VNC yog dab tsi?
VNC yog daim ntawv thov sib koom ua ke, uas muaj cov neeg siv graphical interface (GUI) kom nkag mus tau deb thiab tswj hwm lwm lub khoos phis tawj siv RFB (cov chaw taws teeb tswj hwm) raws tu qauv. VNC daim ntawv thov txuas ob lub khoos phis tawj thiab tom qab ntawd xa cov keyboard thiab nas cov xwm txheej hauv ib qho kev taw qhia thiab graphical screen hloov tshiab hauv lwm qhov kev taw qhia hauv lub network.

VNC feem ntau yog siv rau lub hom phiaj xws li nkag mus rau lub khoos phis tawj ua haujlwm hauv tsev thiab muab kev txhawb nqa tej thaj chaw deb.
Qhov txawv ntawm Chaw Taws Teeb Desktop thiab VNC yog dab tsi?
Txawm hais tias ob qho tib si Chaw Taws Teeb thiab VNC yog ob qho ntawm cov chaw taws teeb nrov tshaj plaws, lawv muaj lawv qhov sib txawv tseem ceeb. Tej thaj chaw deb Desktop tsuas yog muaj nyob rau hauv Windows, thaum VNC muaj nyob rau hauv ntau lub operating systems. Txawm li cas los xij, VNC tsis ceev li tej thaj chaw deb Desktop. Yog tias kev sib txuas hauv Is Taws Nem nrawm txaus, Chaw Taws Teeb Desktop tuaj yeem ceev ceev li siv lub tshuab hauv zos. Vim tias RFB yog pixel raws, VNC tsuas yog xa cov ntaub ntawv nyoos pixels. Tab sis, Tej thaj chaw deb Desktop Protocol muaj peev xwm xa cov duab primitives (thiab nkag siab txog cov duab kos duab zoo dua).

Vim tias qhov sib txawv no, VNC kuj tsis tshua muaj txiaj ntsig dua li Chaw Taws Teeb Desktop, raws li Chaw Taws Teeb Desktop muaj peev xwm ua kom cov ntaub ntawv ntws tau zoo. Tab sis ntawm qhov tod tes, VNC yog qhov hloov tau yooj yim thiab yuav luag txhua hom duab tuaj yeem pom siv VNC. VNC kuj tseem zoo dua rau kev txhawb nqa kev ua haujlwm raws li nws tso cai rau kev sib tham ntawm lub hom phiaj tshuab.
