Ari VPN-kubatana sei?

Pfungwa chaivo private network, rakapfupikiswa sezvo VPN (kubva Chirungu Virtual Private Network), akaonekwa zvemichina kombiyuta achiri ichangopfuura. Kuti pave akwirwe kwakadai akabvumira chokubatanidza kombiyuta zviteshi uye Mobile rakapotsa samambure pasina zvatinosiita waya, zvisinei kubva nzvimbo zvimwe inouraya. Zvino funga mubvunzo kuti VPN-kubatana, uye panguva imwecheteyo kupa vamwe mazano rakamiswa network dzakadaro uye akabatanidza yeGmail.END_STRONG software.

Chii chinonzi VPN?

Sezvo zviri pachena, VPN ndiye rakapotsa private samambure multiple namano chokuita nazvo. Ko kuzvinyengera - kubatanidza vaviri kana vatatu zviteshi dhazeni pamunhu yaizoshanda panguva kombiyuta (zvinogona kuitwa sezvo vari "lokalke") kazhinji hakushandi. Ine painogumira mu pomumbure configuration, kana kunyange vanokwanisa pakati router riri basa rakavapa IP-kero uye mashoko chinja.

Zvisinei, pfungwa pakutanga vakaradzikwa nezvichaitika zvemichina hakusi chitsva. Akaedza kupembedza refu. Uye vazhinji vanoshandisa kombiyuta network vanhasi Pari hatina pfungwa chii vaiziva nezvazvo zvose hwangu, asi chete haina edza pokupedzisira nyaya.

Sei VPN-kubatana: dzinokosha uye michina

Nokuti nokunzwisisa tinopa muenzaniso nyore chaizvo, rinozikamwa munhu ano. Ibva pane redhiyo. Pashure pezvose, Chokwadi, chinhu emitting chikwata (mushanduri), kuti Mediation unit (repeater) anokonzera kupararira uye kuparadzirwa anonongedzera uye kugamuchirwa mudziyo (mugamuchiri).

Chimwe chinhu ndechokuti chiratidzo iri inoparadzirwa zvachose vatengi zvose, uye rakapotsa rezvebonde akasarudzwa, kuunganidzwa pomumbure mumwe, chete zvimwe namano. Ona kuti kunyange yekutanga kana nyaya yechipiri, tambo nokuti unobva achitumira uye kugamuchira mano kuchinjana mashoko nemumwe, havadikanwi.
