Cisco calls itself "The Worldwide Leader in Networking for the Internet" [1] (http://newsroom.cisco.com/dlls/company_overview.html).
In 2003, Cisco acquired Linksys, a popular manufacturer of computer networking hardware and positioned the Linksys brand it as a network-hardware brand for the home and the end user installed SOHO network market. The Cisco brand is positioned to service the managed remote access, teleworker access, security services, storage area networking, desktop and data center routing and switching, the commercial market IP communication needs as well as the enterprise and service provider infrastructure and remote access market.
Using acqusitions, internal development and partnering with other companies Cisco has made inroads in the IP telephony part of the voice market with the Cisco IP phones, call managers and telephony PSTN gateways. Cisco earlier made inroads in the ATM market through its 1996 acquisition of StrataCom Inc.
The married couple Leonard Bosack and Sandra Lerner, who worked in computer operations staff at Stanford University, founded Cisco Systems in 1984. Bosack adapted multiple protocol router software originally written by William Yeager, another staff employee who had begun the work years before Bosack arrived from the University of Pennsylvania, where Bosack had received his Bachelor's degree.
While Cisco was not the first company to develop and sell a router -- a device that forwards computer traffic from one network to another -- it did create the first commercially successful multi-protocol router. This is a device that allows previously incompatible computers to communicate, even though they use different network protocols.
In 1990 Bosack and Lerner walked away with $170 million after the firm's venture capitalists brought in professional managers [2] (http://www.forbes.com/forbes/1997/0825/6004058a.html). Bosack and Lerner later divorced.
Cisco has set up "Cisco Networking Academies" in 128 countries aimed at teaching students to design and maintain computer networks.
Cisco provides certifications to professionals in the networking field. These include:
- CCIE (Cisco Certified Internetwork Expert)
- CCNA (Cisco Certified Network Associate)
- CCDA (Cisco Certified Design Associate)
- CCNP (Cisco Certified Network Professional)
- CCDP (Cisco Certified Design Professional)
- CCIP (Cisco Certified Internetwork Professional)
- CCSP (Cisco Certified Security Professional)
The company has its corporate headquarters in San Jose, California.
John Chambers is the current President and CEO.
History of the Cisco name The name "Cisco" is not an acronym, but an abbreviation of San Francisco. In the early days, when the founders proposed names, they repeatedly came up with names already reserved or in use. Eventually someone suggested "cisco", with a lowercase "c". (Another company named "CISCO" already existed at that time.) The name ciscoSystems (with the lowercase "c") continued in use within the engineering community at the company long after the official company name was changed to Cisco Systems, Inc. You can still see the name ciscoSystems occasionally in bug reports and IOS messages.
The company's logo reflects its San Francisco name heritage: it represents a stylized Golden Gate Bridge.
