Where 1042 fits
Why 1042 is special
It specifies the encapsulation that distinguishes Ethernet II framing from 802.2, a difference that caused years of interoperability problems.

Same number, different meanings
How 1042 is understood across different contexts — never implying one meaning because of another.
- Mathematics
It specifies the encapsulation that distinguishes Ethernet II framing from 802.2, a difference that caused years of interoperability problems.
- History
In 1042, Edward the Confessor took the English throne, restoring the West Saxon line (England).
- Technology & computing
RFC 1042 specifies transmission of IP datagrams over IEEE 802 networks using LLC/SNAP encapsulation, coexisting with the earlier Ethernet II framing of RFC 894.

In historical numeral systems
Egyptian
1 lotus, 4 hobbles, 2 strokes
1 × 1,000 + 4 × 10 + 2 × 1 = 1,042. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 7 vertical wedges (sixties place), 2 corner wedges + 2 vertical wedges (units place)
17 × 60 + 22 = 1042. Places are separated by a space on the tablet, with the higher place written first.
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.

Common questions
Is 1042 a prime number?
No, 1042 is not prime.
What are the factors of 1042?
The factors of 1042 are 1, 2, 521, 1042.
What is 1042 in Roman numerals?
