During the early 1980s, there was a married couple namely Len and Sandy Bosack who used to work in two different departments of computer located in Stanford University. This couple was facing problem in making their computers communicate with each other. In order to overcome this problem, they made a gateway server in their living room which led to a simpler way of making two departments communicate each other by the help of IP protocol. They founded cisco Systems (with small c) in 1984, having a small commercial gateway server which brought a revolution in Networking. The name of the company was changed to Cisco Systems, Inc in 1992. Advanced Gateway Server(AGS) was the first marketed product of the company. After this came the Mid-Range Gateway Server(MGS), the Compact Gateway Server(CGS), the Integrated Gateway Server(IGS) and AGS+.
Cisco eventually created routers of 4000, 7000, 2000, and 3000 series. These routers still exist and are enhancing daily. Cisco is the mighty leader of the world when it comes to networking for the Internet. The products of this company leads to simplicity in accessing and transferring information regardless of the differences in time, place or platform.
Cisco also supplies a huge range of hardware products which create information networks by the help of Cisco Internetwork Operating System(IOS) software. Cisco IOS gives network services and make a route for networked technical support and services. Another program made by Cisco to assist the big amount of hardware is the Cisco Certified Internetwork Expert(CCIE) program. CCIE helps in managing the large number of installed Cisco networks. The CCIE program helps in making people take care of complicated networks. Cisco is still monitoring this program constantly in order to do a possible transition needed to meet the everyday requirements of internetworking business places. Due to the very successful CCIE program, you can be certified in network designing and support with the help of Cisco Career Certifications.
