The traditional caste system in India was a system in which the people were divided in several castes, and they were not able to change their caste during their life. A caste represented a social status, so in what caste a person is born in that caste that person spends its life.
The members of the same caste were interacting with each other. They collaborated, visited each other, married between each other. They also used the same public places, lived in similar facilities, and were pretty much on the same level in most aspects of life.
When it came to members of different castes, than they were not communicating with one another except if they had to. Marriages between members of different castes were forbidden. Also, it was humiliating and shameful to interact with people from lower castes, so we can easily say it was an example of segregation in the society.
