noun
Technical term used in computing, settings, and configuration contexts to refer to a preset value that is used when no alternative is specified.
この設定の既定値は「オフ」です。
The default value for this setting is 'off'.
ユーザーが何も入力しなければ、既定値が使われます。
If the user enters nothing, the default value will be used.
Often translated as 'initial value', which is the value set at the start of a process or program. 既定値 emphasizes a preset standard, while 初期値 focuses on the starting state.
Compound of 既定 (きてい, 'established, predetermined') and 値 (ち, 'value'). The word follows standard Sino-Japanese word formation patterns.
