To connect computers ezimbini ezahlukeneyo ulwazi kufuneka amanqanaba 7 encryption efanayo - zokucazulula. Mphathe bonke ixesha elide, ngoko ke ugxininiso luya kuba licandelo elinye kuphela - zamasango. Yintoni ke, esebenzisa yintoni umsebenzi, yintoni iindidi kukho kwaye mnoe omnye kuya kuqwalaselwa njengenxenye inqaku. Kuba hetiseka wasengqondweni iindlela omncinane ngaxeshanye ayakuchatshazelwa nesihloko. Kuphela ukuze kujongwane ngcono kunye nokudluliselwa data.
Zamasango Routes
Ukuba ikhona enye imoto ebukeka kwindawo ethile kwinethiwekhi yekhompyutha. Ngesi mzekelo encinane, sifumanisa ukuba kuphuma ezinjalo. Needs inkcazo womatshini, ebonelela njengoko kuya kwenziwa enjalo yokosulela data. Wabiza umzila. Sibeke ne "idilesi yendawo" yaye "yesango". Ngaphezu koko, isixhobo ethile isetyenzisiwe ukufikelela kwinqanaba elifunekayo. Nantso into zamasango nokuba zisebenza njengenxenye ye computer. Kusenokubakho iindidi ezintathu iidilesi:
- A host olulodwa.
- Network.
- indlela engagqibekanga. Oku kusetyenziswa xa ingenakusetyenziswa kulophulo kwi iinketho zokuqala ezimbini.
Kukho iintlobo ezintathu kuphuma:
- yamabandla ngamnye.
- Ekudityaniswe kuzo.
- Mac-iidilesi.
imizila engagqibekanga
Digress isuntswana ukusuka isihloko ukuqonda ukusebenza yesango. Ingqalelo kufuneka ihlawulwe idilesi nganye. Kodwa ngumba eyahlukileyo, ngoko sithatha kuphela isiseko. Xa inkqubo wengingqi kwenzeka imfuneko yokuseka yokudityaniswa nginginya yobekelo kude, weposi onikeza itafile yomgudu ukufumanisa ukuba ikho. Ukuba le thagethi ezinye subnets iingenziwa ukudibanisa kuyo ukuqinisekisa ukutshintsha idata. Ukuba akukho nalunye lwezi iindlela ezaziwayo inokuba efanelekileyo, sebenzisa engagqibekanga. Ilungiselelwe ngokukodwa ukuba kungenzeka, esebenzisa uhlobo olulodwa yesango (omnye kuphela kwinkqubo), nto leyo ephawulwe C. iflegi Khankanya umatshini, nto leyo eye uqhagamshelwano ngqo womnatha kwihlabathi (njengezinto lowo angasenza ababoneleli), ngethemba lokuba kwindawo yokugcina yonke iya okufanayo wafunyanwa. Lo mgaqo transmission, into leyo eyenza ukuba baqonde ukuba yintoni na kwesango kwinethiwekhi, yaye indlela ekubaluleke ngayo ukuba ukwabelana ngolwazi.
YemiKhosi ezimbini-homed
Oku impela Uhlobo umdla lombutho yokosulela data, ngoko ke enomzami wokulungisa njengento zahlukileyo ziya kunikwa ezinye ingqalelo. Ukusuka kwindawo yezobugcisa lwembono, nawuphi na umatshini ukuba imisebenzi njenge ndlela yesango womnatha, kungathathwa njenge umkhosi kunye ombaxa-homed. Ukuziqhelisa, eli binzana zingasetyenziswa ukuchaza iikhompyutha kwiindawo ezimbini ezahlukeneyo. Ngoko ke, ngokuba bencwadi ityala kufuna ukuba umatshini uye amaqhoshana ezimbini Ethernet, yaye ngamnye kubo idilesi yayo kwi subnet efanayo. Ukunciphisa uluhlu lwezi mfuno kunokunceda ukusebenzisa iziteketiso e ifconfig (8). Enoba yonke into kuphunyezwa ngayo, ndilolonga umatshini imiselwa njenge ndlela yesango ezinokusetyenziswa ukuze ufake i subnet eyahlukileyo. Le ngobuwena yesekethe uluncedo kakhulu kwiimeko apho le nkqubo kudala ukhuseleko, lwepakethi izihluzi, kwaye ukwenza imisebenzi yodonga lomlilo kumacala omnye okanye emibini. Nzima? Noko ke, impendulo yombuzo "Yintoni ngesango Internet."
operation lock
Kwesango - le yinkqubo eqhelekileyo, Bulelani apho phambili ipakethe evela kwenye uqhagamshelwano ukuya kwenye. Ukuba athumele inkcazelo kufuneka ukuba 'bazi' yintoni na apho ufuna ukuya phambili. Ungasebenzisa iindlela ezingashukumiyo ukuba nazi, khumbula yesango ngasinye networking elula. Ukuze ezahlukeneyo ezininzi ezintsonkothileyo, imveliso yorhwebo ezahlukeneyo kunye nezixhobo abangabancedani (imizila, imizila, iiseva). Xa kufikwa ulwazi kwinethiwekhi omnye (ikhomputha), oko Iinkqubo idata wayengenakuyijika loo protocol ufihlo, ukuba kuyimfuneko, ukuze ukuba umamkeli wakwazi aqhelane umyalezo. Xa kwesango ifumana ulwazi, kube nokutshekishwa ukuba lowo senzelwe. Ukuba idilesi ichanekile, kukho ezidluliselwayo inxalenye efanelekileyo khompyutha kunye data kufundwa. Kwiimeko apho umamkeli omnye umntu, ulwazi uyaqhubeka. Indlela Ngaba ndiya kungagqibekanga esangweni le-computer? Ukuze wenze oku, yiya iimpawu uxhulumaniso, nto leyo ebonisa olu khetho.
isiphelo
Apha kwakhona siqonde ukuba yintoni Indlela yaye kutheni xa zifuneka. Ekugqibeleni sinokuthi ukuba ufuna ukusebenza nabo ngokobuqu ngokubhekiselele kwimiba zeenkqubo, ngengcamango efanelekileyo nomba iingxaki kuvela. Baya ukukhwela kuphela xa ukhangela, yintoni nokuba zenze amalungiselelo ngayo kwicandelo zekhompyutha a, ndinihlanganise / ibattery, ukuba oyifunayo. Oku akuthethi ubuncinane kwakungenxa yobumbaxa yayo. Ngoko ke, iya kuba yanele ukuba ufuna ukwenza uqwalasele ikhompyutha yakho ukuze sisebenze ngaphandle imiba enxulumene software uqwalaselo ezi zixhobo. Thina imibuzo ngaphezulu Sinethemba lokuba zokuphuma ezinjalo ihleli.
