Txhawm rau teeb tsa kev sib txuas lus, txhua tus txheej txheem yuav tsum xub tsim ib qho lub qhov (socket) .. Cov lub qhov (socket) .() system hu yog siv los ua qhov no. Kev ua haujlwm qhov system tiag tiag tsim cov lub qhov (socket) . thiab rov qab cov lub qhov (socket) . ID rau cov txheej txheem, kom nws tuaj yeem xa mus rau qhov tsim nyog lub qhov (socket) . thaum xa thiab tau txais cov lus.
Dhau li ntawd, koj txhais li cas los ntawm lub qhov (socket system hu)?
Ib lub network lub qhov (socket) . yog ib qho kawg ntawm kev sib txuas lus ntawm ob qhov kev pab cuam uas khiav hauv lub network. Qhov (socket) yog tsim thiab siv nrog ib txheej programming thov los yog "function hu " qee zaum hu ua cov qhov (socket) . daim ntawv thov programming interface (API).
Dab tsi yog qhov system hu hauv operating system? Hauv kev suav, a system hu yog txoj kev programmatic uas lub khoos phis tawj program thov kev pabcuam los ntawm cov ntsiav ntawm lub kev khiav hauj lwm qhov system nws raug tua rau. Nws muab ib tug interface ntawm ib tug txheej txheem thiab kev khiav hauj lwm qhov system tso cai rau cov neeg siv cov txheej txheem los thov cov kev pabcuam ntawm cov kev khiav hauj lwm qhov system.
Ua raws li qhov no saib, lub qhov (socket) hu ua dab tsi hauv Linux?
lub qhov (socket) .() tsim qhov kawg rau kev sib txuas lus thiab xa rov qab cov ntaub ntawv piav qhia uas hais txog qhov kawg ntawd. Cov ntaub ntawv piav qhia rov qab los ntawm kev ua tiav hu yuav yog tus lej qis tshaj cov ntaub ntawv piav qhia tsis tau qhib rau cov txheej txheem tam sim no. Cov lub qhov (socket) . muaj hom qhia, uas qhia txog kev sib txuas lus semantics.
Dab tsi yog qhov (socket) thiab nws hom?
Hom qhov (socket) .. Hom qhov (socket) . txhais cov khoom sib txuas lus pom rau tus neeg siv. Peb hom ntawm cov qhov (socket) . muaj kev txhawb nqa: Kwj cov qhov (socket) . tso cai rau cov txheej txheem sib txuas lus siv TCP. Ib kwj lub qhov (socket) . muab bidirectional, txhim khu kev qha, sequenced, thiab unduplicated flow ntawm cov ntaub ntawv uas tsis muaj cov ntaub ntawv ciam teb.

Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Yuav ua li cas yog ua nyob rau hauv lub system tsom xam theem ntawm kev txhim kho system?
Kev Ntsuam Xyuas Qhov System Qhov no suav nrog kev kawm txog cov txheej txheem kev lag luam, sau cov ntaub ntawv ua haujlwm, nkag siab cov ntaub ntawv ntws, nrhiav cov kev tsis sib haum xeeb thiab hloov kho cov kev daws teeb meem rau kev kov yeej qhov tsis muaj zog ntawm qhov system kom ua tiav cov hom phiaj ntawm lub koom haum

Yog hais tias nws yog ib qho kev hloov rau lub qhov (socket) tawg / faulty, ces tsis muaj txoj cai txwv tsis pub leej twg hloov nws, txawm tias koj lub tsev lossis koj cov phooj ywg. Nws yog dab tsi yog classed li tu
Puas yog lub qhov (socket) npog muaj kev nyab xeeb?
Kev siv cov npog negates cov kev ntsuas kev nyab xeeb uas twb muaj lawm nyob rau hauv daim ntawv ntawm kev tiv thaiv shutters, nthuav tawm cov hluav taws xob nyob. Cov npog tuaj yeem xoob lossis raug tshem tawm yooj yim los ntawm cov menyuam yaus, ua rau muaj kev pheej hmoo ntawm hluav taws xob. Npog tuaj yeem ua rau lub qhov (socket) puas, uas yuav ua rau muaj cua sov thiab muaj kev pheej hmoo ntawm hluav taws
