Global kombiyuta Network

Computer Network - haasi chinhu asi pamwe makombiyuta akawanda pamwe chete, achivabvumira kuchinjana mashoko. Global rezvebonde kudaidzwa kana vafukidza vanoshandisa kubva pasi pose. Cherechedza kuti okutanga network kombiyuta kwevanhuwo zvavo akazviratidza muUnited States. Asi vanhu vashoma vanoziva kuti zvikuru musimboti ruzivo urwu yakatanga kushandiswa muna USSR, uye nokuda kwaizvozvi kare yokutanga chombo kuzvidzivirira hurongwa akasikwa.

Nhasi, kune kumbonyanya yakafara Network kupatsanura. Maererano spatial riparadzirwe anokudzwa munyika yose, kwematunhu uye nemakanzuru kombiyuta network. Global kombiyuta Network network dziri munharaunda ehurumende kana akawanda anoti Somuenzaniso, munyika yose Internet. LANs akafukidza imwe nzvimbo kusvikira zvakawanda makumi ezviuru mativi metres, uye romunharaunda - iri samambure, izvo dziri munharaunda kana guta.

Zvisinei, vaviri kiyi izwi iri kupatsanura pakati network - ndiko: Wan uye Lan.

WideAreaNetwork (Wan) - yose kombiyuta network, kufukidza nzvimbo huru, izvo zvinosanganisira munzvimbo network uye mamwe telecommunication namano uye network.

LocalAreaNetwork (Lan) - Ethernet, izvo nevachena kwezvivako pamberi ayo kusunungurwa nomusi basa rubatsiro. The chaizvo chete rokuti «Lan» akakwanisa kutsanangura uye duku hofisi network, uye hombe chirimwa Network kuti ndokwenguva nzvimbo anoverengeka zana maeka.

Mukuru munyika yose rezvebonde iri Internet. Inopa dzakasiyana kubatanidza makombiyuta kure, uye mukuru kushandisa ruzivo pfuma uye kuparadzirwa mabasa.

Pakutanga, munyika yose network kombiyuta tichiita kugadzirisa chinetso kuwana akawanda kure zviteshi uye makombiyuta pamakombiyuta simba, rinonzi nehondo-s. kwokubatana aya akaita Via unswitched kana kushandisa migero runhare Network kana Via vakazvitsaurira Satellite Data network Somuenzaniso, kushanda X.25 Protocol.

Kubatanidza flow dzakadaro kushandisa Modem riri muchimhanya kushandiswa foni zvirongwa, COMIT mhando, PROCOM, BITCOM, MITEZ nevamwe. Managed Os MS-Dos, vanofanira kutsinhanisa ruzivo pamwe kombiyuta kuti zvakanzi zvakabatana.

The chaizvo chete kuvaka yose samambure tsanangura haisi zvakaoma. The pose rezvebonde ine masero kuti ndiyo network vemo. In kwezana LANs ine network zviduku uye munhu makombiyuta. Herino multi-sandara akanyatsorongwa uye inoita kuvakwa pemambure. Uyezve, mudziyo mumwe nomumwe pamusoro pemambure anofanira kuva yayo IP-kero, kana nemamwe identifier.

Mazuvano, zvishoma uye zvisinganyanyi kushandiswa makombiyuta chete riri munyika yose kombiyuta Network. Zvikurukuru, ndiko - musha hrs. Kazhinji kacho, vaya subscribers pomumbure makombiyuta, izvo wakazopinzwa omunzvimbo nharaunda network, saka, vanachiremba vakawanda kufunga nzira kuti ape nani kudyidzana anoverengeka munzvimbo network. Zvakafanira iyi nyaya kugovera kumaruwa kombiyuta ine chokuita chero kombiyuta mukati yomunharaunda rezvebonde ari kure, kana vakutarisire. Yokupedzisira nzira rinoshanda zvikuru sezvo uwandu musha uye makombiyuta.

Zvino shandisa nokuchinja nzvimbo dziri X.25 network kushandiswa mano Telenet-kugadzira makambani, Ericsson, Siemens sezvo nomumbure zvokushandisa, Alcatel uye saka, zvakanaka, kuti TCP / IP network vanoshandisa routers uye Cisco Decnis yemakambani. Zvisinei, unyanzvi hwokugadzira zvinhu haisi akamira, uye zvingangodaro kuti mune ramangwana tichaona chinotokurudzira zvokufambisa sangano munyika network, iyo zvino ine guru kukanganisa upenyu anenge munhu wose.
