At the school, he hone his talent on the world of technology. He often conduct experiments on computer networks in his school only for hone his talent.

He received a Bachelor of Electrical Engineering and Computer Science degree in 1957 from the City College of New York, and a master’s degree and a doctorate (Ph. D) in Electrical Engineering And Computer Science from the Massachusetts Institute Of Technology in 1959 and 1963 respectively. Then he joined with the Faculty at The University Of California at Los Angeles (UCLA), during 1991-1995 he served as the chairman of the computer science department there.
Leonard Kleinrock have started to find and develop internet since he was in college. Precisely when he is undergoing a master program. He wrote in a paper on the science of computer networks that ultimately the paper became the basic concept of the internet.
In the paper he elaborated on the possibility of the exchange of data between one  device computer to another through a large network that is global. At that time he still had not found the technique, but when he went to UCLA before he managed to find a technical solution digital data packets that can be transmitted through a computer network.
