A buzzword is a word or phrase, new or already existing, that becomes popular for a period of time. Buzzwords often derive from technical terms yet often have much of the original technical meaning removed through fashionable use, being simply used to impress others. Some buzzwords retain their true technical meaning when used in the correct contexts, for example artificial intelligence. Buzzwords often originate in jargon, acronyms, or neologisms. Examples of overworked business buzzwords include synergy, vertical, dynamic, cyber and strategy.

Big data primarily refers to data sets that are too large or complex to be dealt with by traditional data-processing application software. Data with many entries (rows) offer greater statistical power, while data with higher complexity may lead to a higher false discovery rate. Though used sometimes loosely partly due to a lack of formal definition, the best interpretation is that it is a large body of information that cannot be comprehended when used in small amounts only.
