Detailed explanation-1: -Perfect competition is an ideal type of market structure where all producers and consumers have full and symmetric information and no transaction costs. There are a large number of producers and consumers competing with one another in this kind of environment.

Detailed explanation-2: -A monopoly and an oligopoly are market structures that exist when there is imperfect competition. A monopoly is when a single company produces goods with no close substitute, while an oligopoly is when a small number of relatively large companies produce similar, but slightly different goods.

Detailed explanation-3: -In a monopolistic market, there is only one firm that dictates the price and supply levels of goods and services. A perfectly competitive market is composed of many firms, where no one firm has market control. In the real world, no market is purely monopolistic or perfectly competitive.

Detailed explanation-4: -The most fundamental is perfect competition, in which there are large numbers of identical suppliers and demanders of the same product, buyer and sellers can find one another at no cost, and no barriers prevent new suppliers from entering the market. In perfect competition, no one has the ability to affect prices.
