Types of Computer Networks

Yinto eyaziwayo ukuba omnye ezenziweyo nezibaluleke kakhulu kwinkulungwane yokugqibela yaba ekudalweni uluntu kunye nophuhliso olukhawulezayo kubuchwepheshe zolwazi - ubugcisa, ukusebenzisa iikhompyutha kunye neendidi ezahlukeneyo lothungelwano computer, ivenkile, inkqubo, ziguqule kunye nokudlulisela ulwazi oluninzi. Kubalulekile ukuphawula ukuba utsibe ngokukhawuleza ezifana kolwazi uluntu iye kunokwenzeka kuphela emva kokuba ziye wadala uthungelwano zonxibelelwano computer.

Zonke iintlobo zothungelwano eekhompyutha ingqokelela iikhompyutha kuka kwindawo ethile kwaye amaqhina oqhagamshelwano yi imijelo ezizodwa, elikuvumela ukuba ukudlulisela data. Namhlanje networks computer zisetyenziswa kakhulu, iintlobo ezahlukeneyo lothungelwano computer yokusebenza kwihlabathi jikelele kwaye banxibelelane nabanye. ukuqonda yakutshanje iimpawu zothungelwano, kukhokelele ukuhlelwa umgaqo indawo. Ngokwale yokuhlela iquka iintlobo ezifana lothungelwano computer:

Global Area Network (Gan) - uthungelwano lwehlabathi iikhompyutha kunye uthungelwano ibekwe kwindawo ezahlukeneyo zehlabathi.

Area Network Wide (WAN) - networks ezinkulu-isikali ezidibanisa uthungelwano khompyutha kwinqanaba amazwekazi namazwe;

Area Network Metropolitan (MAN) - networks umgama elide iikhompyutha kunye nothungelwano ngaphakathi kwiingingqi kunye nezinye iiyunithi zolawulo;

Area Network Local (LAN) - LAN, okuthetha ukudityaniswa kweekhompyutha akhiwe kumgama omfutshane kakhulu - umzekelo, ngaphakathi isakhiwo esifanayo.

WAN kunye omntu iinethiwekhi zengingqi. Kubalulekile ukuphawula ukuba umhla, iyantlukwano zothungelwano computer kwi-WAN kunye MAN lunemiqathango kakhulu, njengoko ngoku phantse zonke womnatha lwengingqi ifakiwe na womnatha lwehlabathi.

Imibutho emininzi banomdla ngokubonelela inqanaba eliphezulu lokukhuselwa ulwazi nxamnye nokungena ezivela ngaphandle (umzekelo, emkhosini, iibhanki, njalo-njalo), ukudala uthungelwano zabo, eyaziwa ngokuba loshishino. Inethiwekhi yequmrhu ingaquka amashumi amawaka iikhompyutha ukuba yenziwa sikude kakhulu enye kwenye, umzekelo, kumazwe awahlukeneyo.

Avamise kakhulu ehlabathini ngamanani kukho uthungelwano computer wendawo.

Olona phawu engundoqo amathuba ndawo uthungelwano local ukudibanisa iikhompyutha intambo ngaphandle kokubhenela kwiindlela ukuba ugqithiso lwedata, sebenzisa ebanzi indawo networks (kwenethiwekhi yefowuni, ifayibha optic, usasazo kunomathotholo njalo njalo.). Ekubeni computer ibekwe kufuphi enye kwenye, ukuba udale uthungelwano ukudibanisa ngokwaneleyo of cable ukuncama ngokufanelekileyo. Olungagcinwanga lweekhompyutha kuthungelwano computer IPLs inika umnini wayo ezininzi iingenelo.

Types of network computer wendawo ngokuqhelekileyo yabelana yethopholoji efanayo - indlela yokuqhagamshelana iikhompyutha omnye komnye. Le ithopholoji yi luphawu ebalulekileyo iiwebhsayithi ekuhlaleni, ekubeni yona umiselwa indlela amanani compound ephambili thaca yokusebenza kunye nokusebenza nokuthembeka.

Uncedo enkulu womnatha bawugcinile ngokungqinelana ithopholoji of "inkwenkwezi" - to eyodwa mthombo elidityaniswe zonke ezinye iikhompyutha kwi-network.

Kukho inethiwekhi, kwakheka ngenxa ithopholoji le "ring" - zonke iikhompyutha banxibelelane nabanye ngayo series ekugqibeleni benza into efana ngomsesane.

A Uhlobo lwesithathu ithopholoji, ezidaliweyo yi uthungelwano computer wendawo, ibhasi yethopholoji efanayo - zonke iikhompyutha uqhagamshele intambo single - bus data.

networks computer, ukuba zisebenza njani, iiprotokoli, kunye namacandelo iintsimbi rhoqo ukuba iphuculwe kwaye ziphuhlisiwe.
