What's the difference between a public sector business and a public limited company?

The business world is divided into the public sector and private sector.

Public sector businesses are run by the government and often provide necessities like electricity or bus services. The private sector is run by individuals or groups of individuals.

Within the private sector, there are sole traders, partnerships, private limited companies and public limitied companies. We can discuss the other parts of the private sector in our session, but for now, a public limited company is one that has limited liability and can sell shares to the public to gain more capital.
