Data and Information

Data [are] values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information.

Data (treated as singular, plural, or as a mass noun) is any sequence of symbols given meaning by specific acts of interpretation.

Information (shortened as info or info.) is that which informs, i.e. that from which data and knowledge can be derived (as data represents values attributed to parameters, while knowledge signifies understanding of real things or abstract concepts).
