802
IEEE 802 is the family of standards behind Ethernet and Wi-Fi.

Where 802 fits
Why 802 is special
802.3 is Ethernet, 802.11 is Wi-Fi and 802.1X is network authentication. Practically every wired and wireless local network in the world runs on a member of this one numbered family, which is why the prefix appears on equipment nobody thinks of as standardised.

Binary
1 1 0 0 1 0 0 0 1 0
1 × 512 + 1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 0 × 16 + 0 × 8 + 0 × 4 + 1 × 2 + 0 × 1 = 802
Octal
1 4 4 2
1 × 512 + 4 × 64 + 4 × 8 + 2 × 1 = 802
Hexadecimal
3 2 2
3 × 256 + 2 × 16 + 2 × 1 = 802
Read as powers of two: 512 + 256 + 32 + 2 = 802.
In historical numeral systems
Egyptian
8 coils of rope, 2 strokes
8 × 100 + 2 × 1 = 802. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 3 vertical wedges (sixties place), 2 corner wedges + 2 vertical wedges (units place)
13 × 60 + 22 = 802. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
omega, then beta, marked as a numeral
omega-beta + keraia
omega + beta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then tav, then bet
tav-tav-bet
tav (400) + tav (400) + bet (2) = 802, written in descending order.
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.

IEEE 802 labels the local area network family, and its sub-numbers identify Ethernet and Wi-Fi individually.
The IEEE local area network standards are adopted internationally under an ISO/IEC number for procurement purposes.
