A server component is installed on the remote computer you want to control, while a <a href=\"\/en\/blog\/best-vnc-viewer\/\">VNC viewer<\/a> is installed on the computers or mobile devices you&#8217;ll use to control it.<\/p><p>Once connected, the server transmits the remote computer\u2019s screen to the viewer, adhering to the RFB protocol\u2019s standards, which define how this data exchange is formatted and transmitted.<\/p><p>VNC software allows you to see the remote computer&#8217;s entire screen and control it using keyboard and mouse commands from your device. Mouse movements and keystrokes pass straight to the remote machine, so once permission is granted, the connected user has full control of one computer from another.

Remote desktop is the general category, and VNC is one technology within it. VNC uses the RFB protocol to share the actual screen of the machine you&#8217;re connecting to, so you see exactly what someone sitting at that computer would see.<\/p><p>Microsoft&#8217;s RDP sits in the same category but works differently, typically creating its own session on a server rather than mirroring the physical desktop. Both let you work on a distant machine; they just take different routes to it.<\/p><h3>What is the difference between VNC and VPN?<\/h3><p>They solve different problems, despite the similar acronym. VNC gives you the screen and control of one specific computer, as though you were sitting at it. A VPN doesn&#8217;t show you a screen at all; it puts your device on a private network so you can reach the resources on it.<\/p><p>They&#8217;re often used together rather than instead of each other. A VPN can get you onto the corporate network, and VNC then gives you control of a particular machine on it.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What is VNC?
