Chii chinonzi Modem? Musimboti kushanda. marudzi modems

Nguva yokutanga iwe batanidza chimwe Laptop kana PC kuti Internet zvakaipa aiziva vanoshandisa, sezvo mutemo, mubvunzo unomuka: "Chii chinonzi Modem uye nei vari zvinodiwa," Sechikamu ino achapiwa Modem kupatsanura, uyewo vachatitaka ive algorithm kwavo chokugadza configuration, achiita riri nyore kuti ruzivo kombiyuta nyanzvi inogona kusarudza uye kuwana kushanda zano rakadaro.

Chii?

Chokutanga, ngationei kubata chokuti modems dzakadaro. Ichi chaiyo pakuderedza iri kombiyuta, iro rakagadzirirwa riine nomumbure kombiyuta. Shoko "Modem" chakaumbwa tichibatanidza mazwi maviri. Wokutanga wavo - a modulator. Saka Electronics nayo inonzi chaiyo zano, iyo inofananidzira mureza. Uye chechipiri - a demodulator. Kureva, zano inoita Zvakaitwa Ivan Kuchin modulator. Mumwe wavo inofananidzira uye transmits chiratidzo, uye wechipiri anogamuchira navanodzoka. Saka, kusvikira ichangopfuura, kuti Internet dzakawanda pachake kombiyuta raiwanzobatana pachishandiswa waya runhare. Zvino zvinhu yachinja, uye zvishoma nezvishoma kusvinwa kubva kumusika chidimbu samambure makadhi. Ivo, uye nokukurumidza kwakakwirira, uye zvakawanda motherboard iri vakapakata navo. Asi pachine Wireless modems kuti haasati vane nzira chaiyo.

Kana iwe unodiwa?

Zvino ngatitarise kubata iwayo nyaya iyo inodiwa. Zvikurukuru, pfungwa idzi kungava zvitatu. Chokutanga izvi zvino zvishoma nezvishoma kutsakatika. Iye pachake kombiyuta achibatsirwa mudziyo uyu uye foni mutsetse zvakabatana Indaneti. Zvino akasunda NICs. Uye mutengo dererei, uye mwero iri kanoverengeka kwirirei. Uye kubatana kana ichi chinhu Unorudzi zvikuru nani. Asi nokuti hurongwa "Client-Bank" zano kwakadaro kunofanira (nyaya yechipiri). Pomoschm kana hwakabatana kusvikira zveakaunzi mari tsika Server. Pasina kusiya muhofisi, anogona kuita mari kuchinjirwa kana tarisa Kuwanikwa mari munhoroondo. High nokukurumidza mune iyi haisi kuzvireva. Asi kudzivirirwa papi chinodiwa panguva yakakodzera chechetere. Zvino masangano akawanda ari pamanyorerwo ichi uye basa pamwe nemabhengi. Zvapedzisira nyaya, kana modems iri kudiwa, kana munhu anofamba zvizhinji. Iye inoda Wireless Indaneti. Panyaya iyi, mubvunzo: "Chii chinonzi Modem, uye nei vari kudiwa" - unovapo woga. Achibatsirwa nevamwe unyanzvi nzira, mubvunzo uyu havangagoni kugadziriswa.

Mune nzira kuuraya

Mune nzira kuurayiwa kwakadaro mano akakamurwa mhando mbiri: zvemukati (i.e., ndakagadza mukati yekombiyuta chikwata) uye zvokunze (unobatanidza mudziyo kwakadaro kombiyuta kuwedzera slots rinoshandiswa, tablet kana piritsi). Nokuti zvapedzisira, unofanira kuisa Hardware chinja (kana) akakodzera nzvimbo. Uye zvinofanira kuva mubvunzo: "Chii Modem rudzi" Vane digitaalinen kana analoginen - iri pakutsvaga runhare chiratidzo. Wireless modems inowanika chete wokutanga navo. cellular network All ushande chete pomureza ichi. Naizvozvo, chakadaro chinja hakusi kuwanikwa Wireless mano. Imwe pfungwa zvinofanira kucherechedzwa. On motherboards vakura vari revatema (kureva, soldered) zvakafanana namano. Asi ikozvino havana hazvichaonekwi pamusoro bv itsva.

nokuti mirayiridzo unobatanidza

The kupatsanura wechipiri, wakange ari mukuru kuparadzirwa, kwakavakirwa nzira papi. Maererano ichi date Soup rakakamurwa wired that uye Wireless. Muchiitiko chokutanga pane connector chaiyo kuti foni netambo iri iiswe. Older mano anogona kuva nehurukuro pafoni kana basa paInternet. Zvino pane chinokosha nadzurudzo zvakadaro mano. Kunoitawo kuti panguva Surf Indaneti uye kukurukura runhare. Uyu ADSL-Modem. Chii? Special convert iyo anokamura nyaya uye inoparadzirwa chiratidzo panguva frequencies siyana. Somugumisiro zvakafanana maviri Nzizi umboo chakasvitswa kune waya. Kana yechipiri, humboo yedzimudzangara inopiwa remagetsi nemwaranzi pasina waya.

By mhando akatsigira network

Ipfungwa Izvi chete classifies Wireless namano. Maererano naye, vane marudzi anotevera: GSM (vari uyewo dzimwe nguva anonzi 2G), 3G uye LTE (4G nderimwe zita). Vose nenhendashure inowirirana mumwe. Kureva 3G nyore kukwanisa kushanda ari GSM Network. Uyewo, apo vanoshandisa zvakamushamisa chokwadi kuti USB-Modem. Zviri ichi chimiro chakaita kuti vakawanda vakadaro mano. In nechitarisiko chiri nokupenya nemotokari kuti anopa Wireless mashoko. Chokwadi zviri nepokuongorora slots nokuda SIM kadhi. Batanidza kusvika rectangular connector YUSB PC.

vagadziri

Conventionally, Vagadziri midziyo yakadaro inogona kukamurwa makirasi maviri. Wokutanga vavo - inotengeka uye zvishoma-anozivikanwa muchiso mazita, izvo zvinosanganisira Sierra (mutengo rinotanga kubva 180 rubles) uye yokungoi- ta bara (mari yakadaro mano ndiyo 120-150 rubles). Asi kirasi yechipiri - yakakurumbira uye yepamusoro namano. Ivo vanotengeswa pasi pezvitsiga Pantech uye Huawei. Mutengo kwatova rubles 600 uye kupfuura. Asi ichi ichokwadi kuti Wireless mano. Kazhinji mubvunzo unomuka, chii 3G-Modem. Izvi Mudziyo vakasiyana (chaizvo zvakafanana rutanda pachena), icho ndakagadza muna SIM kadhi iri foni worunhare wacho uye kurishandisa runoita kukurukura paIndaneti. Uyewo, pakati that no wired mano akaipa hunodzorwa "D-Link" uye "A-Corp". Zvinokurudzirwa kuti kuteerera kana kutenga mudziyo yakadaro. Mutengo nevamwe yokutevedzera mu chidimbu ichi inotanga kubva 120 rubles. Hwavo. kwakakwana.

kuchinja

Funga nzira nokuda nokuisa Internet Modem. Chii Internet Modem? Izvi zvose tiri, pasina chaakasiya mano mukirasi ichi: zvose that no wired uye Wireless. Saka, sei kuti kugadzira:

• Connection. Nokuti kwokunze - ndiko kuisa navo mukuwedzera slots yacho kadambari mudziyo. Asi kana kugadzwa zvakadaro womukati mano vanofanira kubvisa kurutivi butiro pauzima yekombiyuta Unit, kuisa kadhi riite kuwedzera slots, kuchigadzira uye kuungana nayo zvose.
• Kugadzwa vatyairi. Kazhinji zvinotora nzvimbo choga, uye rokushandisa kuita izvi zviri kushoma. Panopera unofanira kuona shoko pamusoro anobudirira kugadzwa software. (Kana harungaregi, ipapo anofanira kuiswa manually kubva CD kana kubva paIndaneti.)
• Next, batanidza Indaneti.
• Panguva yokupedzisira padariro nezvekutanga munhu Browser uye tarisa chokupika papi.

Mune zvimwe zviitiko zvinokosha kuchinja pazviruva devaysa basa (somuenzaniso, kuchinja nzira muchiuto analoginen kuti digitaalinen). ruzivo urwu zvazvakaipira pamwe Mugoveri uye Mutekenyi worunhare.

pfupiso

Nyaya iyi yave akapindura mubvunzo chii modems uye nei vari kudiwa. The zvinobvira Kuurayiwa kwakadaro mano. Akaratidza modes dzavo nokushanda nezvimwe michina maitiro. Inojekesawo setup algorithm, zvinotevera izvo zvinoita kuti kugadzira nyore zano kuti unobva kuna pemambure.
