Mumakore makumi maviri apfuura, nyika yakatanga kuvharwa nemakombiyuta maitiro akasiyana-siyana. Kunzwisisa zvidzidzo zvekushandiswa kwemasvomaneti aya kunotibatsira sei kudzidza zvakanaka kuti tishandise uye kunowedzerawo kuziva kwedu kuchinja kwenyika inotitenderedza. Izvi zvikamu zvehurukuro yedu pamusoro pekuti How Computer Networks Work inongororonga maikirwo - ma-hardware systems anowanirana kune network uye anotaurirana.
Chii Chinogadzira Network Device
Haisi kombiyuta yose, gadget yakachengetwa, kana chimwe chidimbu chemichina inokwanisa kubatana neukambani. A network network device ine hutano hukuru hwekushandisa hutano hunoita hunodiwa hunodiwa kune mamwe majaira. Nzvimbo dzakawanda dzemazuva ano mashandisirwo emagetsi ane magetsi ekukurukurirana akabatanidzwa pamapuranga emataundi.
Mamwe maPc, vakuru vekare Xbox game consoles, nezvimwe zvigadzirwa zvekare hazvive nehupfumi hwehutano huri hutano asi zvinogona kugadzirirwa semagetsi ekutengesa kuburikidza nekupinda mune zvakasiyana-siyana zvigadzirisiti zvemutauro nenzira ye USB piripheral. Yakakura kare pakombiyuta PC inoda kuisa muviri wakasiyana-siyana makadhi ekuwedzera-mu-system motherboard, inotangira izwi Interface Card (NIC) .
Zvizvarwa zvitsva zvezvigadzirwa zvemagetsi nemagadhari zviri kuvakwa semagadzirirwo emagetsi kana zvizvarwa zvekare zvisiri. Semuenzaniso, tsika dzepamba dzemapurisa dzakanga dzisingatauri hardware yekukurukurirana, uyewo dzingabatanidzwa neimba yekutengesa kuburikidza nedzimwe nharaunda.
Pakupedzisira, mamwe marudzi emidziyo haitsigire mitambo zvachose. Zvishandisi zvevatengi izvo hazvina kuvaka-in network hardware kana kugamuchira mitsara inosanganisira vakwegura Apple iPods, mafirivhi akawanda, uye mavheni emagetsi.
Dhidhiyo Dhigiriji paKuteerera Networks
Devices pamakombiyuta maitiro anoita mabasa akasiyana. Idzi mbiri idzi dzakawanda dzinoshandiswa nevashandi . Mienzaniso yevatengesi vatengesi vanosanganisira PC, mafoni uye mahwendefa, uye mapepa emichina . Vatengi kazhinji vanoita chikumbiro uye vanodya dhesi dzakachengetwa mumaseva emagetsi, zvishandiso zvinowanzogadzirirwa nezvakawanda zvekuyeuka uye / kana disk kuchengetedza uye kushandiswa kwepamusoro kwekutsigira zviri nani vatengi. Mienzaniso yemasevhisi ekubatanidza inosanganisira maSeva eWebhu nemaseva emutambo. Masoko anowanzotsigira vakawanda vatengi kupfuura vashandi. Vose vashandi nemaseva dzimwe nguva anonzi network nodes .
Network maikirwe angavewo akakwanisa kushanda sevashandi neveseva. Muwezera rekuongorora ushamwari, somuenzaniso, mapaundi ezvigadziro akagovera mafaira kana zvimwe zvakasiyana nemumwe, mumwe ari sevhareji achibata imwe data panguva imwe chete achishanda semuteresi kuti akumbire dambudziko rakasiyana kubva kune mamwe maitiro ezera rako.
Special Purpose Network Devices
Mutevedzeri uye nheyo dzeseva dzinogona kuwedzerwa kana kubviswa kubva pane network asi dzisingadziviri kutaurirana kwevamwe magadziri anenge achiripo. Dzimwe humwe mhando dzehutaneti hardware, zvisinei, zviripo nokuda kwechinangwa choga chekugonesa keseti kuti iite:
- Nhandare yakabatana inoita kuti nhamba ipi neipi yakabatanidzwa nayo kutumira zvakananga kune vamwe
- Network switches inoita basa rimwechete se hubs asi rinosanganisira mamwe manyore ehurumende anovhura nzira dzakawanda dzekukurukurirana dzinoita kuti mazamu akawanda akabatanidzwa atumire dhutano zvakananga kune mumwe kune mumwe pane kune vamwe vose pamusangano sekunge hubs
- Network routers inowedzera hukuru hwehutachiona shanduko nekusimbisa hukama hwekunze kubva kune imwe humwe kune mamwe mahutano, kuabatanidza pamwe chete pasina kuvhiringidza kushanda kweumwe neumwe mumwe nomumwe.
- A repeat network inogamuchira zviratidzo zvenyama zvinotumirwa kunhare yehutano uye inosimudza simba razvo (seyakadai semagetsi kana remhepo) kuitira kuti zviratidzo zvirambe kufamba marefu marefu
- Izvo zvinyorwa zvishoma zvishoma zvemazuva ano, bridge bridge device inobatanidza marudzi maviri akasiyana ehutachiona hunobatanidza pamwe chete zvingave zvisingaenderani, zvakadai semabhiriji anobvumira michina dzisina utsi kuti dzibatane newetaneti. (Mazuva ano bhulogi teknolojia inowanzobatanidzwa mune mamwe marudzi emafaira.)
