Networking is not simply an information exchange between you and another person. It involves establishing relationships with people who will often become your friends and community of colleagues as you go through your career. In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hub, bridge, switch, router, and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies and procedures related to the network.
Basically, all we do today through technology happens because of interconnected networks, internal and external, private and public that brings internet connection to our houses every day. Network computer devices that originate, route and terminate the data are called network nodes. Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others but the most known computer network is the Internet.
This video, Cisco’s CEO tells us a little about the company.
And one company that has been around since the beginning of this and providing equipment to connect all of this, is Cisco Networks. Cisco is American multinational technology conglomerate that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technologyservices and products.
Cisco Systems was founded in 1984, and are the guys who build the freeways, roads, the on-ramps, the off-ramps, the traffic lights, and the cops who patrol around these giant network to make sure no one is breaking the rules – they build the hardware and program the software of the internet. From Routers, to Switches, to Security Devices like hardware-based firewalls and intrusion detection systems.
Most of the internet runs on CISCO hardware. Now, thats not all that CISCO does. They also design ‘rules’ and ‘protocols’ in the form of things like EIGRP, to make internet traffic move faster, with greater efficiency and accuracy.
At its core, Cisco designs, builds, and sells networking technology. This hardware is the backbone that makes the Internet work. It’s the modems, switches, routers, and data centers hidden behind the user interfaces of your computer, smartphone, and tablet.
