RSTP sib hloov sai dua vim hais tias nws siv ib tug handshake mechanism raws li point-to-point links es tsis txhob ntawm timer-raws li txheej txheem siv los ntawm STP . Rau cov tes hauj lwm nrog virtual LANs (VLANs), koj tuaj yeem siv VLAN Spanning Tree Protocol (VSTP), uas coj txoj hauv kev ntawm txhua VLAN rau hauv tus account thaum xam cov kev.
Tsis tas li ntawd, qhov txawv ntawm STP thiab RSTP yog dab tsi?
ib txawv yog tias Rapid Spanning Tree Protocol ( RSTP IEEE 802.1W) xav tias peb lub Spanning Tree Protocol ( STP ) ports states Listening, Thaiv, thiab Disabled yog tib yam (cov xeev no tsis xa Ethernet thav ntawv thiab lawv tsis kawm MAC chaw nyob).
Tsis tas li ntawd, vim li cas peb thiaj siv STP raws tu qauv? Spanning Tree Protocol ( STP ) yog Layer 2 raws tu qauv uas khiav ntawm cov choj thiab cov keyboards. Lub hom phiaj tseem ceeb ntawm STP yog kom paub meej tias koj tsis txhob tsim loops thaum koj muaj ntau txoj hauv kev hauv koj lub network. Loops tuag rau lub network.
Kuj nug, Rapid STP yog dab tsi?
Rapid Spanning Tsob Ntoo raws tu qauv ( RSTP ) yog lub network raws tu qauv uas ua kom lub voj-dawb topology rau Ethernet tes hauj lwm. Tam sim no nws yog ib qho kev daws teeb meem nrov los siv cov kev sib txuas tsis tu ncua hauv cov tshuab tseem ceeb rau Zog, Aerospace lossis Hoobkas Automation. Cov txheej txheem no tau muab tso rau hauv IEEE 802.1Q-2014.
RSTP raws tu qauv ua haujlwm li cas?
RSTP ua haujlwm los ntawm kev ntxiv lwm qhov chaw nres nkoj thiab qhov chaw nres nkoj thaub qab piv rau STP. Cov chaw nres nkoj no tau tso cai nkag mus rau hauv lub xeev xa mus tam sim es tsis txhob tos kom lub network sib txuas. * Lwm qhov chaw nres nkoj - Ib txoj hauv kev zoo tshaj plaws mus rau tus choj hauv paus. Txoj kev no txawv dua li kev siv lub hauv paus chaw nres nkoj.

Vim li cas symmetric encryption sai dua asymmetric encryption?
Rau cov txheej txheem encrypt / decrypt lub luag haujlwm, symmetrical algorithms feem ntau ua tau sai dua li lawv cov asymmetrical counterparts. Qhov no yog vim lub fact tias asymmetric cryptography yog loj heev inefficient. Symmetric cryptography yog tsim los rau kev ua haujlwm zoo ntawm cov ntaub ntawv loj
Vim li cas thiaj siv kev txhim kho sai sai?
Qhov ntawd yog qhov laj thawj tseem ceeb vim li cas software xav tau cov qauv kev txhim kho zoo kom ua tau zoo los ntawm kev tsim mus rau kev tshaj tawm. Kev txhim kho sai ntawm daim ntawv thov tau tsim rau lub hom phiaj no - txhawm rau tsim cov qauv sai sai rau kev sim ua haujlwm thiab cov yam ntxwv, tsis tas yuav txhawj xeeb txog qhov khoom kawg yuav cuam tshuam li cas
Vim li cas node js sai dua PHP?
Js vs PHP: Kev ua tau zoo. PHP muab qhov kev ua haujlwm ruaj khov thiab txhim khu kev qha thaum nws los txog rau lub vev xaib kev txhim kho, piv rau Javascript moj khaum.Txawm li cas los xij, thaum ob qho tib si ib puag ncig sib piv, koj yuav pom tias NodeJs sawv tawm sai dua PHP, vim yog USPs hauv qab no: Ceev phooj ywg V8 cav
Vim li cas kotlin sai dua Java?
Rau kev ua kom huv si nrog Gradle daemon sov so, Java compiles 13% sai dua Kotlin. Txawm li cas los xij, txawm hais tias koj siv hom lus twg, Gradle daemon yuav txo cov sijhawm tsim los ntawm ntau dua 40%. Yog tias koj tsis siv nws lawm, koj yuav tsum yog.Yog li Kotlin suav nrog qeeb me ntsis ntawm Java rau fullbuilds
Vim li cas kev sim tsav kev txhim kho ua rau kev txhim kho sai dua?
TDD pab tsim kom zoo dua modularized, extensible thiab saj zawg zog code. Test Driven Development mus kom ze tsav cov pab pawg Agile los npaj, tsim thiab sim cov chav me me kom sib koom ua ke ntawm theem siab. Raws li txoj hauv kev no, cov tswv cuab cuam tshuam xa thiab ua tau zoo dua vim tias tau tsom mus rau lub tsev me me
