What is a Covenant Not To Compete when buying or selling a business

In most business transactions when a business is bought or sold, it is standard to include a Covenant Not To Compete. The logic is simple. The current owner of the business decides they want to sell and a buyer wishes to buy the business. As one of the conditions of buying the business, the buyer stipulates that the seller cannot open the same type of business that the seller currently operates as the buyer is concerned the existing customers will want to do business with the seller rather than transfer their loyalty to the buyer.
