Information

Information (shortened as info) is that which informs. In other words, it is the answer to a question of some kind. It is also that from which data and knowledge can be derived, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

At its most fundamental, information is any propagation of cause and effect within a system. Information is conveyed either as the content of a message or through direct or indirect observation of some thing. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.

Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a sequence of signals). It can also be encrypted for safe storage and communication.

Celebrity

Celebrity is fame and public attention in the media, usually applied to a person, or group of people (celebrity couple, family etc.), or occasionally, to animals or fictional entities. Celebrity status is often associated with wealth (commonly referred to as fame and fortune) and fame can often provide opportunities to make money.

Successful careers in sports and entertainment are commonly associated with celebrity status; political leaders often become celebrities. People may also become celebrities due to media attention for their lifestyle, wealth, or controversial actions, or for their connection to a famous person.

History

Throughout recorded history there are accounts of people who attracted the trappings of celebrity which would be recognized today.

Athletes in Ancient Greece were welcomed home as heroes, had songs and poems written in their honour and received free food and gifts from those seeking celebrity endorsement.Ancient Rome similarly lauded actors and notorious gladiators and Julius Caesar appeared on a coin in his own lifetime (a departure from the usual depiction of battles and divine lineage).
