Racism focuses on accumulated acts of racism across history and throughout one’s lifetime, racism focuses on inter-institutional interactions across time and space, and racism focuses on practices within institutions.

Explanation:

Racism is a discrimination against people of different race, it is based on the belief that one's own race is superior to others.  

It can be expressed consciously or individually through acts, feelings, thoughts or unconsciously through various institutions that promote inequality between races.  

There were many scientific theories about biological differences in races that were prevalent in 19th century, but today scientists have rejected such beliefs. There is no biological basis of race and it is not a scientific concept. Its  the racists  who believe that humans are divided into different races.

Today Racism has two definitions, one is discrimination based on race while the other is discrimination based on culture and religion.
