What is the difference between industries ltd and company ltd?

Industry:

An industry is a branch of trade that usually includes many companies, such as the Steel Industry and Textile Industry.

Ltd. Company:

A company in which the liability of the members in respect of the company's debts is limited. This is the most common type of registered company. The liability of the members may alternatively be limited by guarantee; in this case the liability of the members is limited by the memorandum to a certain amount which the members undertake to contribute on winding-up. These are usually societies, clubs, or trade associations. It is a popular form of company, because if the company becomes insolvent the winding-up of the company will not bankrupt any of the members.
