‘Diànnǎo’ literally means ‘electric brain’ — combining 电 (diàn), meaning ‘electricity’ or ‘electrical’, and 脑 (nǎo), meaning ‘brain’. This vivid compound reflects how computers function like an artificial brain: processing information, storing data, and executing tasks based on instructions. It’s the standard, neutral term for ‘computer’ in modern Mandarin and is used across all contexts — from casual conversation to formal documents.

The word is highly productive and appears in many compound terms, such as 电脑桌 (diànnǎo zhuō, ‘computer desk’) and 电脑病毒 (diànnǎo bìngdú, ‘computer virus’). Unlike older terms like 计算机 (jìsuànjī, also meaning ‘computer’ but more technical or academic), 电脑 is universally understood and preferred in everyday speech, especially when referring to personal desktops, laptops, or general computing devices.
