Virtual network xam pab txhawb cov chaw taws teeb duab sib koom, ib hom kev nkag mus rau tej thaj chaw deb ntawm lub computer network. VNC qhia txog qhov pom duab pom ntawm lwm lub khoos phis tawj thiab tswj xyuas lub khoos phis tawj ntawm kev sib txuas hauv network. Tej thaj chaw deb desktop thev naus laus zis zoo li VNC khiav thoob plaws lub computer hauv tsev kom nkag mus rau lub computer los ntawm lwm qhov hauv tsev lossis thaum mus ncig. Nws kuj tseem muaj txiaj ntsig zoo rau cov thawj coj hauv network hauv kev lag luam ib puag ncig xws li cov tuam txhab xov xwm thev naus laus zis uas xav tau los daws cov teeb meem hauv thaj chaw deb.

VNC tau tsim los ua qhov kev tshawb fawb qhib rau xyoo 1990s lig. Ob peb lub hauv paus chaw taws teeb desktop daws teeb meem raws li VNC tom qab tshwm sim. Thawj pab pawg tsim kho VNC tsim ib pob hu ua RealVNC. Lwm cov derivatives nrov suav nrog UltraVNC thiab TightVNC. VNC txhawb nqa txhua qhov kev ua haujlwm niaj hnub no.

VNC ua haujlwm li cas

VNC ua haujlwm hauv tus neeg siv khoom / tus qauv thiab siv cov txheej txheem tshwj xeeb hauv network hu ua tej thaj chaw deb ncej tsis. VNC cov neeg siv khoom (qee zaum hu ua cov neeg saib) qhia cov neeg siv nkag-keystrokes, nas txav, nyem, thiab kov-nrog rau cov neeg rau zaub mov.

VNC servers ntes cov khoom hauv cheeb tsam cov ntsiab lus framebuffer thiab muab lawv rov qab rau cov neeg siv khoom, uas tom qab ntawd txhais cov neeg siv khoom nkag mus rau hauv cov tswv yim hauv zos. Kev sib txuas ntawm RFB ib txwm mus rau TCP chaw nres nkoj 5900 ntawm lub server.

Alternatives to VNC

VNC daim ntawv thov, txawm li cas los xij, feem ntau suav tias qeeb dua thiab muab cov yam ntxwv tsawg dua thiab kev xaiv kev nyab xeeb dua li lwm txoj hauv kev tshiab.

Microsoft suav nrog cov chaw taws teeb desktop ua haujlwm rau hauv nws qhov kev khiav haujlwm pib nrog Windows XP. Windows Remote Desktop tso cai rau lub khoos phis tawj Windows kom tau txais kev sib txuas ntawm cov chaw taws teeb los ntawm cov neeg siv khoom sib xws.

Dhau li ntawm cov neeg siv khoom txhawb nqa tsim rau lwm lub Windows li, iOS thiab Android ntsiav tshuaj thiab cov khoom siv smartphone kuj tuaj yeem ua haujlwm raws li Windows Remote Desktop cov neeg siv khoom (tab sis tsis yog servers) siv cov apps muaj.

Tsis zoo li VNC uas siv nws txoj cai RFB, WRD siv cov chaw taws teeb desktop raws tu qauv. RDP tsis ua hauj lwm ncaj qha nrog framebuffers li RFB ua. Hloov chaw, RDP rhuav tshem lub vijtsam duab rau hauv cov lus qhia los tsim cov kab ke thiab xa cov lus qhia tsuas yog hla cov chaw taws teeb sib txuas. Qhov sib txawv ntawm cov txheej txheem ua rau hauv WRD zaug siv tsawg dua lub network bandwidth thiab ua rau muaj kev cuam tshuam ntau dua rau cov neeg siv kev sib cuam tshuam dua li VNC zaug. Qhov ntawd kuj txhais tau tias, txawm li cas los xij, cov neeg siv WRD tsis tuaj yeem pom qhov tseeb ntawm cov khoom siv nyob deb, tab sis hloov yuav tsum ua haujlwm nrog lawv tus kheej cov neeg siv sib cais.

Google tsim Chrome Chaw Taws Teeb Desktop thiab nws tus kheej Chromoting raws tu qauv los txhawb Chrome OS li, zoo ib yam li Windows Chaw Taws Teeb Desktop. Kua txuas ntxiv RFB raws tu qauv nrog ntxiv kev ruaj ntseg thiab usability nta los tsim nws tus kheej Apple Remote Desktop daws rau macOS li. Ib qho app ntawm tib lub npe ua rau iOS pab kiag li lawm ua haujlwm raws li cov neeg siv khoom nyob deb. Cov neeg muag khoom lag luam ywj pheej tau tsim ntau lwm tus neeg thib peb cov chaw taws teeb duab daim ntawv thov ib yam nkaus.
