Iyini i-adaptha inethiwekhi? Kuyini adaptha LAN

Iyini i-adaptha inethiwekhi, lapho likhona futhi kusebenza kanjani? Nazi imibuzo esemqoka ukuthi ezothuthukiswa kulesi sihloko.

Kungani sasidingeka?

Adaptha - iyona imishini ukuthi igcina Isixhumanisi senethiwekhi namazinga ngokomzimba. It kungokwalabo okuphathelene nomngcele. It kuwuthinta ngokuqondile naphakathi ukudluliswa kwedatha. I-adaptha kuyinto ngempumelelo uyayixazulula inkinga onokwethenjelwa obmeta idatha kanambambili ku link zangaphandle. Ngenxa yokuthi ikhompyutha isilawuli, athwala umsebenzi walo ngaphansi kokulawula umshayeli efakwe kusistimu yokusebenza. Egibele njengoba adaptha inethiwekhi isokhethi umbadlana. Ishintsha amakhodi okufanayo asetshenziswa ikhompyutha, ku umfudlana amasignali ephezulu amandla, okuyinto idatha idluliselwa ngenethiwekhi. Ngakho-ke kubo ukubeka phambili imfuneko ukuhambisana ne uhlelo inethiwekhi yokusebenza ibhasi idatha ye-PC. Indlela ukufaka adaptha kwenethiwekhi ku umbadlana?

ukulungiswa

Kumele sizwisise ukuthi adaptha inethiwekhi, ungakwazi manje ukubukeza kanye nokulungiselela umsebenzi. Uma uhlangabezana PnP ejwayelekile, ukulungisa kuyinto othomathikhi. Kwelinye icala kubalulekile ngesandla ukusebenza ne uphazamisa isicelo umugqa futhi indawo yokufaka / okukhipha.

imisebenzi

Sesihlole ukuthi adaptha ezifana inethiwekhi, futhi kanjani it amisiwe, futhi manje ake sixoxe ngezinkinga ukuthi isixazululekile ekudluliselweni noma yokwamukela imiyalezo. Linani selilonkhe lebantfu labange eziyisishiyagalolunye:

1. Carry galvanically isehlane kusukela pair ezisontekile noma ikhebula coaxial. Ikakhulu asetshenziselwe le nhloso ishayela Transformers, nakuba kungenzeka futhi ukusetshenziswa optocouplers.
2. Transmission (reception) idatha. Bavela RAM ku-adaptha noma kwimemori computer ngokusebenzisa okufakwayo / okukhipha wesiteshi ukufinyelela ngqo.
3. Ukugcina kumthamo. Isetshenziselwa ukufanisa izinga ukudluliswa kwedatha kwe-adaptha noma kuwo ngendlela basuke ngobulili ngenethiwekhi. Futhi, ngesikhathi ngokucubungula ulwazi olugcinwe kwi-sesikhashana. It ivumela adaptha ukusebenza lonke iphakethe kolwazi. Futhi, sibonga adaptha kuyinto ukubambisana zedatha ezahlukene ingxenye LANs komunye nomunye.
4. Kumiswa iphakheji. idatha Network adaptha kufanele ihlukaniswe amabhlogo ahlukene ikumodi sokudlulisa (noma Bazophuma reception), khona-ke ukuhlela kwabo njengoba isimo osayizi abathile. Kuzobakhuthaza sakhiwa Amasimu inkonzo eziningana, lapho ikheli computer uya khona, futhi checksum ifreyimu lapho idivayisi uthola isiphetho ngabantu ukuthi ulwazi zilethwe ilungile.
5. Ukufinyelela isiteshi zokuxhumana. Futhi ngo "yomthetho" yakhe iqoqo imithetho ezingasiza uthola ithuba ukusebenza konemimoya yokudlulisela. Ngaphezu kwalokho, i-adaptha kuthola izingxabano futhi uqaphe isimo inethiwekhi.
6. Ukukhomba le iphakethe ukuthi kutholwa. Kungaba izonqunywa ukushintsha simonhlalo, ithungwe e Prom noma egcinwe kwirejista ekhethekile.
7. Guqula ikhodi ukufana serial ukuthumela idatha, futhi ubenza emuva lapho ukuguqulwa wabo reception. Of lokhu kukhona ngaphandle amancane. Lapho esebenzayo ukuthumela idatha imodi, ulwazi yokuxhumana siteshi adlulisiwe ikhodi ezilandelanayo.
8. Ukufaka ikhodi / emagama idatha. Kulesigaba kwakhiwa yezinzwa ezisetshenziswa ukumela inani. Ezimweni eziningi, i-Manchester wekhodi. Le ndlela akudingeki ukuba adlulisele isiginali ukuvumelanisa ukuqaphela yibo futhi amaqanda. Kulokhu, ushintsho polarity.
9. Ukuthola noma yokudlulisela idatha pulses.

Futhi inethiwekhi adapters lapho esebenza isofthiwe ezidingekayo ingaze nesibambo nephutha ukuthi kwenzeka ngenxa Kungasebenti kahle kwaletinye imishini, ukushayisana, kumbe impambaniso yegetsi.

ikheli isizinda

Futhi kubizwa ngokomzimba. Ingxenye adapters inethiwekhi angasebenzisa inkumbulo sekhompyutha njengoba sesikhashana ukugcina amaphakethe idatha angenayo naphumayo. Base ikheli kuleli cala ebizwa inombolo ye-hexadesimali, okhombisa lapho ulwazi.

Ukwahlukanisa izindlela ukufinyelela imizuzu kanye imvelo

Ubuchwepheshe elisetshenziswayo lenethiwekhi izinhlobo ezintathu oyinhloko adaptha:

1. I-Ethernet.
2. FDDI.
3. Ring Token.

Ngokuvamile, umfuziselo othile isebenza kuphela ngokwa inethiwekhi ubuchwepheshe. Kodwa ngesikhathi esifanayo bakwazi ukusekela, njengoba umthetho, eziningana ezahlukene yokudlulisela abezindaba. Ngokwesibonelo, i-Ethernet isebenza:

1. Fiber-optic ikhebula.
2. Unshielded pair elisontiwe.
3. ikhebula Coaxial.

Uma idivayisi usebenza nge imvelo ngawo ekuqaleni yakhelwe, le converters transceivers esetshenziswa. Futhi inethiwekhi adapters zihlukaniswa yangaphakathi idatha ibhasi:

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

On lokho imingcele the adapters inethiwekhi kungenziwa labizwa?

Ngaphezu kwalezi, ingaphinda isetshenziswe yilezi:

1. Uhlobo Bus.
2. usayizi Buffer iphakheji.
3. ukudluliswa izinga.
4. Oluvumelana nge microprocessors ezahlukene.
5. Ukusebenza amathayi.
6. Ngokusho khona / ukungabikho ukusetshenziswa ungeno ngqo esikhaleni.
7. isixhumi design.
8. Ekhuluma okukhipha izimbobo / okokufaka futhi ziphazamise izicelo.

Ukuqaliswa ngokomzimba

Asithathe njengesibonelo, cabanga adaptha inethiwekhi-Windows 7. kakhulu ingxenye zingafakwa ku-motherboard. Kodwa lapha TP-Link Iseluleki Sokufaka Iphrinta Yenethiwekhi isuselwe ngaphesheya chassis. Lena akuyona okungenani ngenxa ukusebenza yayo (ikhono ukuxhuma amakhompuyutha kanye ukwakha inethiwekhi ye-Wi-Fi, okungukuthi, yena ikhonza njengombonisi router, kanye umzila). Isici yokugcina ivumela adaptha ukudala ngisho encane inethiwekhi yendawo, okuletha ndawonye wonke amadivayisi nge-interface ezidingekayo eseduze. Ungase futhi uthole i-USB AC. Kuvamise abantu ukunikela mobile inethiwekhi opharetha. USB-adaptha ye-AC kuleli cala libukeka drive flash, bese uxhuma ngendlela efanayo. Ukuze idatha ukudluliswa liyasetshenziswa 2G noma 3G Inthanethi. ukubonakaliswa Lapha zomphakathi phambi kwethu ingase iveze Iseluleki Sokufaka Iphrinta Yenethiwekhi-Windows 7. By endleleni, nokuthi kudivayisi luyasetshenziswa encwadini? Uma sikhuluma Asus AC, kumelwe abe khona kuwo wonke amadivayisi. Kuyefana nasendleleni nezinye laptops. Iqiniso ukuthi zenzelwe ukusetshenziswa ezindaweni ezihlukahlukene, okubalwa kuzo umakhalekhukhwini, uma une ukusebenza nawo wonke umuntu.

isiphetho

Ngakho, sathola ukuthi adaptha ezifana inethiwekhi, yiziphi izinhlobo kukhona futhi kanjani they ezisetshenziswa umkhuba. thina nabo baye basibona isibonelo ngokwakha inethiwekhi yendawo nabo. Ekuphetheni, kufanele bathi zingatholakala hhayi kuphela kumakhompyutha ekhaya noma laptops, kodwa futhi kwiseva yomhlinzeki, okunikeza Ukufinyelela i-Inthanethi kubasebenzisi zabo. lapha kuphela isetshenziswa njengoba esangweni zesikhashana.
