Computer network: huru unhu, kupatsanura nenheyo sangano

Modern vanhu kushanda haagoni kurarama pasina makombiyuta, uye chokwadi havana kudaro kare. Mumakore makumi maviri apfuura, makombiyuta vava chinokosha zvose nzvimbo: kubva muhofisi zvinodiwa dzidzo, nokudaro kusika kudiwa kuva mikana ruzivo kombiyuta uye kukudziridza akakodzera software.

A samambure makombiyuta zvaiita kwete chete kuwedzera negoho asiwo kuderedza mari yokuzvigadzirisa, uyewo kuderedza nguva yose date hutachiwana. Nemamwe mashoko, kombiyuta mambure ane zvinangwa zviviri: kugoverana Software uye Hardware, uyewo rakazaruka kuwana mashoko kupfuma.

Kuvaka network kombiyuta inobva papfungwa "nemhosva-Server". The yeGmail.END_STRONG - chinhu rokuti mapurani kuti ari kushandisa Login uye pasiwedhi inoshandisa nezvaanogona ari Server. The Server, akavapindurawo, inopa pfuma aro kuvatori vechikamu Network. Zvinogona iiswe, ndinosika nevakawanda Database, kushandisa mazano-goho, etc.

Networks kuuya munzira dzakawanda:

- omunharaunda;

- zvenharaunda;

- Global.

Pano, zviri zvakanaka kuratidza nhungamiro pamusoro ayo anobva siyana kombiyuta network.

The sangano vomunharaunda network kombiyuta

Kazhinji, network izvi kuunza pamwe chete vanhu vari pedyo napedyo, saka zvikuru yaiwanzoshandiswa mumahofisi uye mabhizimisi kuti kuchengetwa uye kubudiswa, tama migumisiro aro kuvatori vechikamu.

Pane kudaro chinhu se "zvakarukwa topology". Zvichitaurwa zviri nyore, ndiko geometric dhayagiramu ane richikurukura makombiyuta. Kune vakawanda zvirongwa zvakadaro, Zvisinei, isu funga chete inokosha: bhazi, mhete uye nyeredzi.

1. Bus - mugero yokukurukura kuti rinobatanidza nodes mu pemambure. Imwe neimwe nodes vanogona kugamuchira mashoko chero mukana, nekufambisa - chete kana bhazi akasununguka.
2. Ring. In topology ichi kushanda zviumbu chokuita mune dzinotevedzana iri denderedzwa, i.e. ravarwi rokutanga chokuita kune wechipiri nezvimwewo, uye yokupedzisira anokurukura wokutanga, nokudaro nokuvhara mhete. The chikuru drawback pamusoro mapurani ichi ndechokuti pamusoro kukundikana pane imwe chinhu yose samambure mitezo.
3. Star - remubatanidzwa panguva iyo nemwaranzi nodes chokuita pakati. Izvi kubatana wokuenzanisira kuenda nguva idzodzo kure, kana makombiyuta vaibudirira huru, uye chete mubereki muchina anogamuchira uye kufambisa mashoko.

Panyaya yose network, ipapo zvose zvakawanda kuoma. To musi, izvo kune vanopfuura 200. The kupfuura inozivikanwa vavo - Internet.

Musiyano mukuru kubva munharaunda womunharaunda - kushaya kiyi utariri centre.

Kwakadaro zvakarukwa kombiyuta rokuita basa iri nheyo maviri:

- zvirongwa Server takaisa padandemutande nzvimbo kuti kubata vanoshandisa basa;

- yeGmail.END_STRONG Zvirongwa akaisa pamusoro aishandisa PC uye Server vanoshandisa mabasa.

Global network kubvumira vanoshandisa kuwana mabasa akasiyana-siyana. Batanidza flow kwakadaro nenzira mbiri: kuburikidza paruzhinji kushandisa runhare dzakatsaurwa gwara.
