Qhov thib ob, vim li cas cov teeb meem queuing tshwm sim? Teeb meem Queing tshwm sim thaum qhov kev pabcuam tsis sib haum rau qib kev xav tau, piv txwv li thaum lub khw muag khoom loj tsis muaj neeg nqa nyiaj txaus rau thaum sawv ntxov tsis khoom. Hauv IT, teeb meem queuing qoob loo thaum thov mus txog qhov system sai dua li nws tuaj yeem ua tiav lawv.
Tib neeg kuj nug, dab tsi yog queue system thiab hais txog nws qhov tseem ceeb?
Qhov tseem ceeb ntawm queuing systems yog ob npaug. Hauv Qee qhov xwm txheej, tus neeg siv khoom yuav tsis xav rov qab mus rau kev lag luam uas tsis zoo, tsis muaj kev tswj hwm kab . Muab qhov zoo kab kev tswj hwm systems hauv qhov chaw pab automate lub queuing txheej txheem whilst txhim kho kev pabcuam thiab tau txais cov neeg siv khoom loyalty.
Koj txhais li cas los ntawm queuing system?
Hais lus dav dav, a queuing system tshwm sim txhua lub sijhawm 'cov neeg siv khoom' xav tau 'kev pabcuam' los ntawm qee qhov chaw; feem ntau ob qho tib si tuaj txog ntawm cov neeg siv khoom thiab lub sijhawm ua haujlwm yog suav tias yog random. Yog tias tag nrho cov 'servers' tsis khoom thaum cov neeg siv khoom tshiab tuaj txog, cov no feem ntau yuav tos hauv kab rau cov neeg rau zaub mov tom ntej.

Hauv kev nug txog kev tshawb fawb, kev xav txog kev txiav txim siab yog qhov tseem ceeb heev vim tias, txhawm rau daws cov teeb meem kev tshawb fawb, koj yuav tsum ua cov kev xav. Ntau qhov kev xav tsis tuaj yeem kuaj ncaj qha; koj yuav tsum txiav txim siab los ntawm qhov kev xav thiab ua qhov kev kwv yees uas tuaj yeem kuaj tau los ntawm kev sim
Vim li cas nws tseem ceeb rau tus programmer kom paub tias Java yog cov lus rhiab heev?
Java yog case-sensitive vim nws siv C-style syntax. Case rhiab heev yog qhov muaj txiaj ntsig vim nws tso cai rau koj nkag siab tias lub npe txhais li cas raws li nws qhov xwm txheej. Piv txwv li, Java tus qauv rau cov npe hauv chav kawm yog sau thawj tsab ntawv ntawm txhua lo lus (Integer, PrintStream, thiab lwm yam)
Lub teeb liab rau lub suab nrov yog dab tsi thiab vim li cas nws tseem ceeb?
Lub teeb liab rau lub suab nrov piv yog qhov tseem ceeb vim hais tias hauv kev sib txuas lus peb lub ntsiab tseem ceeb yog lub teeb liab tab sis thaum lub sij hawm kis tau tus mob tau cuam tshuam los ntawm qee lub suab nrov. Thaum kawg tau txais peb xav kom muaj tib lub teeb liab sib kis, kom ua tiav qhov no lub suab nrov yuav tsum tau txo qis thiab ntawm no SNR ua lub luag haujlwm tseem ceeb

Vim li cas yog vim li cas ib txoj hauv kev tseem ceeb ntawm kev paub?
Yog vim li cas thiaj paub. Yog vim li cas feem ntau suav hais tias tsis muaj nuj nqis los ntsuas seb qhov kev lees paub, lossis txawm tias tib neeg, puas ntseeg tau. Yog vim li cas qee zaum sib txawv nrog kev xav, qhov uas cov lus hais txog kev xav thiab kev xav zoo li yuav cuam tshuam peb txoj kev tshawb nrhiav kev paub; hloov peb ntawm 'qhov tseeb
