Chii bandwidth

rokuti "bandwidth" rinowanzoshandiswa wakaisirwa zvemagetsi kukurukurirana network kushandiswa. Uyu ndiwo mumwe kiyi zvatariswa zvakadaro gadziriro. Pakutanga zvingaita sokuti munhu ane basa haasi chokuita kukurukura mitsetse, hapana chikonzero kunzwisisa chii chiteshi bandwidth. Kutaura zvazviri, zvose zvishoma chakaipa. Vazhinji vane musha pachake kombiyuta kwakabatana kuti Internet. Uye vose vanoziva kuti dzimwe nguva kushanda ne "World Wide Web" pasina chikonzero iri tava kuderera. Chimwe chikonzero cheizvi ndechokuti panguva iyoyo boka Provider chiteshi bandwidth iri migweje. Izvi - a slowdown yakajeka uye pazvinobvira atadze kushanda zvakanaka. Asati kutsanangura pfungwa "bandwidth", kushandisa muenzaniso, anobvumira munhu kunzwisisa zviri pangozi.

Fungidzira huru muguta duku uye dzine vakawanda guru. Muchiitiko chokutanga, yakawanda iri rakagadzirirwa imwe kana mbiri Hova motokari, ukuwo, duku upamhi. Asi pamaguta makuru, kunyange zvina-mukoto haashamisi. Panguva iyo nhamba dzemotokari, kutyaira daro chete mumigwagwa maviri, zviri zvakasiyana. It zvinoenderana maitiro maviri - kumhanya uye nhamba vamapoka. In muenzaniso uyu, mugwagwa - a kukurukurirana mugero, uye michina ndiwo mashoko matomu. Uyewo, mumwe bhendi - kukurukurirana kubatana.

Nemamwe mashoko, bandwidth zvisina kunanga hunoratidza uwandu Data hunogona kutapukira pamusoro kudyidzana chiteshi muzana chikwata nguva. The yepamusoro parameter ichi, zvikuru akasununguka kushanda kuburikidza remubatanidzwa yakadaro.

Kana Kupfuudzwa yevanhu zvose pachena (izvozvo kunowedzera kuderera ari chiratidzo yedzimudzangara kunonoka), shoko rokuti "bandwidth" ndiyo zvishoma kupfuura kuoma. Sezvazvakanyorwa anozivikanwa kuti chiratidzo anogona kubudisa mashoko nenzira yakati, iye kushandurwa. Kushandisirwa zvemagetsi, kungava kakawanda, amplitude kana yakavhenganiswa vachisiyanisa inzwi. Zvisinei, mumwe nokupfuuridzirwa unhu ndechokuti mumwe chete kondakita, pulses akawanda anogona kuparadzirwa panguva imwe chete panguva frequencies dzakasiyana (mukati yose bandwidth sezvo kusarurama vari mukati zvinogamuchirika mwero). Nyaya iyi kunoita kuti kuwedzera zvinonyatsorehwa negoho kubatana pasina kuchinja kunonoka. A muenzaniso wakajeka wezvinotaurwa coexistence pakati frequencies - a mawa kukurukura nevanhu vanoverengeka vane akasiyana timbre. Kunyange zvazvo vose inoti, asi neshoko rimwe nerimwe riri zvikuru distinguishable.

Nei kushanda pamwe richikurukura dzimwe nguva tava kuderera kuchengetwa? All zvinotsanangurwa zvikuru nyore:

- dzakanga dziri latency, shoma nokukurumidza. Chero chipingaidzo chiratidzo ndima (software kana chaiko) kuderedza nokukurumidza;

- kazhinji date rukova anowedzera matomu kushanda nouya mabasa - vanonzi "redundancy". Izvi zvakakodzera kuitira vakarongeka kushanda mumamiriro ezvinhu ose pamberi ruzha pamutsetse;

- asvika kwomuviri panogumira kuitisa svikiro kana zvose bvumidzwa maitikiro neeSultan vari atoshandisa uye zvikamu itsva date vari Vakaisa tungamidzana kuti kutumira.

Kugadzirisa matambudziko aya rinobatsirwa vanoshandisa wandei mharidzo dzakasiyana. Izvi zvingava Virtualization, ichiwedzera "width" asi iro rinopa chimwe kunonoka; kuwedzera mugero nokuda "zvimwe" achiitisa vezvenhau nezvakadaro.

Shoko rokuti "baud" dzimwe nguva rinoshandiswa mune digitaalinen unyanzvi. Kutaura zvazviri, zvinoreva nhamba nhonga mashoko Kutamiswa muzana chikwata nguva. Munguva kunonoka yokukurukurirana mitsetse (dhayira-up) 1 bps anoenderana 1 ikakuruma muzana 1 wechipiri. Mune ramangwana, pamwe kukura zvazvingava, "baud" yakaguma kuva nokudenga. Zvinogona kureva 1, 2, 3 kana kupfuura matomu por wechipiri, yaida yoga chiratidzo, saka zvino kushandisa akasiyana gadziriro, zvinonzwisisika kuti munhu wose.
