The number of characters that can be moved from an RFID (Radio-Frequency Identification) tag to a reader within a given time: The measure of data transfer rate or the speed with which a computer device transmits information are also used to quantify how fast readers can read the information on the RFID tag.

6. Etymology: the meaning of "time" is from about 1330, from Old French date; from Middle Latin data, noun use of feminine singular of Latin datus, "given" past participle of dare, "to give, to grant, to offer".

The Roman convention of closing every article of correspondence by writing "given" and the day and month, meaning "given to messenger", led to data becoming a term for "the time (and place) stated".

The meaning "to give" is also the root of the grammatical dative (Middle English), the case of "giving".

Dateline in the journalism sense is attested from 1888. The phrase "up to date" (1890) is from bookkeeping. Dated, "old-fashioned", is attested from 1900. Date (noun), "romantic liaison" is from 1885, gradually evolving from the general sense of "appointment"; the verb in this sense is first recorded in 1902.

Information, a fact, a figure, etc. used to make a decision or to come to a result: Data are known or assumed; such as, facts or figures from which a conclusion, or conclusions, can be determined.

Although rarely used properly, if at all, datum should be expressed in the singular sense, for example: "There is one datum on this page that is not correct."

Using the word "fact" instead of datum probably would make one's writing easier to understand and decrease anxiety about the proper use of datum.

Data, as the plural of datum, requires a plural verb in Latin and in English."

People often read; especially, in technical, scientific, and business writings; such usages as, "The data is inconclusive." It should be: "These or Those data are inconclusive."
