Information can be thought of as the resolution of uncertainty; it is that which answers the question of "what an entity is" and thus defines both its essence and nature of its characteristics. It is associated with data, as data represents values attributed to parameters, and information is data in context and with meaning attached. Information relates also to knowledge, as knowledge signifies understanding of an abstract or concrete concept.In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. 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 signal). It can also be encrypted for safe storage and communication. The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that. The more uncertain an event, the more information is required to resolve uncertainty of that event. The bit is a typical unit of information, but other units such as the nat may be used. For example, the information encoded in one "fair" coin flip is log2(2/1) = 1 bit, and in two fair coin flips is log2(4/1) = 2 bits. The concept of information has different meanings in different contexts. Thus the concept becomes related to notions of constraint, communication, control, data, form, education, knowledge, meaning, understanding, mental stimuli, pattern, perception, representation, and entropy.
A government is the system or group of people governing an organized community, often a state.In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. Each government has a kind of constitution, a statement of its governing principles and philosophy. Typically the philosophy chosen is some balance between the principle of individual freedom and the idea of absolute state authority (tyranny). While all types of organizations have governance, the word government is often used more specifically to refer to the approximately 200 independent national governments on Earth, as well as subsidiary organizations.Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy and tyranny. The main aspect of any philosophy of government is how political power is obtained, with the two main forms being electoral contest and hereditary succession. Libertarianism and anarchism are political ideologies that seeks to limit or abolish government, finding government disruptive to self organization and freedom.
A welcome is a kind of greeting designed to introduce a person to a new place or situation, and to make them feel at ease. The term can similarly be used to describe the feeling of being accepted on the part of the new person. In some contexts, a welcome is extended to a stranger to an area or a household. "The concept of welcoming the stranger means intentionally building into the interaction those factors that make others feel that they belong, that they matter, and that you want to get to know them". It is also noted, however, that "[i]n many community settings, being welcoming is viewed as in conflict with ensuring safety. Thus, welcoming becomes somewhat self-limited: 'We will be welcoming unless you do something unsafe'". Different cultures have their own traditional forms of welcome, and a variety of different practices can go into an effort to welcome: Making a welcome is not a physical fabrication, though welcome may be embodied and fostered by appropriate physical arrangements. There can be an aesthetics of welcome. What is there when one makes a welcome? No thing really, and yet more than any thing. When one makes a welcome one creates the conditions that promise of home. One makes it possible for the other not any longer to feel outside or out of it, but to feel at home. Indications that visitors are welcome can occur at different levels. For example, a welcome sign, at the national, state, or municipal level, is a road sign at the border of a region that introduces or welcomes visitors to the region. A welcome sign might also be present for a specific community, or an individual building. One architect suggests that "[a] primary distinction between a gateway and a Welcome sign is that the gateway is usually designed and built by an outsider, a developer or architect, while the Welcome sign has been designed and built by an inside member of the community". A welcome mat is a doormat that welcomes visitors to a house or other building by providing them with a place to wipe their feet before entering. Another community tradition, the welcome wagon, a phrase that originally referred to an actual wagon containing a collection of useful gifts collected from residents of an area to welcome new people moving to that area.
