How to say "serial" in Japanese

• シリアルCommon
  prenominal modifierThe katakana loanword; it covers the technical senses of 'serial' — ports, data transmission, and identification numbers on products — rather than a story published in installments.
• 直列ちょくれつCommon
  prenominal modifierThe native word meaning 'in a row, one after another'; in electronics it is the term for components wired in series rather than parallel — not the word for serial ports or numbers.

Use 「シリアル」 for technical senses such as ports, data transmission, and product numbers, and 直列 for things connected or arranged one after another, especially components wired in series in a circuit.
