Tshaj tawm thiab kev sib tsoo domains ob qho tib si tshwm sim ntawm Data Link txheej ntawm OSI qauv. A tshaj tawm tus sau yog cov sau npe koj a tshaj tawm yog xa mus. A kev sib tsoo domain yog ib feem ntawm lub network uas pob ntawv kev sib tsoo tuaj yeem tshwm sim.
Tsis tas li ntawd, qhov sib txawv ntawm kev sib tsoo domain thiab tshaj tawm xov xwm yog dab tsi?
A kev sib tsoo tshwm sim thaum ob lub cuab yeej xa ib pob ntawv tib lub sijhawm ntawm ntu sib koom ua ke. Txhua qhov chaw nres nkoj ntawm tus choj, hloov lossis router yog hauv a cais kev sib tsoo domain . Tshaj tawm qhov chaw . A tshaj tawm tus sau yog a sau npe koj a tshaj tawm yog xa mus.
Qhov thib ob, dab tsi yog kev sib tsoo hauv Network? A kev sib tsoo domain yog a network ntu txuas nrog los ntawm kev sib koom nruab nrab lossis los ntawm kev rov ua dua qhov twg cov ntaub ntawv xa mus ib txhij sib tsoo nrog ib leeg. A kev sib tsoo network tshwm sim thaum ntau tshaj ib lub cuab yeej sim xa ib pob ntawv ntawm a network ntu tib lub sijhawm.
Hauv qhov no, muaj pes tsawg tus tshaj tawm thiab kev sib tsoo ntawm qhov hloov pauv?
Hloov: muaj ib qho kev tshaj tawm xov xwm (los ntawm def) & ib-chaw nres nkoj sib tsoo domain. Yog li, muaj 2 tshaj tawm domains & 5 Collision domains. Routers Muab Ib Daim Ntawv Tshaj Tawm cais rau txhua qhov interface.
Puas yog hubs tsim kev sib tsoo?
Hubs xa tawm cov ntaub ntawv rau txhua tus tswv ntawm ntu, tsim ib tug sib koom kev sib tsoo domain . Switches muaj ib qho kev sib tsoo domain ib qhov chaw nres nkoj thiab khaws cov lus chaw nyob ntawm MAC chaw nyob uas cuam tshuam nrog txhua qhov chaw nres nkoj.

Cell referencing yog dab tsi thiab dab tsi yog qhov sib txawv ntawm kev xa tawm?
Muaj ob hom kev siv ntawm tes: txheeb ze thiab tsis meej. Cov txheeb ze thiab cov ntawv pov thawj tseeb coj txawv txawv thaum theej thiab sau rau lwm lub hlwb.Cov ntaub ntawv txheeb ze hloov thaum tus qauv raug theej rau lwm lub xovtooj. Cov ntaub ntawv tseeb, ntawm qhov tod tes, tseem nyob tas li txawm tias lawv tau theej qhov twg
Social engineering yog dab tsi thiab nws lub hom phiaj yog dab tsi?
Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Daim ntawv teev kev sib pauv yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Daim ntawv teev kev lag luam yog cov ntaub ntawv sib txuas ntawm txhua qhov kev hloov pauv hauv cov ntaub ntawv thaum cov ntaub ntawv tiag tiag muaj nyob rau hauv cov ntaub ntawv sib cais. Daim ntawv teev kev lag luam muaj cov ntaub ntawv txaus los tshem tawm tag nrho cov kev hloov pauv tau ua rau cov ntaub ntawv cov ntaub ntawv ua ib feem ntawm ib qho kev sib pauv
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
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
