Lw lawv los ntawm thiab rau

Koj puas paub yuav ua li cas peb tau txais kev nkag mus rau cov ntaub ntawv muab tso rau hauv Internet? Thiab yuav ua li cas cov ntaub ntawv yog exchanged? Ntawm no koj sau ib cov lus thiab xa nws. Yuav ua li cas koj xav hais tias, nyob rau hauv dab tsi tsim nws mus los ntawm ib lub computer mus rau lwm?

Twb yog tsis muaj daim card tias lub hauv paus ntawm tag nrho cov hluav taws xob ntaub ntawv yog binary (binary) code. Nws txhais lus nyob rau hauv hluav taws xob theem yog txo mus rau elementary: 1 - muaj ib tug tam sim no, 0 - tsis muaj tam sim no. Ntxiv mus, qhov no code yog yuav me me, thiab lawv ntxiv mus rau bytes - qhov tsawg kawg nkaus addressable unit ntawm cov ntaub ntawv. Raws li lub network, cov bytes yog kis twb nyob rau hauv daim ntawv ntawm cov ntaub ntawv packets.

Cov ntaub ntawv packets yog tsis nyob rau hauv cov huab cua. Yuav kom cia ntaub ntawv hais txog cov nplooj ntawv web siv servers, thiab txawm tag nrho neeg rau zaub mov network. Tam sim no ntxiv no tus kws kho mob lub neeg rau zaub mov. Tej zaum, mus qhib rau koj lub computer, lub website, nws yog tsim nyog los dhau ntau tshaj ib tug teb xws servers. Thiab, hmoov tsis, tsis yeej ib txwm nws puv tawm.

Yog hais tias koj tsis tau mus saib koj qhov profile Vkontakte, nws yog tsis zoo li hais tias koj yuav xav kom koj paub uas neeg rau zaub mov nyob rau hauv txoj tau ua tsis tau tejyam. Koj cia li kaw qhov tab thiab xav ib yam dab tsi lwm tus. Tab sis lub koom haum saib xyuas ntawm lub tsev kawm ntawv yog ib qho tseem ceeb kom paub tias yog vim li cas cov neeg tsis tau mus saib. Thiab ces lawv feem ntau siv ib lub cuab tam xws li tej qhov cim tseg txoj kev mus rau lub site.

Nyob rau hauv lub qhov rais, txoj kev ua no yog tau siv cov console «tracert» pab neeg. Yuav kom ib txoj lw, peb yuav tsum paub lub web chaw nyob ntawm qhov chaw los yog ntawm lub neeg rau zaub mov. Ntxiv mus, nyob rau hauv lub "Start" ntawv qhia zaub mov hu qhov hais kom ua kab ntawm lub "Khiav". Peb nkag mus rau «cmd», thiab nyob rau hauv lub qhov rais uas zoo nkaus li nrhiav «tracert nuzhnyy_adres". Tom qab ib co sij hawm, peb yuav tsum tau ib tug ua tiav daim ntawv teev cov servers, los ntawm kev uas peb tej pob khoom ntawm cov ntaub ntawv, thiab yuav qhia tau tias lub teb lub sij hawm ntawm txhua tus ntawm lawv.

Yog hais tias cov ntaub ntawv kis tau tus mob yog qeeb, peb yuav txiav txim uas neeg rau zaub mov nws slows cia. Yog hais tias koj siv ib tug router, cov thawj nyob rau hauv daim ntawv teev yuav nws qhov chaw nyob. Nws yuav tsum tshwm sim tam sim ntawd thaum pib ntawm lub lag luam, Yog hais tias qhov no tsis tshwm sim, ces qhov teeb meem yog muaj. Pib dua lub ntaus ntawv los yog txuas ncaj nraim, ces sim mus rov qab pib dua.

Txoj lw lawv yuav tso tau saib tag nrho cov teeb meem. Yog hais tias ib tug neeg rau zaub mov yog tsis teb, ces qhov no yuav tsum los sib tham. Siv ib tug zoo zoo, uas yog tswv rau neeg rau zaub mov - site los yog koj ISP. Yog hais tias tus tom kawg, ces nws yog lub sij hawm mus hu thiab tsis txaus siab, cia lawv daws qhov teeb meem. Thiab txawm zoo dua lw txoj kev mus rau lub DNS- thiab VPN neeg rau zaub mov (yog tias siv), yuav tsum paub tseeb tias tus kws kho mob yog tawm ntawm kev txiav txim.

Piv txwv li, txij li thaum tracing google.com site zoo nyob rau hauv kuv:

Raws li ib tug tshwm sim ntawm txoj kev rov cim tseg yog muaj kev vam meej. Raws li koj tau pom, cov ntaub ntawv no ua ntej mus dhia los ntawm ib tug ob peb ISP lub servers, ua ntej koj mus rau lwm tus neeg servers.

Tej zaum koj twb tau hnov txog xws li ib tug muaj nuj nqi raws li ib tug network txoj lw. Yuav ua li cas yog nws? Qhov no yog tsis yog tib yam li hais tias sib tham saum toj no txoj lw txoj kev. Qhov no yog nej ib tug pab tau feature yuav pab taug qab lub tsheb uas siv los ntawm daim ntawv thov, thiab muab ib tug ncauj lus kom ntxaws qhia rau lub chaw ua hauj lwm ntawm lub network daim ntawv thov. Qhov cuab yeej no yuav pab tau rau daim ntawv thov developers ua hauj lwm nrog cov network.
