Data is the plural of datum. A datum is a statement accepted at face value (a "given"). A large class of practically important statements are measurements or observations of a variable. Such statements may comprise numbers, words, or images.
Etymology
The word data is the plural of Latin datum, neuter past participle of dare, "to give", hence "something given". The past participle of "to give" has been used for millennia, in the sense of a statement accepted at face value; one of the works of Euclid, circa 300 BC, was the Dedomena (in Latin, Data). In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science: data are numbers, words, images, etc., accepted as they stand.
Usage in English
In English, the word datum is still used in the general sense of "something given", and more specifically in cartography, geography, geology, and drafting to mean a reference point, reference line, or reference surface. The Latin plural data is also used as a plural in English, but it is also commonly treated as a mass noun and used in the singular. For example, "This is all the data from the experiment". This usage is inconsistent with the rules of Latin grammar, which would suggest, "These are the data ..."; each measurement or result is a single datum. However, given the variety and irregularity of English plural constructions, there seem to be no grounds for arguing that data is incorrect as a singular mass noun in English. More on [ Data ]
@CRA1G The mobile networks can barely handle all of the 3G data intensive phones that we have now. Battery life would need improvement too.
