Iri Computer Networks

An sani cewa daya daga cikin karni na karshe da ya fi muhimmanci nasarori ya daga halittar mutãne, kuma da m cin gaban bayanai fasahar - fasahar da cewa, yin amfani da kwakwalwa da kuma daban-daban iri kwamfuta networks, store, tsari, maida da kuma canja wurin yawa bayani. Shi ne ya kamata a lura da cewa irin wannan m Jump na bayanai mutãne ya zama zai yiwu ne kawai bayan da kwamfuta sadarwar networks an halitta.

Duk wani nau'i na kwamfuta cibiyoyin sadarwa ne mai tarin kwakwalwa rarraba kan wani yanki da juna ta qware tashoshi, kyale ka don canja wurin bayanai. Yau kwamfuta networks an yadu amfani, daban-daban iri kwamfuta networks aiki a duniya da kuma hulɗa tare da juna. Modern fahimtar fasali na networks, ya kai ga rarrabuwa da yankin manufa. A cewar wannan rarrabuwa ya hada da irin wannan iri kwamfuta networks:

Global Area Network (GAN) - a duniya cibiyar sadarwa na kwakwalwa da kuma wani cibiyar sadarwa located in sassa daban daban na duniya.

Wide Area Network (WAN) - manyan sikelin-networks da hada kwamfuta networks a matakin nahiyoyi da kuma kasashen.

Metropolitan Area Network (MAN) - dogon nesa networks na kwakwalwa da kuma cibiyoyin sadarwa a cikin sãsanni da kuma sauran administrative raka'a;

Local Area Network (LAN) - LAN, yana ambaton hadewa na kwakwalwa located a takaice in mun gwada nesa - misali, a cikin wannan gini.

WAN kuma MAN ne yankin da cibiyoyin sadarwa. Shi ne ya kamata a lura da cewa zuwa ranar, da rabo daga kwamfuta networks a cikin WAN kuma MAN ne sosai matukar, kamar yadda a yanzu kusan a kowace shiyya cibiyar sadarwa kunshe a wani duniya na cibiyar sadarwa.

Mutane da yawa kungiyoyi da suke da sha'awar samar da wani babban matakin bayanai kariya da encroachments daga waje (misali, da soja, bankuna, da dai sauransu), haifar da nasu networks, da aka sani da kamfanoni. A wani kamfanin sadarwa na iya hada dubban kwamfutar da cewa suna located a wani babba nesa daga juna, misali, a kasashe daban-daban.

The fi na kowa a duniya numerically ne gida kwamfuta cibiyoyin sadarwa.

Babban alama ne da yiwuwar gida yankin networks to connect kwakwalwa na USB ba tare da resorting to tashoshi for watsa bayanai, amfani da fadi da yankin cibiyoyin sadarwa (tarho na cibiyar sadarwa, fiber na gani na USB, rediyo watsa shirye-shirye da sauransu.). Tun da kwakwalwa suna located kusa da juna, don ƙirƙirar wani cibiyar sadarwa zuwa connect da isasshen na USB da kuma daidaita daidai da. Networking na kwakwalwa a kwamfuta cibiyar sadarwa IPLs ba ta mai da yawa abũbuwan amfãni.

Nau'in na gida kwamfuta networks yawanci raba wani topology - da hanyar da a haɗa kwakwalwa da juna. A topology ne mai muhimmanci halayyar gida networks, tun da shi ne m da hanyar da fili key Figures gabatar yi da kuma aiki AMINCI.

Babban amfani da cibiyar sadarwa sun yi bisa ga topology na "star" - to daya tsakiyar tushen an haɗa zuwa duk wasu kwakwalwa a kan hanyar sadarwa.

Akwai cibiyar sadarwa, kafa bisa ga topology na "zobe" - duk kwakwalwa sadarwa tare da juna a cikin jerin kuma ƙarshe samar da wani abu mai kama da zobe.

A na uku irin topology, wanda aka halitta da na gida kwamfuta networks, bas topology - duk kwakwalwa an haɗa ta da wani guda na USB - data bas.

Computer networks, yadda suke aiki, ladabi, da kuma hardware aka gyara an kullum ana inganta da kuma ci gaba.
