5900
Port 5900 carries VNC, a protocol for viewing and controlling another machine's screen.

Where 5900 fits
Why 5900 is special
VNC transmits the screen itself rather than commands, so it works with any operating system and is slow over long links. Its password field is limited to eight characters, which is why an exposed 5900 is one of the most reliably compromised ports on the internet.

Read as powers of two: 4,096 + 1,024 + 512 + 256 + 8 + 4 = 5,900.
In historical numeral systems

5 lotuses, 9 coils of rope
5 × 1,000 + 9 × 100 = 5,900. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
VNC and RDP both provide remote control of a desktop. VNC sends the screen image and works anywhere; RDP sends drawing commands and is faster but tied to Windows.

VNC sends the screen image rather than commands, so it works across operating systems. Its authentication is limited to an eight-character password, which combined with frequent exposure makes 5900 one of the most reliably compromised ports on the internet.
