There are a lot of people who may be aware of what private and public means. When you say private, this can be a sector that is owned by someone in particular. A private business is something that is controlled by certain individuals.
A public sector, on the other hand, is something that may be owned by different public enterprises. There are also times when the public sector is owned by the government. There are just some particular sectors that will manage this.
For private and public also, there are some private beaches which means that the beach can be exclusive to those who own the property. A public beach, on the other hand, is a place wherein almost everyone can go as long as they have the means to get there.
