Global network

Mune kombiyuta yekombiyuta, kuita kuti kuwirirana kwezvikamu zvehutano hwehutano, maitiro anokosha anoshandiswa, ayo anonzi mitemo. Ivo hardware uye software. Zvigadzirwa zvemichina (interfaces) zvinotsigira maitiro pahutano hwepanyama, uye pazinga re data vanoshanda nehuwandu hwekusimbisa software.

Nzvimbo dzepasi uye yenyika dzakasarudzwa dzinoshandiswa nezvirevo zvavanoshandisa. Mune hutano hwemunharaunda, makombiyuta anoshandisa mararamiro anowirirana kune vose vanobatanidza mitambo, uye kubatanidza makombiyuta eimba, zvivako, pasi.

Purogiramu yepasi rese inowanzovhara nzvimbo huru. Vanobatanidza zvose zvemakombiyuta nemakombiro emunharaunda vachishandisa mitemo yakasiyana.

Mabasa evanhu vakabudirira mumamiriro emazuva ano hazvibviri pasina nzira yekukurukurirana nekukurumidzira uye kushandiswa kwekurumidza kwemashoko. Global network network yakagadzirirwa kugadzirisa dambudziko iri. Mamiriro makuru ekushandiswa kwemashungetedzo aya ndiyo kuendeswa kwemashoko pakarepo, zvisinei kuti makombiyuta anenge abviswa sei kubva kune mumwe.

A global network is network inosanganisira makombiyuta ari munzvimbo dzakawanda dzine nhamba dzisingagumi zvemakombiyuta anotarirwa mumutambo. Nhanho yekufambisa dambudziko mumutambo wakadaro yakaderera kupfuura munharaunda yemo.

Mitemo yemakombiyuta

Global network networks inotsigirwa neTCP / IP, ATM, MPLS nevamwe. Inonyanyozivikanwa protocol ndiyo TCP / IP, iyo inosanganisira zvinyorwa. Icho chinoshandiswa subprotocol, kutakura, nhandare, kanhi uye muviri.

Zvizhinji zvepurogiramu dzinoshanda pachikwata chekushanda uye dzine maitiro avo pachawo. Izvi HTTP, WWW, nezvimwe. Mitemo ine basa rekuona uye kuratidza ruzivo rwakatsvaga.

Nzira yekufambisa protocol inovimbisa kuendeswa kwedhadha kune imwe shanduro inogona kuigadzirisa. Inonzi TCP.

Iyo IP network protocol inotarisira kugamuchira uye kutumira zvikumbiro kumatanho ari pasi kuti uwane mashoko ose anodiwa.

Nzira uye zvikamu zvepanyama zvine basa rekutarisa nzira uye mamiriro ekutumira mashoko.

Inozivikanwa pasi rese miteresi: somuenzaniso, WWW (WorldWide Web). Iyo mambure inoumbwa nemasevhisi anochengetedza ruzivo rwevashandisi vanoda, uye makombiyuta ega anogamuchira ruzivo kubva kumaseva uye oiraira iwo kwavari. IWWW network iri nyore uye iri nyore kushandisa.

Global network network dzinosanganisira subnet ine zvikamu zvakasiyana zvakadai sekukurukurirana uye kuchinja zvinhu. Mitsara yokukurukurirana inonzi yakanzi semigwagwa kana kumashure, data inofamba kubva kumashini kuenda kumichina.

Iko kushandiswa kwezvinhu zvinoshandiswa kubatanidza mitsara yekukurukurirana iri mahara. Aya ndiwo makombiyuta chaiwo.

Global network, inowanzo, ine nhamba huru yematarefoni uye tambo dzinobatanidza mairaji.

Chechipiri inogona kunge yakabatanidza routers ishizha redhiyo rinoshandisa satellites kana kudzokorora pasi. Router imwe neimwe ine antenna, iyo inogona kugamuchira uye kutumira chiratidzo. Network routers dzinogona kugamuchira nyore nyore zviratidzo kubva pane satellite, uye mune dzimwe nguva, dzinokwanisa kunzwa ruzivo rwakaparidzirwa rwevamiriri vevakidzani vanotumira mashoko kune satellite. Mukuparadzaniswa kwenyika yose, ma router ose anowirirana kune imwe nhatu pasi-innet subnet, uye imwe chete yadzo inopiwa antenna satellite. Shanduro dzemaStaneti dzinoparadzira uye dzinowanzodiwa pane kuparidzirwa kunodiwa.
