Null

/nʌl/

अमान्य; शून्य/रिक्त; अस्तित्वहीन (विशेषकर कंप्यूटिंग में ‘नल’ मान)

Origin & History

From Latin nullus (“none, not any”), from ne (“not”) + ullus (“any”).

लैटिन nullus (“कोई नहीं/एक भी नहीं”) से; ne (“नहीं”) + ullus (“कोई/कुछ”) से बना।

Definition

“Null” describes something that is invalid, has no effect, or does not exist; as a noun it can mean an empty/non-existent value, especially in computing and databases (a missing/unknown value, not the same as zero).

“Null” का अर्थ है कोई चीज़ जो अमान्य हो, जिसका कोई प्रभाव न हो, या जो अस्तित्व में न हो; संज्ञा के रूप में यह विशेषकर कंप्यूटिंग/डेटाबेस में रिक्त/ग़ैर-मौजूद मान को दर्शाता है (यह ‘0/शून्य’ से अलग है—यह ‘अनुपस्थित/अज्ञात’ मान हो सकता है)।
