Founded in 1979 by Robert Metcalfe, 3COM was a manufacturer of computer modems, network cards, PC cards, servers, hubs, PalmPilots, and other computer components. The company also purchased U.S. Robotics, another popular manufacturer of modems at the time and owner of Palm.
3Com provided network interface controllers and switches, routers, wireless access points and controllers, IP voice systems, and intrusion prevention systems.
On April 12, 2010, Hewlett-Packard completed the acquisition of 3Com. HP integrated 3Com’s network switching, routing and security solutions with its existing HP ProCurve solutions, creating a comprehensive portfolio for customers.
