I-Computer Simple Network ye-Shared File
Lo mhlahlandlela kumanethiwekhi unqamula isihloko esihlokweni semiboniso ebonakalayo. Ikhasi ngalinye linomqondo owodwa oyinhloko noma isici senethiwekhi ye-wireless neyekhompyutha.
Lo mdwebo ubonisa uhlobo olulula kakhulu lwenethiwekhi yekhompyutha. Enenethiwekhi elula, amakhompyutha amabili (noma amanye amadivayisi asebenzayo) enza uxhumano oluqondile ngalunye futhi axhumane kunoma iyiphi ucingo noma ikhebula. Amanethiwekhi alula afana nalokhu asekhona amashumi eminyaka. Ukusetshenziswa okuvamile kulawa amanethiwekhi ukuhlanganyela kwefayela.

Inethiwekhi Yendawo Yendawo (i-LAN) nephrinta
Lo mdwebo ubonisa indawo ejwayelekile yendawo yenethiwekhi (LAN) . Amanethiwekhi wendawo yendawo avame ukufaka iqembu lamakhompiyutha asekhaya, esikoleni noma ingxenye yesakhiwo sehhovisi. Njengenethiwekhi elula, amakhompyutha kumafayela we-LAN wabelana namaphrinta. Amakhompiyutha ku-LAN eyodwa angakwazi ukwabelana ngokuxhumana namanye ama-LAN kanye ne-Inthanethi.

Ama-Network Wide Networks
Lo mdwebo ubonisa ukucushwa kwenethiwekhi yendawo enhle (WAN) ejoyina ama-LAN ezindaweni ezintathu zamadolobha amakhulu. Amanethiwekhi omhlaba wonke ahlanganisa indawo enkulu njengendawo edolobheni, izwe noma amazwe amaningi. I-WANs ivame ukuxhuma ama-LAN amaningi nakwamanye amanethiwekhi amancane wesilinganiso. Ama-WAN akhiwe ngezinkampani ezinkulu zokuxhumana zocingo nezinye izinkampani zisebenzisa imishini ekhethekile kakhulu engatholakali ezitolo zabathengi. I-intanethi yisibonelo se-WAN esijoyina amanethiwekhi wendawo kanye namadolobha amaningi kuwo wonke umhlaba.

Amanethiwekhi Wakhompyutha Wired
Lo mdwebo ubonisa izinhlobo ezimbalwa ezijwayelekile zokubambisana kwikhompyutha. Emakhaya amaningi, izintambo ezimbili ezisontekile ze- Ethernet zivame ukusetshenziswa ukuxhuma amakhompyutha. Ifoni noma i-cable cable imigqa ngokufanayo ixhuma ikhaya le-LAN kumhlinzeki wezinsizakalo ze-intanethi (ISP) . I-ISP, izikole ezinkulu namabhizinisi ngokuvamile bafaka imishini yabo yamakhompyutha kuma-racks (njengoba kubonisiwe), futhi basebenzisa ukuxuba kwezinhlobo ezahlukene zekhebula ukujoyina le mishini kuma-LAN naku-intanethi. Iningi le-intanethi isebenzisa ikhebula eliphezulu le- fiber optic ukuthumela amabanga amade omgwaqo ngaphansi komhlaba, kodwa iphini eliphosiwe kanye nekhebula le-coaxial lingasetshenziselwa imigqa eqashisiwe nakwezinye izindawo ezikude.

Izinethiwekhi zekhompyutha ezingenantambo
Lo mdwebo ubonisa izinhlobo eziningana ezivamile zamanethiwekhi wekhompyutha angenantambo. I-Wi-Fi iyinhlangano yobuchwepheshe obujwayelekile yokwakhiwa kwamanethiwekhi asekhaya angenantambo namanye ama-LAN. Amabhizinisi nemiphakathi futhi basebenzisa ubuchwepheshe obufanayo be-Wi-Fi ukusetha izindawo zokuhlala ezingenazintambo ezingenantambo . Okulandelayo, amanethiwekhi e- Bluetooth avumela ama-handhelds, amafoni omakhalekhukhwini namanye amadivaysi omsakazo ukuxhumana ngezigaba ezimfushane. Okokugcina, ubuchwepheshe benethiwekhi yeselula kubandakanya ukuxhaswa kwe- WiMax ne- LTE kokubili ukuxhumana kwezwi nokuxhumana kwedatha.

I-OSI Model of Computer Networks
Lo mdwebo ubonisa imodeli ye - Open Systems Interconnection (OSI) . I-OSI isetshenziswa kakhulu namuhla njengethuluzi lokufundisa. Isebenzisa amacebo ngenethiwekhi ibe yizingxenye eziyisikhombisa ekuthuthukisweni okunengqondo. Izendlalelo ezingezansi zithinta izibonakaliso zikagesi, izingxenye zedatha kanambambili, nokuhlelwa kwale datha kuwo wonke amanethiwekhi. Amazinga aphakeme ahlanganisa izicelo zenethiwekhi nezimpendulo, ukumelelwa kwedatha, nezinqubo zokuxhumana zenethiwekhi njengoba kubonwe endaweni yokubuka yomsebenzisi. I-model ye-OSI ekuqaleni yayikwakhelwe njengezakhiwo ezijwayelekile zokwakhiwa kwezinhlelo zenethiwekhi futhi empeleni, ubuchwepheshe abaningi bezinethiwekhi zenethiwekhi namuhla bubonisa ukuklama okuklanyelwe kwe-OSI.
