Izinhlobo Computer Networks

Kuyaziwa ukuthi omunye impumelelo enkulu kakhulu kwekhulu elidlule kwakungu ekudalweni kwesintu kanye ukuthuthukiswa ngokushesha ulwazi nobuchwepheshe - ubuchwepheshe, usebenzisa amakhompyutha kanye nezinhlobo ezahlukene ikhompyutha amanethiwekhi, esitolo, inqubo, ukuguqula futhi uthumele esiningi ulwazi. Kuyaphawuleka ukuthi gxuma enjalo okusheshayo kolwazi abantu isibe kungenzeka kuphela ngemuva amanethiwekhi zokuxhumana computer ziye zadalwa.

Zonke izinhlobo zokuxhumana computer iqoqo amakhompyutha basakaza phezu endaweni ethile futhi oxhumene by iziteshi ayisipesheli, ukuvumela ukudlulisa idatha. Namuhla amanethiwekhi computer ezisetshenziswa kabanzi, izinhlobo ezahlukene zokuxhumana computer ezisebenza emhlabeni wonke futhi nihlanganyele. ukuqonda Wanamuhla izici amanethiwekhi, kuye kwaholela Ukwahlukaniswa isimiso indawo. Ngokusho lokhu ngezigaba lifaka phakathi izinhlobo ezifana amanethiwekhi computer:

Global Area Network (GAN) - inethiwekhi global zekhompyutha inethiwekhi itholakala ezindaweni ezihlukahlukene zezwe.

Wide Area Network (WAN) - amanethiwekhi emikhulu ukuthi sihlanganise amanethiwekhi computer ezingeni amazwekazi kanye namazwe;

Metropolitan Area Network (MAN) - eside ibanga amanethiwekhi zekhompyutha amanethiwekhi ngaphakathi izifunda kanye nezinye amayunithi nezokuphatha;

Local Area Network (LAN) - LAN, lokusho ukuhlanganiswa lwamakhompyutha akhiwe kude esifushane - ngokwesibonelo, ngaphakathi esakhiweni efanayo.

WAN futhi MAN kukhona amanethiwekhi lesifunda. Kuyaphawuleka ukuthi kuze kube yimanje, esigabeni sika-amanethiwekhi ikhompyutha WAN futhi UMUNTU okunemibandela kakhulu, njengoba manje cishe njalo inethiwekhi lesifunda kufakwe kunoma iyiphi inethiwekhi global.

Izinhlangano eziningi ukuthi unesithakazelo ukuhlinzeka ezingeni lelisetulu Ukuvikelwa Imininingwane ngokumelene nokungena kusukela ngaphandle (isibonelo, ibutho lezempi, amabhange, njll), ukudala amanethiwekhi zabo, eyaziwa ngokuthi yenkampani. Ngo inethiwekhi yenkampani ingase ihlanganise amashumi ezinkulungwane kumakhompyutha zitholakala endaweni amabanga amade uma liya komunye nomunye, isibonelo, emazweni ehlukene.

Okuvame kakhulu emhlabeni anda kukhona amanethiwekhi kukhompyutha yakho yendawo.

Isici esiyinhloko ukuthi kungenzeka amanethiwekhi wendawo endaweni ukuxhuma amakhompyutha ikhebula ngaphandle asebenzise iziteshi ukuthumela idatha, zisebenzisa ebanzi endaweni amanethiwekhi (sezingcingo, fibre optic ikhebula, Umsakazo nokunye.). Kusukela amakhompyutha zitholakala eduze komunye nomunye, ukwakha inethiwekhi ukuxhuma okwanele ikhebula yabo futhi ulungise ngokufanele. Senethiwekhi kwama-computer inethiwekhi ikhompyutha IPLs eyenza umnikazi yayo eziningi eziwusizo.

Izinhlobo amanethiwekhi kukhompyutha yakho yendawo ngokuvamile ukwabelana yomphindwa - indlela yokuxhuma amakhompyutha komunye nomunye. I yomphindwa kuyinto isici esibalulekile amanethiwekhi wendawo, njengoba inqunywa indlela izibalo kwakwakhe egqamileyo eyethulwa ukusebenza kanye nokusebenza nokwethenjelwa.

Inzuzo enkulu inethiwekhi okwenzile ngokuvumelana yomphindwa "lwenkanyezi" - komunye umthombo emaphakathi ixhunywe wonke amanye amakhompyutha akwinethiwekhi.

Kube inethiwekhi, kwakheka ngokuvumelana yomphindwa we "indandatho" - wonke amakhompyutha ukuxhumana nomunye uchungechunge futhi ekugcineni yakha ofana indandatho.

Uhlobo wesithathu yomphindwa, okuyinto zidalwe amanethiwekhi computer wendawo, a yomphindwa ibhasi - wonke amakhompyutha uxhumeke ikhebula olulodwa - idatha ibhasi.

amanethiwekhi Computer, ukuthi kusebenza kanjani, yezifiso, futhi izingxenye hardware njalo ngcono futhi.
