Lenethiwekhi yekhompyutha imiqondo eyisisekelo

Umlando amanethiwekhi computer has kwaqala kusukela esikhathini ukuqonda komuntu kudingeka sibe munye Computing, kanye nezinye izici amakhompyutha ambalwa ukusebenza ndawonye esiningi ulwazi, kanye isitoreji, ukucubungula ukudluliswa esiningi idatha. ikhompyutha zokuxhumana sici okuthwala ezihlukahlukene ulwazi, kodwa mhlawumbe yezingxenye ezibaluleke kakhulu, okuyinto zihlanganisa inethiwekhi yekhompyutha imiqondo eyisisekelo ukuze kwakhiwe iluphi okuzoxoxwa ngalo ngezansi, imikhiqizo interworking.

Ukuphishekela ndaba eyinkimbinkimbi ezifana amanethiwekhi computer nemiqondo eyisisekelo odinga ukukwazi nje. Ngaphandle lolu lwazi, inethiwekhi akasoze ukusebenza njengoba kufanele, futhi lokhu kuhilelani Silahlekelwe kakhulu ngayo isikhathi nezinto zethu ibhizinisi.

Ngakho, nemiqondo eyisisekelo amanethiwekhi computer - interworking izindlela. Kuyaphawuleka ukuthi amanxeba lezi amadivaysi ingenye zikhula esheshayo. The main injongo izimali interworking ukunikeza isixhumanisi phakathi kwabasebenzisi, abanobunye omkhulu, futhi ngokuvamile basakaza endaweni enkulu kwenethiwekhi yasendaweni.

lenethiwekhi yekhompyutha imiqondo eyisisekelo zihlanganisa izinhlobo eziyisithupha imikhiqizo, kwetfula interworking.

ukuphinda

Repeater ibizwa ngokuthi idivayisi hardware ukuthi isebenza ungqimba ngokomzimba OSI imodeli futhi inikeza kungenzeka ukugoqa pair inethiwekhi umsindo izingxenye.

concentrators

Umsebenzi concentrators kungumsebenzi yesifunda obandayo, okunikeza uxhumano ngayinye ingxenye asizayo futhi idivayisi inethiwekhi. Kunezinhlobo eziningana concentrators amela le yokwenziwa, esebenzayo futhi behlakaniphile.

amabhuloho

Leli gama lisho indlela okuyinto zenzelwe ukudluliselwa amaphakethe idatha phakathi amanethiwekhi ezimbili. Bridges enze kube nokwenzeka ukuba nesimo lapho izinhlelo kanye yezifiso ucabangela inethiwekhi elihlangene iyonke. Ngaphezu ukuthumela idatha, amabhuloho zingenziwa zokuhlunga.

imizila

Nge imizila eyenziwa uxhumano okunengqondo edingekayo kumanethiwekhi ezihlukene. Ngesikhathi esifanayo amanethiwekhi united ukusebenzisa olandelwayo efanayo. Kuyacaca ukuthi router - ke protokolozavisimye kudivayisi, okumele abanalo ikhono ukulondoloza ezithile umzila yezifiso. Kuyinto khona imizila e inethiwekhi njengomhlatshelo kwenza kube nokwenzeka ukuba khona sebuningini iphakethe yokudlulisela izindlela. Ngaphezu kwalokho i-router - "elihlakaniphile" idivayisi ekwazi ukunquma indlela kahle ephaketheni ngalinye kusukela anhlobonhlobo imizila kungenzeka.

kuphuma

Inchazelo ezivame kakhulu igama elithi "lomasango i-", ulandisa lokhu umqondo kunoma hardware noma isofthiwe iphakethe, yakhelwe ukuhlanganisa pair of izinhlelo nezingahlobene. Ngalo mqondo, esangweni angabhekwa iseva abezindaba noma ukufinyelela iseva.

Iqiniso lokuthi umsebenzi kwama ezahlukene "egqinsiwe" kuwabeke imizila, amabhuloho futhi ukuphinda ukuthi kungaba usebenza kuphela ezingeni elilodwa sabaphathi (lokhu kungaba inethiwekhi, isiteshi noma ungqimba ngokomzimba, ngokulandelana). Ngaphezu kwalokho imizila, amabhuloho, ukuphinda abakwazi ukwenza idatha ukuguqulwa.

ukushintshwa

Shintshela - idivayisi injongo zawo ezinkulu ukuqondisa kabusha idatha okokufaka komunye Imiphumela. Ngokwesibonelo, e-amaphakethe idatha inkinobho okokufaka wathola, futhi okhiqizwayo ixhunywe ibhasi-Ethernet. Kulesi samuntu, idivayisi uzobe eyaziwa ngokuthi ngesishintshi-Ethernet

Inkinobho kumele kube indlela samanje ukuhlela ukuxhumana kudingeka, kanye namathuluzi ukuguqula Imininingwane okokufaka ku isakhiwo esilungile nomkhiqizo.
