Where 194 fits
Why 194 is special
IRC established the shape of group text chat in 1988 — channels prefixed with #, nicknames, operators, bots — and Slack and Discord inherited all of it. The assigned port is 194 but almost every real network used 6667 instead, which is a small lesson in how little registries bind practice.

Roman numerals

CXCIV uses the subtractive pair IV: one before five — five minus one.
Binary
1 1 0 0 0 0 1 0
1 × 128 + 1 × 64 + 0 × 32 + 0 × 16 + 0 × 8 + 0 × 4 + 1 × 2 + 0 × 1 = 194
Octal
3 0 2
3 × 64 + 0 × 8 + 2 × 1 = 194
Hexadecimal
c 2
c × 16 + 2 × 1 = 194
Read as powers of two: 128 + 64 + 2 = 194.
In historical numeral systems
Egyptian
1 coil of rope, 9 hobbles, 4 strokes
1 × 100 + 9 × 10 + 4 × 1 = 194. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 1 corner wedge + 4 vertical wedges (units place)
3 × 60 + 14 = 194. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then koppa, then delta, marked as a numeral
rho-koppa-delta + keraia
rho + koppa + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then tsadi, then dalet
qof-tsadi-dalet
qof (100) + tsadi (90) + dalet (4) = 194, written in descending order.
Maya
1 bar + 4 dots (upper, twenties place) over 2 bars + 4 dots (lower, units place)
9 × 20 + 14 = 194. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

IRC's registered port against the one it actually used. 194 requires privileges and 6667 does not, and practice followed convenience rather than the registry.

Technology & computing
IRC's registered port is 194 and essentially every network ran on 6667 instead, because 194 is privileged and 6667 is not. The protocol's conventions — channels, nicknames, operators, bots — were inherited wholesale by Slack and Discord decades later.

Common questions
Is 194 a prime number?
No, 194 is not prime.
What are the factors of 194?
The factors of 194 are 1, 2, 97, 194.
What is 194 in Roman numerals?
194 in Roman numerals is CXCIV. IV is subtractive: one before five — five minus one. Written additively it would be CLXXXXIIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
