Hom ntaub ntawv . A hom ntaub ntawv yog a hom ntawm cov ntaub ntawv . Qee yam hom ntaub ntawv suav nrog integers, floating point tooj, cim, hlua, thiab arrays. Tej zaum lawv kuj yuav hais meej dua hom , xws li hnub tim, timestamps, boolean qhov tseem ceeb, thiab varchar ( sib txawv tus cwj pwm) formats.
Ntawm no, cov ntaub ntawv yog dab tsi?
Hom ntaub ntawv uas muaj xws li:
- Tus lej.
- Floating point tooj.
- Cim.
- Txoj hlua.
- Boolean.
Tsis tas li, cov ntaub ntawv hom lus yooj yim yog dab tsi? Los ntawm Wikipedia, phau ntawv dawb encyclopedia. Hauv computer science, hom ntaub ntawv los yog xwb hom yog ib qho kev faib uas txawv cov ntaub ntawv mus rau hauv tus nqi tiag tiag, integer lossis Boolean. Yuav luag txhua qhov programming yam lus meej meej suav nrog txoj kev xav ntawm hom ntaub ntawv , txawm txawv yam lus tuaj yeem siv cov lus sib txawv.
Ua li no, muaj pes tsawg hom ntaub ntawv muaj?
C lus txhawb 2 ntau hom ntaub ntawv hom : Thawj hom ntaub ntawv : Cov no yog qhov tseem ceeb hom ntaub ntawv hauv C xws li integer(int), floating point(float), character(char) and void.
Dab tsi yog hom ntaub ntawv siv rau?
Ib txoj hlua, piv txwv li, yog a hom ntaub ntawv uas yog siv los faib cov ntawv thiab tus lej yog a hom ntaub ntawv siv kom faib cov lej tag nrho. Cov hom ntaub ntawv txhais tau tias cov haujlwm twg tuaj yeem ua tau zoo los tsim, hloov pauv thiab siv cov sib txawv hauv lwm qhov kev suav.

DBMS muaj nyob rau sau, khaws, txheej txheem thiab nkag mus rau cov ntaub ntawv, cov khoom tseem ceeb tshaj plaws
Kev kwv yees thiab piav qhia cov ntaub ntawv mining yog dab tsi?
Descriptive Analytics siv cov ntaub ntawv Aggregation thiab Data Mining cov tswv yim los muab koj cov kev paub txog yav dhau los tab sis Predictive Analytics siv Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb kom paub txog yav tom ntej. Nyob rau hauv tus qauv Predictive, nws txheeb xyuas cov qauv pom nyob rau hauv cov ntaub ntawv yav dhau los thiab kev hloov pauv los nrhiav kev pheej hmoo thiab cov txiaj ntsig yav tom ntej
Packet Tracer yog dab tsi thiab piav qhia nws qhov zoo?
CISCO Packet Tracer yog "Network SimulatorSoftware". Cov software no qhia peb li cas kev sib txuas tuaj yeem teeb tsa thiab nws xav tau ntau heev yog tias koj tau kawm hauv CISCO. Nws muab lub sijhawm tiag tiag zoo li lwm yam khoom siv simulating. Advantage: Nws tuaj yeem siv rau txhua qhov chaw, koj tsis tas yuav nqa nws
