Paul Baran (born April 29, 1926) was one of the three inventors of packet-switched networks, along with Donald Davies and Leonard Kleinrock. Paul A Baran (1910 - 1964 was an American economist known for his Marxist views Events 1429 - Joan of Arc arrives to relieve the Siege of Orleans. Year 1926 ( MCMXXVI) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar. Packet switching is a network communications method that splits data traffic (digital representations of text sound or video data into chunks called packets, that are then Donald Watts Davies, CBE FRS ( June 7, 1924 &ndash May 28, 2000) was a Welsh Computer scientist Leonard Kleinrock PhD (born June 13, 1934 in New York) is a Computer scientist, and a professor of computer science at UCLA He was born in Grodno[1] (then Poland), but his family moved to Boston in 1928. Poland (Polska officially the Republic of Poland Year 1928 ( MCMXXVIII) was a Leap year starting on Sunday (link will display full calendar of the Gregorian calendar. Baran did undergraduate work at Drexel University, obtained his Masters degree in Engineering from UCLA in 1959 and began working for the RAND Corporation in the same year. Drexel University is a private Coeducational University located in Philadelphia, Pennsylvania, United States.

The development of a communication network that would withstand a nuclear attack was important to US defence strategy. A telecommunications network is a network of Telecommunications links and nodes arranged so that messages may be passed from one part of the network to another over The United States of America —commonly referred to as the Baran developed his ideas for a distributed network as a solution to the problem of maintaining Command and Control of military resources in the event of a nuclear attack.
Similar ideas for a distributed data network were being independently pursued by Donald Davies from the National Physical Laboratory in the UK, although Davies was primarily concerned with the problem of resource-sharing rather than Baran's focus on military issues. The National Physical Laboratory (NPL is the national Measurement standards laboratory for the United Kingdom, based at Bushy Park in Teddington The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located
Baran also provided a spark of invention to four other important networking technologies. He was involved in the origin of the packet voice technology developed by StrataCom at its predecessor, Packet Technologies. StrataCom, Inc was founded in Cupertino, California USA in January 1986 by 26 former Employees of the failing Packet Technologies, Inc This technology led to the first commercial pre-standard ATM product. In electronic digital data transmission systems the Network protocol Asynchronous Transfer Mode (ATM encodes data traffic into small fixed-sized cells He was also involved with the discrete multitone modem technology developed by Telebit, which was one of the roots of Orthogonal frequency-division multiplexing which is used in DSL modems. Modem (from mo dulator- dem odulator is a device that modulates an analog carrier signal to encode Digital information Telebit was a US -based Modem manufacturer most notable for their TrailBlazer series of high-speed modems Orthogonal frequency-division multiplexing ( OFDM) — essentially identical to Coded OFDM ( COFDM) and Discrete multi-tone modulation ( Paul founded Metricom, the first wireless Internet company, which deployed Ricochet, the first public wireless mesh networking system. Ricochet Networks was one of the pioneering wireless Internet service providers in the United States, before the advent of widespread Wi-Fi, 3G He also founded Com21, an early cable modem company. In all cases, he provided early ideas and gave credibility to strong groups of developers who then took those ideas far beyond Baran's original spark.
Paul Baran also extended his work in packet switching to wireless-spectrum theory, developing what he called "kindergarten rules" for the use of wireless spectrum.
In addition to his innovation in networking products, he is also credited with inventing the metal detector used in airports. Metal detectors use Electromagnetic induction to detect Metal.
