I-NIC ifinyelele kwikhadi lesikhangiso senethiwekhi . I- adapter ye-hardware yenethiwekhi ngendlela yekhadi lokungeza elihambisana nesandiso sokwandisa ebhokisini lomama wekhompuyutha. Amakhomphyutha amaningi awakhile kuwo (uma kunjalo ayingxenye yebhodi lesifunda) kodwa ungongeza futhi i-NIC yakho yokwandisa ukusebenza kwesistimu.
I-NIC yiyona enikeza isikhombimsebenzisi se- hardware phakathi kwekhompyutha nenethiwekhi. Lokhu kuyiqiniso ukuthi inethiwekhi ifakwe wired noma engenantambo kusukela i-NIC ingasetshenziselwa amanethiwekhi e- Ethernet kanye ne- Wi-Fi , kanye nokuthi ideskithophu noma i-laptop.
"Amakhadi enethiwekhi" axhuma ngaphezu kwe- USB akuwona amakhadi kodwa kunalokho amadivaysi ejwayelekile e-USB anika amandla uxhumano lwenethiwekhi ngokusebenzisa i- USB port . Lezi zibizwa ngokuthi i- adapters yenethiwekhi .
Qaphela: i- NIC iphinde imele i-Network Information Center. Isibonelo, inhlangano i-InterNIC i-NIC enikeza ulwazi emphakathini jikelele kumagama wesizinda se-intanethi.
I-NIC Yenzani?
Kulula, ikhadi lesikhangiso senethiwekhi yenza idivaysi ixhumane namanye amadivaysi. Lokhu kuyiqiniso ukuthi ngabe amadivaysi axhunyiwe kwinethiwekhi eyinhloko (njengokufana nemodi yesikhungo ) noma noma ngabe ahlangene ndawonye, ngokuqondile kusuka kudivayisi eyodwa kuya komunye (ie mode-ad hoc ).
Kodwa-ke, i-NIC ayisoloko iyodwa into edingekayo ukusebenzisana namanye amadivaysi. Isibonelo, uma idivaysi ingxenyeni yenethiwekhi enkulu futhi ufuna ukuba ibe ne-intanethi, njengekhaya noma ebhizinisini, kudingeka futhi router . Ngakho-ke, idivayisi isebenzisa ikhadi lesikhangiso senethiwekhi ukuxhuma ku-router, exhunyiwe ku-intanethi.
I-NIC Incazelo Yomzimba
Amakhadi enethiwekhi afika ngezindlela ezahlukene kodwa ama-main ayenziwe futhi anamasondo.
Ama-NIC angenantambo adinga ukusebenzisa ubuchwepheshe obungenawaya ukufinyelela kwinethiwekhi, ngakho-ke bane-antenna eyodwa noma ngaphezulu ephuma ekhadini. Ungabona isibonelo salokhu nge-TP-Link PCI Express Adapter.
Ama-NIC aphephile asebenzisa kuphela i- RJ45 port ngoba anekhebula le-Ethernet elihlanganisiwe ekugcineni. Lokhu kwenza kube lula kakhulu kunamakhadi enethiwekhi angenantambo. I-Adapter Network Network ye-TP-Link Gigabit Ethernet isibonelo esisodwa.
Kungakhathaliseki ukuthi kusetshenziswe yini, i-NIC ihamba phambili ngemuva kwekhompyutha eduze kwamanye ama-plugs, afana nokuqapha. Uma i-NIC ixhunyiwe kwi-laptop, kungenzeka ukuthi ifakwe eceleni.
Ukushesha Kanjani Amakhadi Enethiwekhi?
Wonke ama-NIC afaka isilinganiselo sejubane, njenge-11 Mbps, 54 Mbps noma 100 Mbps, okuphakamisa ukusebenza jikelele kweyunithi. Ungathola lolu lwazi ku-Windows ngokuchofoza ngakwesokudla uxhumano lwenethiwekhi kusuka kuNethiwekhi noKwabelana Ngendawo> Shintsha ingxenye yezilungiselelo ze-adapter yePaneli Yokulawula .
Kubalulekile ukukhumbula ukuthi ijubane le-NIC alinqumi ukujula kokuxhumeka kwe-intanethi. Lokhu kungenxa yezizathu ezifana ne- bandwidth etholakalayo nejubane okhokhayo.
Isibonelo, uma ukhokha kuphela isivinini sokulanda esingu-20 Mbps, usebenzisa i-NIC eyi-100 Mbps ngeke yande ngesivinini sakho ku-100 Mbps, noma ngisho nanoma yini engaphezu kuka-20 Mbps. Kodwa-ke, uma ukhokha ama-Mbps angu-20 kodwa i-NIC yakho isekela kuphela ama-Mb Mb 11 kuphela, uzothola ngesivinini esincane sokulanda kusukela i-hardware efakwe kuphela isebenza ngokushesha njengoba ilinganisiwe ukusebenza.
Ngamanye amazwi, ijubane lenethiwekhi, uma nje lezi zici ezimbili zicatshangelwa, kunqunywa ukuthi kancane kancane.
Omunye umdlali omkhulu ekuvinjeni kwenethiwekhi yi-bandwidth. Uma ngabe uthola ama-Mb Mbhidi angu-100 futhi ikhadi lakho lisekela, kodwa une amakhompyutha amathathu enethiwekhi ayilanda ngesikhathi esisodwa, ukuthi amamitha ayi-100 azohlukaniswa emithathu, ezosiza kuphela iklayenti ngalinye elizungeze 33 Mbps.
Lapho Ukuthenga Amakhadi Enethiwekhi
Kunezindawo eziningi lapho ungathenga khona ama-NIC, kokubili ezitolo naseku-intanethi.
Abanye abathengisi be-intanethi bafaka i-Amazon ne-Newegg, kodwa izitolo zomzimba ezifana ne-Walmart zithengisa amakhadi enethiwekhi.
Indlela Yokuthola Amashayeli Amakhadi Enethiwekhi
Wonke amadivayisi we-hardware adinga amashayeli wedivayisi ukuze asebenze nesofthiwe kukhompyutha. Uma ikhadi lakho lenethiwekhi lingasebenzi, kungenzeka ukuthi umshayeli ulahlekile, wonakalisiwe noma awuphelelwe yisikhathi.
Ukubuyekeza abashayeli bamakhadi enethiwekhi kungaba yinto ekhohlisayo ngoba ngokuvamile udinga i-intanethi ukuze ulande umshayeli, kodwa ukukhishwa komshayeli kukuvimbela ukuthi ungangeni kwi-intanethi! Kulezi zimo, kufanele ulande umshayeli wenethiwekhi kwikhompyutha esebenza bese uyithumela ohlelweni lwenkinga nge- flash drive noma i-CD.
Indlela elula yokwenza lokhu ukusebenzisa ithuluzi lokuvuselela umshayeli elingakwazi ukuskena izibuyekezo ngisho nalapho ikhompyutha ingaxhunyiwe ku-intanethi. Qalisa uhlelo ku-PC oludinga umshayeli bese ulondoloza ulwazi efayeleni. Vula ifayela kuhlelo olufanayo lokuvuselela umshayeli kwikhompyutha esebenzayo, landa abashayeli bese ubathumela ekompyini engekho ukusebenza ukuze ubuyekeze abashayeli lapho .
