Command economies are organized by rules, and those rules are decided upon by a centralized authority. For example, the government decides what goods will be produced and how much will be made. It is impersonal, in that individuals in the society probably don't know the individuals in the government who make the decisions. Market economy is one in which decisions about production and distribution are made mostly by individuals and companies in the economy. People do things because they see the potential for benefits, such as choosing a job with the salary that allows you to live the lifestyle you want.
Companies produce goods based on what they think they can sell.
Market economies are organized around free exchange. In the real world, there is no such thing as a pure market economy, or a pure command economy.
