Yintoni na iadaptha? Yintoni a kagesi LAN

Yintoni iadaptha womnatha, apho sibekwe khona kwaye isebenza njani? Nantsi ke imibuzo ephambili iza kuphuhliswa kweli nqaku.

Kutheni lento kufuneka?

Adaptha - na izixhobo igcine unxibelelwano womnatha kunye namanqanaba emzimbeni. Lingcwaba lomfo peripherals. It isebenzisana ngqo ugqithiso lwedata esiphakathi. Zombini i ngempumelelo elisombulula ingxaki ngedatha ethembekileyo obmeta yokubini kwi links yangaphandle. Ngokuba nguye computer isilawuli, athwala umsebenzi walo phantsi kolawulo lomqhubi efakiweyo kwinkqubo yokusebenza. Onyuswe njenge iadaptha kwi kwisokethi motherboard. Itshintsha Iikhowudi parallel ezisetyenziswa ngekhompyutha, zibe lwemiqondiso eziphakamileyo ngamandla, nto leyo data usasazwa ugqithiselwa ngapha komsebenzi womnatha. Ngoko ke kubo ukubeka phambili imfuneko wokuhambelana network zokusebenza kunye data ibhasi ye-PC. Indlela ukufakela iadaptha kwi motherboard?

ukulungiswa

Kufuneka siqonde ukuba yintoni iadaptha, ngoku kwakhona ukulungiselela umsebenzi. Ukuba ihlangabezana umgangatho PNP, olo hlengahlengiso kuyakuqhubeka. Kwelinye ityala kuyimfuneko ukusebenza ngesandla kunye isicelo sophazamiso umgca kunye indawo igalelo / imveliso.

imisebenzi

Siye sahlolisisa ukuba onjalo iadaptha, kwaye ilungiswe njani, kwaye ngoku makhe sithethe ngeengxaki ukuba isonjululwe ekudluliseni okanye ulwamkelo lwemiyalezo. Zizonke alithoba:

1. Phumeza galvanically zodwa ukusuka isibini ephinyaphinyelayo okanye intambo yafakwa. ezisetyenziselwa ikakhulu ngenxa yale njongo abaguquli ukubetha, nangona kunokwenzeka kunye nokusetyenziswa optocouplers.
2. Transmission (reception) lwe data. Bavela RAM ukuya zombini okanye kwimemori ye computer nge igalelo / imveliso channel kunye ufikelelo ngqo.
3. Komthamo. Oku kusetyenziswa ukufanisa izinga transfer idatha zombini okanye kuyo kunye nendlela kokuba idluliselwe ngapha komsebenzi womnatha. Kwakhona, ngexesha lokulungiswa ulwazi igcinwa kwi buffer. Ivumela zombini ukusebenza yonke impahla kolwazi. Kwakhona, ngenxa zombini i amazinga data kudityaniswe LANs yecandelo ezahlukeneyo omnye komnye.
4. Formation of iphakheji. data iadaptha Network kufuneka yahlulwe iibhloko ezahlukeneyo ikwimo ayidlulisele (okanye ukuba abahamba reception), ngoko ukuba wozibeka njengesakhelo elimlinganiselo ethile. Kuya yenziwe kwamabala iinkonzo eziliqela, apho idilesi ye computer kuyo, kwaye checksum yesakhelo apho ifowuni ifumana kwisigqibo malunga nokuba ingcaciso kusiwa ichanekile.
5. Ukufikelela a ijelo lonxibelelwano. Kwakhona ku "kolawulo 'bakhe iseti yemithetho kukunceda ufumane ithuba lokuba ukusebenza transmission esiphakathi. Ukongeza, zombini ibhaqa lweemfazwe esweni nesimo senethiwekhi.
6. Ukuchongwa nedilesi zepakethe ukuba yamkelwe. Oko imiselwe itshintshela sentlalo, athungwe e isithembiso okanye kugcinwe irejista ekhethekileyo.
7. Guqula ikhowudi umfuziselo kokwaziswa serial, kwaye ubenza umva xa ulwamkelo lwabo ukuguqulwa. Kule kukho ngaphandle encinane. Xa imo ugqithiso lwedata esebenzayo, ulwazi ijelo lonxibelelwano ufuduswa ikhowudi yokulandelelana.
8. Usebenziso ngekhowudi / kokuhlaziya lwe data. Kweli nqanaba imiqondiso yombane kwakheka asetyenziswe ukumela ulwazi. Kwiimeko ezininzi, a Manchester encoding. Lendlela akuyomfuneko ukuba angadlulisela uphawu ungqamaniso ukuqaphela abo kunye amaqanda. Kulo mzekelo, utshintsho wokwephuka.
9. Ukwamkela okanye kudluliswe pulses data.

Kunye ezisebenza ngokubakho womnatha xa usebenza isoftware eyimfuneko unganokuqonda nokusingatha impazamo oko kwenzeka ngenxa yokusebenza abaziintsizana izixhobo, yokungqubana, okanye ukuphazamiseka yombane.

idilesi base

Kwakhona ebizwa emzimbeni. Inxalenye amaqhoshana womnatha angasebenzisa memory yekhompyutha njenge buffer ukugcina iipakethi data ezingenayo neziphumayo. idilesi Base kule meko ibizwa ngokuba njengenani elinekona ezintandathu, nto leyo ibonisa apho ulwazi.

Ukuhlelwa iindlela lokufikelela imizuzu kunye nokusingqongileyo

Ithekhnoloji womnatha esetyenziswa iintlobo ezintathu ezingundoqo kagesi:

1. Ethernet.
2. FDDI.
3. Ring umqondiso.

Ngokuqhelekileyo, indlela ethile isebenza kuphela ngokwayo technology womnatha. Kodwa kwangaxeshanye bakwazi ukuxhasa, njengoko umthetho, ezininzi ezahlukeneyo zothumelo eendaba. Umzekelo, Ethernet esebenza:

1. Ifayibha-optic cable.
2. pair Unshielded, ephothiweyo.
3. intambo yafakwa.

Xa ifowuni ukuba ukusebenza kunye nokusingqongileyo apho kwathiwa yenzelwe ekuqaleni, le converters kunye transceiver ezisetyenzisiweyo. Kunye ezisebenza ngokubakho womnatha ahluka yi-data ibhasi yangaphakathi:

1. PCI.
2. EISA.
3. ISA.
4. MCA.

Kuphantsi kweziphi parameters le amaqhoshana womnatha na zihlelwe?

Ukongeza kwezi, ukuze usetyenziswe zezi:

1. Uhlobo Bus.
2. Ubungakanani ephakathi ukuze iphakheji.
3. rate transfer.
4. Ayahambisana microprocessors ezahlukeneyo.
5. amasondo Performance.
6. Ngokutsho ubukho / ukungabikho ukusetyenziswa ufikelelo ngqo kwimemori.
7. design isinxibelelanisi.
8. Ethetha amazibuko output / igalelo kwaye ziphazamise izicelo.

Ukuqaliswa ngokomzimba

Mandithathe likaThixo njengomzekelo, cinga ukuba iadaptha for Windows 7. Xa becala ukuba zibekwe phezu motherboard. Kodwa apha TP-Link network iadaptha lithathwe ngaphaya kwisisu semoto. Oku akuthethi noko ngenxa ukusebenza kwayo (ukukwazi ukudibanisa iikhompyutha ezininzi nokudala uthungelwano Wi-Fi, oko kukuthi, yena naye ukhonza zendlela, kwaye umzila). Olona phawu yokugqibela ivumela zombini ukwenza noba ariya yobulali yomsebenzi womnatha encinane, nto leyo ezisa ndawonye zonke izixhobo kunye ujongano eziyimfuneko apha. Ungafumana kwakhona & nbsp USB-AC-adaptha. Oku ngesiqhelo abantu zinika inethiwekhi yeselula. USB-AC adaptor kule meko ikhangeleka ngathi flash drive, uze uqhagamshele kuyo ngendlela efanayo. Kuba data transmission lendlele ikwasetyenziswa 2G okanye 3G Internet. obubonakala Apha esidlangalaleni phambi kwethu engase iadaptha for Windows 7. endleleni, nokuba ifowuni iphunyeziwe yokubhala? Ukuba sithethe Asus AC iadaptha, kufuneka abekho ngamayelenqe. Kukwasebenza kwanjalo kwabanye laptops. Inyaniso ukuba yenzelwe ukuba isetyenziswe kwiindawo ezahlukeneyo, kuquka mobile, xa kufuneka asebenze nawo wonke.

isiphelo

Ngoko ke, siye safumanisa ukuba onjalo iadaptha, yintoni iindidi kukho nendlela ukuba zizalisekiswe kwi practice. siye sibone umzekelo ekudaleni ariya yobulali yomsebenzi womnatha nabo. Xa ndiqukumbela, sifanele sithi ukuba inokufumaneka kuphela kwiikhompyutha ekhaya okanye laptops, kodwa kwiseva yababoneleli, nezinika ukufikelela intanethi ukuya kubasebenzisi zabo. Kuphela apha isetyenziswa njenge ndlela yesango lenguqu.
