Hauv Circuit Court hloov , txhua chav tsev cov ntaub ntawv paub tag nrho cov chaw nyob uas yog muab los ntawm qhov chaw. Hauv Packet switching , txhua chav tsev cov ntaub ntawv tsuas yog paub qhov kawg qhov chaw nyob nruab nrab ntawm txoj kev yog txiav txim siab los ntawm routers. Hauv Circuit Court hloov , cov ntaub ntawv yog ua tiav ntawm qhov system nkaus xwb.
Tsis tas li ntawd, qhov txawv ntawm pob ntawv hloov thiab hloov hluav taws xob yog dab tsi?
Circuit Court hloov thiab pob ntawv hloov yog ob tug hloov txoj kev uas siv los txuas ntau yam kev sib txuas lus nrog ib leeg. Lub ntsiab qhov sib txawv ntawm Circuit Court switching thiab pob ntawv hloov yog tias Hloov Circuit Court yog kev sib txuas oriented whereas, Packet Switching yog txuas tsis tau.
Ib yam li ntawd, txhais li cas los ntawm kev hloov hluav taws xob? Circuit Court hloov yog ib txoj hauv kev siv lub xov tooj sib txuas lus uas ob lub network nodes tsim kom muaj kev sib txuas lus tshwj xeeb ( Circuit Court ) los ntawm lub network ua ntej cov nodes tuaj yeem sib txuas lus.
Hauv qhov no, qhov kev hloov hluav taws xob puas siv pob khoom?
Lub ntsiab kom zoo dua uas pob ntawv hloov muaj dhau lawm Circuit Court hloov yog nws efficiency. Pob ntawv tuaj yeem nrhiav lawv tus kheej txoj hauv kev mus rau lawv lub hom phiaj yam tsis tas yuav muaj lub siab nyiam channel. Nyob rau hauv sib piv, nyob rau hauv Circuit Court hloov cov khoom siv network tsis tuaj yeem siv channel mus txog thaum lub suab sib txuas lus tau raug txiav.
Vim li cas peb thiaj xav tau pob ntawv hloov?
Pob ntawv - hloov networks - networks uas rhuav cov ntaub ntawv mus rau hauv chunks hu ua pob ntawv ua ntej kev thauj mus los - pab ua kom koj kev lag luam kev sib txuas lus ruaj khov thiab ua haujlwm tau zoo. Ib zaug tsuas yog siv rau cov ntaub ntawv thov, pob ntawv - switching yog nce siv los ua ib txoj hauv kev thauj cov suab thiab video sib txuas lus hauv lub sijhawm.

Dab tsi yog ob qhov zoo ntawm pob ntawv hloov dua li kev hloov pauv 2?
Lub ntsiab kom zoo dua uas pob ntawv switching muaj tshaj circuit switching yog nws efficiency. Cov pob khoom tuaj yeem nrhiav tau lawv tus kheej txoj hauv kev mus rau lawv qhov chaw nyob yam tsis tas yuav muaj lub vev xaib tshwj xeeb. Nyob rau hauv sib piv, nyob rau hauv circuits switching tes hauj lwm pab kiag li lawm siv tsis tau cov channel kom txog thaum lub suab sib txuas lus tau raug txiav
Dab tsi yog connectionless lossis datagram pob ntawv hloov?
Packet switching tej zaum yuav raug cais mus rau hauv kev sib txuas tsis muaj pob ntawv hloov, tseem hu ua datagramswitching, thiab kev sib txuas-taw qhia txog pob ntawv hloov pauv, tseem hu ua virtual circuit switching. Inconnectionless hom txhua pob ntawv tau sau nrog qhov chaw nyob, qhov chaw nyob, thiab cov lej chaw nres nkoj
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Cov ntaub ntawv hloov pauv thiab cov ntaub ntawv master yog dab tsi?
Definition of: pauv ntaub ntawv. kev hloov pauv. Ib qho kev sau ntawm cov ntaub ntawv sib pauv. Cov ntaub ntawv intransaction cov ntaub ntawv yog siv los hloov kho cov ntaub ntawv tus tswv, uas muaj cov ntaub ntawv hais txog cov ntsiab lus ntawm lub koom haum (cov neeg siv khoom, cov neeg ua haujlwm, cov neeg muag khoom, thiab lwm yam)
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
