Business
Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.

Hospitality
Hospitality refers to the relationship between a guest and a host, wherein the host receives the guest with goodwill, including the reception and entertainment of guests, visitors, or strangers. Louis, chevalier de Jaucourt describes hospitality in the Encyclopédie as the virtue of a great soul that cares for the whole universe through the ties of humanity.

International mostly means something (a company, language, or organization) involving more than a single country. The term international as a word means involvement of, interaction between or encompassing more than one nation, or generally beyond national boundaries. For example, international law, which is applied by more than one country and usually everywhere on Earth, and international language which is a language spoken by residents of more than one country.
Tourism
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveller's country. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes".

Business Administration
The administrative function comes easily to conservatives for the principal requirement of administration is unquestioning conformity to the standards embodied by the particular institution.

Tourism
I sat on a toilet watching the water run thinking what an odd thing tourism is. You fly off to a strange land, eagerly abandoning all the comforts of home and then expend vast quantities of time and money in a largely futile effort to recapture the comforts you wouldn’t have lost if you hadn’t left home in the first place.
