Kuyini ukudayiswa kwenethiwekhi ye-Ring?

Inethiwekhi yokukhala isebenzisa indandatho eqhubekayo ukuxhuma idivayisi ngayinye ndawonye.Iqinisekisa ukuthi isignali ethunyelwe idivayisi eyodwa ingabonwa yiwo wonke amanye amadivaysi eringini.Ukuphindaphindeka kwenethiwekhi yeringi kubhekisela ekutheni iswishi iyayisekela yini inethiwekhi uma ukuxhumeka kwekhebula kuphazamiseka.Iswishi ithola lolu lwazi bese ivula imbobo eyisipele ukuze ibuyisele ukusebenza okuvamile kokuxhumana kwenethiwekhi.Ngesikhathi esifanayo, ukushintshwa okunamachweba 7 no-8 kunqanyuliwe kunethiwekhi, i-relay ivaliwe, futhi ukukhanya kwenkomba kuthumela i-alamu yamanga kumsebenzisi.Ngemuva kokuthi ikhebula lilungiswe evamile, umsebenzi we-relay kanye nokukhanya kwenkomba ukubuyela esimweni esivamile.

Ngamafuphi, ubuchwepheshe be-Ethernet ring redundancy bungenza esinye isixhumanisi sokuxhumana esingaguquki lapho isixhumanisi sokuxhumana sihluleka, okuthuthukisa kakhulu ukwethembeka kokuxhumana kwenethiwekhi.

Iyini iphrothokholi ye-IP?

Iphrothokholi ye-IP iphrothokholi eyenzelwe ukuthi amanethiwekhi ekhompyutha axhumane.Ku-inthanethi, isethi yemithetho eyenza wonke amanethiwekhi ekhompyutha axhunywe ku-inthanethi ukuthi axhumane, futhi icacisa imithetho amakhompyutha okufanele ayithobele lapho exhumana ku-inthanethi.Amasistimu ekhompyutha akhiqizwa yinoma yimuphi umkhiqizi angaxhuma ku-inthanethi inqobo nje uma ethobela umthetho olandelwayo we-IP.Izinhlelo zenethiwekhi nezinto zokusebenza ezikhiqizwe abakhiqizi abahlukahlukene, njenge-Ethernet, amanethiwekhi okushintsha amaphakethe, njll., azikwazi ukuxhumana.Ifomethi ihlukile.Iphrothokholi ye-IP empeleni iyisethi yesofthiwe yephrothokholi eyakhiwe izinhlelo zesofthiwe.Iguqula ngokulinganayo "ozimele" abahlukahlukene babe yifomethi "yedatha ye-IP".Lokhu kuguqulwa kungenye yezici ezibaluleke kakhulu ze-inthanethi, okuvumela zonke izinhlobo zekhompiyutha zifinyelele ukusebenzisana ku-inthanethi, kunezici "zokuvuleka".Kungenxa ngqo yephrothokholi ye-IP ukuthi i-inthanethi ithuthuke ngokushesha yaba inethiwekhi yokuxhumana yekhompyutha enkulu kunazo zonke emhlabeni, evulekile.Ngakho-ke, iphrothokholi ye-IP ingabuye ibizwe ngokuthi “Iphrothokholi Ye-inthanethi”.

Ikheli le-IP

Kukhona nokuqukethwe okubaluleke kakhulu kuphrothokholi ye-IP, okungukuthi, ikheli eliyingqayizivele licaciswe ikhompuyutha ngayinye nezinye izinto eziku-inthanethi, ezibizwa ngokuthi “ikheli le-IP”.Ngenxa yaleli kheli eliyingqayizivele, kuyaqinisekiswa ukuthi lapho umsebenzisi esebenza kukhompyutha enenethiwekhi, angakwazi ukukhetha ngokuphumelelayo futhi kalula into ayidingayo ezinkulungwaneni zamakhompiyutha.

Amakheli e-IP afana namakheli ethu asekhaya, uma ubhalela umuntu incwadi, udinga ukwazi ikheli lakhe ukuze uposi akwazi ukuletha incwadi.Ikhompiyutha ithumela umlayezo njengoposi, kufanele yazi “ikheli lasekhaya” eliyingqayizivele ukuze ingalethi incwadi kumuntu ongafanele.Ukuthi nje ikheli lethu ivezwe ngamagama, futhi ikheli lekhompyutha livezwa ngezinombolo kanambambili.

Ikheli lasesizindeni se-inthanethi lisetshenziselwa ukunikeza inombolo kukhompuyutha eku-inthanethi.Lokho wonke umuntu akubona nsuku zonke ukuthi yonke i-PC enenethiwekhi idinga ikheli le-IP ukuze ixhumane ngokujwayelekile.Singakwazi ukuqhathanisa "ikhompyutha yomuntu siqu" "nocingo", bese "ikheli lasesizindeni se-inthanethi" lilingana "nenombolo yocingo", futhi irutha eku-inthanethi ilingana "neswishi elawulwa ngohlelo" ehhovisi lezokuxhumana.
