equipmenta wea woulda wanta toa recommenda toa oura frienda Susan,a toa
makea surea shea isa protecteda usinga hera networka setupa anda hasa somea sorta ofa softwarea ina placea toa
doa so.a Additionally,a wea coulda makea thea recommendationa thata ifa hera businessa grows,a shea maya
wanta toa investa intoa aa gateway.a Aa gatewaya isa useda toa connecta devicesa toa eacha othera ona
differenta networks.a Soa ifa shea openeda upa anothera officea anda neededa toa bea ablea toa havea accessa
toa devicesa ona botha networks,a fora filea sharinga purposes,a etc.a wea woulda installa thisa networka
gateway.a Ia woulda informa mya frienda ofa thea devicesa shea shoulda expecta toa seea witha hera officea
upgradea isa networka card(ifa needed),a hubs,a switches,a routersa anda networka software.a Ia woulda
informa hera ofa thea networka huba neededa toa bea thea centralizeda pointa toa transmita dataa froma onea
computera toa thea nexta asa wella asa networka switchesa whicha assignsa eacha computera ina thea
networka aa specifica maca addressa anda allowsa LANsa usinga aa networka switcha toa routea infoa toa
individuala computers.a Thea routera willa bea useda toa connecta networksa toa onea another,a anda wea
woulda wanta toa ensurea thata thea networka softwarea isa thea fastesta thata ita cana be,a securea anda
operatinga ata besta capacitya .a Ia woulda aska mya frienda ofa thea pricea rangea shea hasa ina minda toa spenda
fora thea upgradea anda leta hera knowa thata shea woulda bea lookinga ata 600a beinga thea low-enda rangea
toa geta alla ofa thea equipmenta requireda fora hera upgrade.a Thea firsta onea isa aa Hub.a Hubsa connecta
multiplea computera networkinga devicesa together.a Aa huba alsoa actsa asa aa repeatera ina thata ita
amplifiesa signalsa thata deterioratea aftera travelinga longa distancesa overa connectinga cables.a Thea
nexta onea upa isa switch.a Switchesa generallya havea aa morea intelligenta rolea thana hubs.a Aa switcha isa
aa multiporta devicea thata improvesa networka efficiency.a Thea switcha maintainsa limiteda routinga
informationa abouta nodesa ina thea internala network,a anda ita allowsa connectionsa toa systemsa likea
hubsa ora routers.a Routersa helpa transmita packetsa toa theira destinationsa bya chartinga aa patha
througha thea seaa ofa interconnecteda networkinga devicesa usinga differenta networka topologies.a
Routersa area intelligenta devices,a anda theya storea informationa abouta thea networksa they’rea
connecteda to.a Mosta routersa cana bea configureda toa operatea asa packet-filteringa firewallsa anda usea
accessa controla listsa (ACLs).a Thena thea nexta onea youa havea isa Bridges.Bridgesa area useda toa
connecta twoa ora morea hostsa ora networka segmentsa together.a Thea basica rolea ofa bridgesa ina
networka architecturea isa storinga anda forwardinga framesa betweena thea differenta segmentsa thata
thea bridgea connects.a Theya usea hardwarea Mediaa Accessa Controla (MAC)a addressesa fora
transferringa frames.a Ia woulda definitelya helpa mya frienda Susana witha upgradinga thea networka ina
hera office.a Upona doinga somea researcha thea maina thingsa Ia seea neededa area aa Hub,a Switch,a
Router,a Bridge,a Gateway,a Modem,a Repeater,a anda Accessa Points.a Youa cana finda thisa fora aa faira
pricea buta thea pricea cana alsoa bea higha dependinga ona thea qualitya anda specificationsa youa area
wanting,a ifa youa area settinga ita upa thea networka fora aa businessa youa wanta ita beinga secureda alonga
witha fast,a youa don'ta wanta aa slowa connectiona fora thea company,a whilea settinga thea upgradea upa
youa wanta everythinga isa secureda anda protecteda youa doa nota wanta anyonea beinga ablea toa messa
witha youra networka withina ora outa ofa youra company.a Ifa youa area goinga witha aa modem/routera thata
woulda bea morea reliablea fora youra businessa anda woulda providea bettera connectiona anda speeda
whicha isa aa greata thinga toa havea especiallya ifa youa area consistentlya sendinga emailsa backa anda
forth,a ora downloadinga filesa youa wouldn'ta wanta ita takinga forevera ora riskinga youra devicea nota
beinga ablea toa connect.a Aftera aa littlea bita ofa research,a Ia founda outa thata therea area 5a maina
componentsa useda ina youra averagea LAN.a Thesea 5a piecesa ofa equipmenta area router,a switch,a huba
,a firewall,a anda wirelessa AP.a Therea area alsoa lessa commona partsa thata cana sometimesa bea useda
sucha asa modems,a transcievers,a transponders,a bridges,a taps,a anda SFP'sa etc.a Aa routera isa aa devicea
thata communicatesa betweena thea interneta anda thea devicesa ina youra homea thata connecta toa thea
internet.a Asa itsa namea implies,a ita “routes”a traffica betweena thea devicesa anda thea internet.a Aa
networka switcha isa aa smalla devicea thata centralizesa communicationsa amonga severala connecteda
devicesa ina onea LAN.a Aa huba isa aa networka hardwarea devicea fora connectinga multiplea devicesa
togethera anda makinga thema acta asa aa singlea networka segment.a Aa firewalla isa aa featurea ona aa
networka thata blocksa ora preventsa unwanteda access.a Wirelessa accessa pointsa (APsa ora WAPs)a area
networkinga devicesa thata allowa Wi-Fia devicesa toa connecta toa aa wireda network.a Ia woulda thinka
thata Sallya wouldn'ta needa mucha morea thana aa Routera witha gooda rangea anda possiblya aa Wirelessa
accessa pointa woulda bea beneficiala fora hera customers.a Ifa mya frienda wasa wantinga toa upgradea
theira network,a anda wanteda mea toa overseea thea projecta herea isa whata Ia woulda suggesta ora looka outa
for.a Sincea thea networka isa alreadya ina place,a thena onea cana assumea certaina hardwarea isa alreadya
beinga utilizeda sucha asa patcha panels.a Ifa upgrading,a thea firsta questiona thata Ia woulda aska mya
frienda woulda be.a Area therea anya embeddeda systems,a hardware,a ora softwarea thata isa critical?a
Nexta Ia woulda thinka thata whoevera isa doinga thea upgradea woulda bea attemptinga toa makea ita morea
efficienta througha integratinga multiplea hardwarea devicesa intoa asa manya multi-functionala
devisesa asa possible.a Ifa thea networka usesa passivea hubs,a thena upgradea toa activea hubsa fora addeda
efficiency.a Hubsa cana geta pricey,a soa Ia woulda recommenda thea mid-levela smalla businessa modela
sucha asa thea Ciscoa WS-C3560cx.a Ita isa aa switcha anda huba combination,a anda retailsa fora $850.00a
ona serversupply.com.a Ia woulda looka toa routersa next.a Fora thisa Ia woulda goa witha aa Ciscoa c891f.a Ita
retailsa fora $550.00a ona AllHDD.com.a Ita isa harda toa knowa exactlya whata mya frienda needsa withouta
knowinga morea specifics,a buta Ia thinka ifa shea looksa towarda integration,a shea willa havea aa gooda
start.a Mosta networksa area smalla thinka ofa aa smalla officea ora homea anda evena largea networksa area
oftena divideda intoa smallera segments.a Thata smallera segmenta isa seta aparta froma thea largera
networka bya aa devicea thata cana filtera dataa anda helpa thea networka bea morea efficient.
Thesea werea foura devicesa thata filtera traffica area calleda connectivitya devices,a anda therea area
severala differenta types:
Bridge
Hub
Switch
Router
Aa solida understandinga ofa thea typesa ofa networka devicesa availablea cana helpa youa designa anda
builta aa networka thata isa securea anda servesa youra organizationa well.a However,a toa ensurea thea
ongoinga securitya anda availabilitya ofa youra network,a youa shoulda carefullya monitora youra
networka devicesa anda activitya arounda them,a soa youa cana quicklya spota hardwarea issues,a
configurationa issuesa anda attacks.a Controllinga traffic.a Largea networksa needa aa waya toa filtera anda
isolatea dataa traffic.a Connectivity.a Thesea devicesa cana connecta differenta typesa ofa networksa
usinga differenta typesa ofa networka protocols.a Hierarchicala addressing.a Segmentinga thea networka
witha connectivitya devicesa providesa ana actuala examplea ofa deliveringa actuala dataa toa thea righta
destinationa througha thea IPa address'sa networka IDa anda hosta ID.a Thea hubsa cana bea useda witha botha
digitala anda analoga data,a provideda itsa settingsa havea beena configureda toa preparea fora thea
formattinga ofa thea incominga data.a Fora example,a ifa thea incominga dataa isa ina digitala format,a thea
huba musta passa ita ona asa packets;a however,a ifa thea incominga dataa isa analog,a thena thea huba passesa
ita ona ina signala form.a Ina sensea ofa compacteda data.a Usinga switchesa improvesa networka
efficiencya overa hubsa ora routersa becausea ofa thea virtuala circuita capability.a Switchesa alsoa
improvea networka securitya becausea thea virtuala circuitsa area morea difficulta toa examinea witha
networka monitors.a Youa cana thinka ofa aa switcha asa aa devicea thata hasa somea ofa thea besta
capabilitiesa ofa routersa anda hubsa combined.a Aa maina devicea thata mya frienda coulda usea toa
analyzea theira networka area thea routersa becausea theya area general-purposea devicesa thata
interconnecta twoa ora morea heterogeneousa networks.a Theya area usuallya dedicateda toa special-
purposea computers,a witha separatea inputa anda outputa networka interfacesa fora eacha connecteda
network.a Becausea routersa anda gatewaysa area thea backbonea ofa largea computera networksa likea
thea internet,a theya havea speciala featuresa thata givea thema thea flexibilitya anda thea abilitya toa copea
witha varyinga networka addressinga schemesa anda framea sizesa througha segmentationa ofa biga
packetsa intoa smallera sizesa thata fita thea newa networka components.a Thea commona lista Ia founda anda
woulda tella mya frienda whicha devicesa toa expecta includea thea following.a Aa hub,a thea simplesta ina
networkinga connection,a allowsa botha analoga anda digitala connectionsa thata alsoa amplifya thea
signalsa thata wouldn'ta worka ina longera distances.a Nexta isa aa switch,a whicha isa aa morea precisea hub,a
willa boosta networka efficiencya anda willa reada thea addressesa ofa hardwarea viaa packetsa thata area
enteringa thea network.a Thea Router,a thea mosta commona ofa thea bunch,a allowsa packeta travela bya
usinga LANa anda WANa connectionsa asa wella asa youra firsta linea ofa defensea asa aa firewalla ina
connections.a Aa Bridgea willa connecta aa hosta toa anothera hosta ora networka segmentsa toa othera
segmentsa asa theya trya toa splita largera networksa intoa smallera easiera maintainablea networks.a Thea
aa Gateway,a usuallya actinga asa aa transport,a translatea thea functionsa betweena technologiesa whicha
helpsa makea mosta ofa thea processa autonomousa throughouta thea wholea process.a Thena thea
modem'sa rolea isa transmittinga digitala signalsa froma thea router,a intoa analoga signalsa bya telephonea
ora etherneta linesa toa furthera reducea thea stressa ofa multiplea connectionsa toa thea wirelessa networka
beinga ran.a Repeaters,a alsoa tieinga intoa aa hub,a amplifya thea signala ita receivesa toa transmita ata aa
highera levela ora powera toa furthera increasea thea rangea ofa thea connection.a Finally,a ana accessa
point,a involvinga wireda ora wirelessa connection,a isa aa securitya checkpointa ofa signalsa travelinga toa
anda froma thea router.a Througha researcha Ia founda thata thea commona networka devicesa area aa hub,a
switch,a router,a bridge,a gateway,a modern,a repeater,a anda accessa point.a Aa huba usa aa commona
connectiona pointa fora devicesa ina aa network.a Hubsa area devicesa commonlya useda toa connecta
segmentsa ofa LAN.a Thea huba containsa multiplea ports.a Whena aa packeta arrivesa ata onea port,a ita isa
copieda toa othera portsa soa thata thea segmentsa ofa thea LANa cana seea alla packets.a Thea switcha hasa aa
seta ofa inputa portsa wherea dataa messagesa comea ina anda aa seta ofa outputa portsa wherea dataa
messagesa area delivered.a Routersa area equippeda toa servea twoa maina functions,a processa routablea
protocolsa anda usea routinga protocolsa toa determinea besta path.a Aa bridgea isa aa devicea thata connectsa
anda passesa packetsa betweena twoa networka segmentsa thata usea thea samea communicationsa
protocol.a Bridgesa operatea ata thea dataa linka layera (layera 2)a ofa thea OSIa referencea model.a Aa
bridgea willa filter,a forwarda ora flooda ana incominga framea baseda ona thea Maca addressa ofa thata
frame.a Aa gatewaya isa aa nodea routera ina aa computera network,a aa keya stoppinga pointa fora dataa ona
itsa waya toa ora froma othera networks.a Thea moderna basicallya allowsa computera toa permanentlya
retaina largea amountsa ofa data.a Repeatersa area networka devicesa operatinga ata physicala layera ofa thea
OSIa modela thata amplifya ora regeneratea ana incominga signala alsoa knowna asa signala boosters.a Aa
accessa pointa isa basicallya isa aa wirelessa accessa point,a ora morea generallya justa accessa point,a isa aa
networkinga hardwarea devicea thata allowsa othera WIFIa devicesa toa connecta toa aa wireda network.a
Thea apa usuallya connectsa toa aa routera asa aa standalonea device,a buta ita cana alsoa bea ana integrala
componenta ofa thea routera itself.a Ia havea founda througha researcha youa cana geta alla thea componentsa
toa builda aa computera ona NEWEGG.com.a Aftera doinga mya researcha anda lookinga ata alla thea
optionsa fora thisa specifica typea ofa business.a Youa woulda firsta needa aa modema thata woulda supporta
thea amounta ofa employeesa usinga thea interneta anda alsoa somethinga thata hasa solida speeda anda
gooda reliability.a Mya recommendationa fora thisa woulda bea Netgeara C7100V.a Ita hasa botha gooda
speeda anda solida capabilitya toa supporta multiplea devicesa anda ita hasa gooda speeda thata waya thea
businessa runsa smoothly.a Nexta thinga youa needa isa aa routera toa takea thea signala anda disputea ita
betweena alla thea devicesa anda thisa isa importanta becausea ita isa howa thea interneta getsa toa youa fora
thema toa work.a Mya recommendationa woulda bea thea T-Pa Linka Archera A7.a Ita pairsa reallya wella
witha thea modema anda givesa thea besta optionsa fora speeda ana reliability.a Aftera theya havea thea
pairinga ofa modema anda routera youa nexta needa toa geta Etherneta cordsa toa distributea toa thea wholea
company.a Thesea helpa makea surea youa havea thea fastesta possiblea interneta connectiona anda makesa
surea itsa cleana anda crispy.a Aftera alla thata thea companya shoulda bea ablea toa runa smoothlya anda
properly.a Aftera aa littlea bita ofa research,a Ia woulda firsta recommenda aa fasta modem.a whicha isa whata
getsa youra analoga dataa anda makesa ita digitala fora youra routera toa senda toa youra computers.a ita isa thea
maina piecea ofa youra setup.a Witha aa bada modem.a youa willa bottlenecka youra wholea network.a Mya
