Kahn and Vinton Cerf created the software - known as the Transmission
Control Protocol/Internet Protocol, or TCP/IP - that allows supercomputers
and desktop PCs to share the Internet.
in Brooklyn, New York, Kahn earned his B.S. in electrical engineering
at the City College of New York before gaining his M.S. and Ph.D.
at Princeton University. While working at the Advanced Research
Project Agency, Kahn designed a system with software and universal
network processors that enabled computers from different locations
to exchange packets of data. Known as the Arpanet, Kahn's initial
discoveries led to long-term problems, forcing him to redesign
his means for encoding data.
turned to Vinton Cerf, a network technician, for help in creating
a standardized data packet, one that would allow data to be easily
transmitted and received over a common network. Their work resulted
in a protocol that exchanged envelopes of data, regardless of
different formatting. Beginning in 1983, TCP/IP became the standard
method to use the Arpanet. This new program allowed the Arpanet
to evolve into the Internet, enabling applications ranging from
e-mail and instant messaging to the World Wide Web.
2004, Kahn received the Turing Award with Cerf for their pioneering
work in computers.
