When a string is spoken aloud, B/P/D/T can sound alike. The assigns a fixed word to each letter — a shared standard for aviation, the military and IT.
The alphabet
- A Alfa · B Bravo · C Charlie · D Delta · E Echo · F Foxtrot · G Golf · H Hotel · I India
- J Juliett · K Kilo · L Lima · M Mike · N November · O Oscar · P Papa · Q Quebec · R Romeo
- S Sierra · T Tango · U Uniform · V Victor · W Whiskey · X X-ray · Y Yankee · Z Zulu
- 9 is pronounced Niner and 5 may be pronounced Fife to improve intelligibility in international radio communication.
In IT this is communication hygiene: FG01 is spoken as Foxtrot-Golf-Zero-One, removing ambiguity between O and 0.
Practice
- Say a lab hostname three times in under ten seconds.
- In pairs, read six-character strings until you complete ten without an error.
- FG01-ADMIN: Foxtrot-Golf-Zero-One, dash, Alfa-Delta-Mike-India-November.
Risks and mitigation
- An identifier error can lock an account, send work to the wrong machine or waste time during an incident.
- Keep the chart by your screen and use the standard for hostnames, serials and licenses.
