Zipangizo za Ethernet, ma-hubs, ndi kusintha kwake ndizodalirika kwambiri, makamaka chifukwa opanga makina akhala akupitilizabe zipangizo zamakono pa Ethernet zaka makumi angapo. Zingwe zosavuta zimakhalabe zowonjezereka komanso zowopsya chifukwa cholephera kuntaneti. Mukamayika LAN yowuma kapena kusuntha zigawo zonse mtsogolomu, onetsetsani kuti mukuyang'anitsitsa kugwirizana kwa chingwe .
Mabotolo a Broadband amakhalanso ndi mavuto ena odalirika m'mbuyomo. Mosiyana ndi zina zotengera Ethernet, zinthuzi ndi zatsopano, zipangizo zambiri.
Mabotolo a Broadband akhala akukula pazaka zingapo zapitazo ndipo kudalirika kwawo kwakula bwino kwambiri.
Kuchita
LAN zamakono zimapereka ntchito yabwino. Kuyanjana kwa Ethernet yachikhalidwe kumapereka mapeto a 10 Mbps okha, koma makasitomala a Fast Ethernet 100 Mbps amadula pang'ono ndipo amapezeka mosavuta. Ngakhale ma 100 Mbps akuyimira ntchito yaikulu yomwe sitingakwanitse kuchita, Fast Ethernet iyenera kukhala yokwanira kugawana mafayilo kunyumba , kusewera, ndi kuthamanga kwa intaneti kwa zaka zambiri m'tsogolomu.
LAN zogwiritsidwa ntchito pogwiritsa ntchito malowa zingathe kuchepetsa kayendedwe ka ntchito ngati makompyuta amagwiritsa ntchito intaneti nthawi yomweyo.
Gwiritsani ntchito kusintha kwa Ethernet mmalo mwa hubs kupeŵa vuto ili; kusinthana kumafuna ndalama zambiri kuposa chikhomo.
Chitetezo
Kwa LAN iliyonse yowongoka yogwiritsidwa ntchito pa intaneti, ziwombankhanga ndizo zogwiritsira ntchito zokhudzana ndi chitetezo. Zingwe zamtundu wa Ethernet ndimasinthasintha sichirikiza zowonjezera moto. Komabe, zopangidwa ndi pulogalamu yamakina a firewall monga ZoneAlarm akhoza kuikidwa pa makompyuta okha. Mauthenga a Broadband amapereka chofanana chowotchedwa firewall chimene chinapangidwa mu chipangizo, chosinthika kudzera pulogalamu yake.
Zambiri za LAN Zosakanikirana
Mafilimu otchuka a WLAN onse amatsatira imodzi mwa machitidwe akuluakulu atatu owonetsera Wi-Fi . Ubwino wa ma intaneti opanda waya umadalira pa ntchito yogwiritsidwa ntchito:
- 802.11b inali yoyamba yoyenera kugwiritsidwa ntchito kwambiri mu WLAN.
- Makhalidwe a 802.11a ali mofulumira koma okwera mtengo kuposa 802.11b; 802.11a amapezeka kwambiri muzinthu zamalonda.
- Miyezo yatsopano kwambiri, 802.11g , kuyesera kugwirizanitsa zabwino zonse za 802.11a ndi 802.11b, ngakhale iyenso ndi yokwera mtengo kwambiri pakhomo.
Kuyika
Ma Wi-Fi amatha kukhazikitsidwa m'njira ziwiri:
- Mawonekedwe a "Ad-hoc" amalola zipangizo zopanda mauthenga kuti zitha kuyankhulana ndi anzawo.
- Maselo othandizira "amachititsa zipangizo zopanda mauthenga kuti zitha kuyankhulana ndi mfundo yofunikira yomwe ingathe kuyankhulana ndi ma wired pa LAN imeneyo.
Ma LAN ambiri amafuna mawonekedwe opangira ma intaneti kuti apeze intaneti, makina osindikizira , kapena maulendo ena opangira mauthenga, pamene machitidwe ovomerezeka amathandizira zokhazokha zokambirana pakati pa zipangizo zamagetsi .
Mawindo onse a Wi-Fi amafuna makina osakaniza opanda waya, omwe nthawi zina amatchedwa WLAN makadi. Zolinga zamakono za WLAN zowonjezera zimafuna chipangizo chapakati chotchedwa access point . Malo oyenera kulumikiziridwa ayenera kuikidwa pamalo apakati pomwe mawotchi opanda mauthenga opanda waya angathe kufika nawo popanda kusokonezeka. Ngakhale kuti mawonekedwe a Wi-Fi amatha kufika mamita 30 kapena kuposa, zolepheretsa ngati makoma zingathe kuchepetsa kwambiri.
Mtengo
Zida zopanda waya zimakhala zochepa kwambiri kuposa zinthu zogwirizana ndi Ethernet.
Pa malonda okhutira, ma adapita opanda waya ndi malo otha kulumikizira angagulitse katatu kapena kanayi monga adapata zamtundu wa Ethernet ndi makina osinthika, motsatira. Zamakono 802.11b zatsika mtengo kwambiri ndi kumasulidwa kwa 802.11g, ndipo mwachionekere, malonda ogulitsa angapezeke ngati ogulitsa akulimbikira.
Kudalirika
Ma LAN opanda waya ali ndi mavuto ochepa kwambiri kuposa ma LAN wired, ngakhale mwina osakhala okhudzidwa kwambiri. 802.11b ndi 802.11g zizindikiro zopanda zingwe zimatha kusokonezedwa ndi zipangizo zina zapanyumba zomwe zimaphatikizapo mavuniki a microwave, matelefoni opanda zingwe , ndi zitseko zotseguka. Pokhala mosamala bwino, mwayi woti mungasokoneze ukhoza kuchepetsedwa.
Zida zamakina opanda waya , makamaka zomwe zimayambitsa 802.11g, zimakhala zatsopano. Monga ndi makina atsopano, yang'anani kuti zidzatenga nthawi kuti zinthu izi zidzakula.
Kuchita
Ma LAN opanda waya pogwiritsira ntchito 802.11b pothandizira pazomwe zimagwiritsidwa ntchito zakale zamtundu wa 11 Mbps, zofanana ndi za kale, Ethernet yachikhalidwe. Ma 802.11a ndi 802.11g WLAN amawathandiza 54 Mbps , pafupifupi theka la mgwirizano wa Fast Ethernet. Komanso, Wi-Fi ikuyenda kutali, kutanthauza kuti ntchito yayikuluyo idzagwetseratu makompyuta kutali kwambiri ndi malo olowera kapena malo ena othandizira. Pamene zipangizo zambiri zopanda zingwe zimagwiritsa ntchito WLAN kwambiri, ntchito ikuwononga kwambiri.
Zonsezi, kugwira ntchito kwa 802.11a ndi 802.11g ndikokwanira kugawidwa kwa intaneti kunyumba ndi kugawa mafayilo , koma kawirikawiri sikokwanira kusewera kwa LAN kunyumba.
Kuyenda kwakukulu kwa ma LAN opanda waya kumathandiza kuthetsa vutoli. Makompyuta a mafoni sayenera kumangirizidwa ndi chingwe cha Ethernet ndipo akhoza kuyenda mosasunthika mumtunda wa WLAN. Komabe, makompyuta ambiri apakhomo ndi mafano akuluakulu, ndipo ngakhale makompyuta amtundu wina nthawi zina amamangiriridwa ndi chingwe cha magetsi ndi chida cha mphamvu. Izi zimachepetsa mwayi wopita patsogolo kwa WLAN m'nyumba zambiri.
Chitetezo
Malingaliro, ma LAN opanda waya ali otetezeka pang'ono kuposa ma LAN wired, chifukwa zizindikiro zosayankhulira zopanda maulendo zimayenda mozungulira mlengalenga ndipo zimatha kulandidwa mosavuta. Pofuna kutsimikizira mfundo zawo, akatswiri ena amachititsa kuti azisamalira , zomwe zimaphatikizapo kuyendayenda kudera lokhalamo ndi Wi-Fi zipangizo zogwiritsa ntchito ma WIRAN opanda chitetezo.
Komabe, muyeso, zofooka za chitetezo chautetezi ndi zongopeka kuposa zofunikira. Ma WLAN amateteza deta yawo kupyolera muyezo Wired Equivalent Privacy (WEP) encryption standard, yomwe imapangitsa mauthenga opanda mafoni kukhala omasuka monga owongolera m'nyumba.
Palibe ma intaneti omwe ali otetezeka kwathunthu ndipo eni nyumba ayenera kufufuza nkhaniyi kuti atsimikizire kuti amadziwa komanso amakhala omasuka ndi zoopsa. Malingaliro ofunika otetezeka kwa eni nyumba samakonda kukhala okhudzana ndi ngati intaneti ikuwongolera kapena opanda waya koma m'malo motsimikizira:
- Pakhomo la Internet firewall ilikonzedwa bwino
- banja limadziwika ndi ngozi ya intaneti "spoof emails" ndi momwe mungawazindikire
- banja limadziwika ndi lingaliro la "spyware" ndi momwe mungapewere izo
- abysitters, oyang'anira nyumba, ndi alendo ena alibe mwayi wosafunafuna intaneti
