'Cisco' is one of the most significant technology-companies in the world, & like 'Microsoft', is a market leader. First started in the mid 1980's, at the start of the silicon-valley I.T. revolution, 'Cisco' has grown to be the global front-runner within networking-hardware, spending approximately five Billion Dollars a year on R & D. Technology from 'Cisco' underpins the whole web. It is predicted that more than seventy per cent of the entire worldwide network hardware is represented by the 'Cisco' brand. Unsurprisingly therefore, anybody hoping to develop a career related to networking-hardware should preferably take a look at 'Cisco'. Beneath the 'Cisco' 'umbrella' there are also sectors in 'Wi-Fi' & Communications-Data, Voice over IP and 'Security'.

Following the CCNA, qualification paths are quite diverse & could possibly incorporate a specialisation in Wireless or Security fields, or you could look at moving to the CCNP ('Cisco Certified Networking Professional'.) It isn't recommended to contemplate doing the 'CCNP' unless you've fully completed the CCNA. It's best to get a couple of years of Cisco experience alongside your CCNA ahead of moving onto the 'CCNP' certification. There are actually certain exclusions to this, particularly if you've been in IT for some time, and have got equivalent accreditation covering a lot of identical information (armed forces exams for example.) In reality a recruiter won't consider you for a high level job when you haven't got a fair amount of CCNA level working-experience and idea of networks.

Cisco's primary business is in 'routers', controllers and data-switches. Data can flow through any 'network ' because of these 'Cisco' tools. Networking hardware has it's own set of regulations & procedures. The hardware has to be installed and maintained the right way. For a 'network ' to run smoothly there has to be constant trouble-shooting, with regular reprogramming and reconfiguring. In all areas of modern-day communications, Cisco is playing a fundamental role. This is to a large degree due to the change towards complete system-integration of voice and data both in commercial & public office buildings.

To equip networking professionals with all of the knowledge they require to perform in this field, 'Cisco' provide a wide range of training tracks and certifications. Students are often advised to start with exactly the same certification program, & then move into specialist elements as they advance. Presently there are 2 examinations for the 'Cisco Certified Network Associate', or 'CCNA' for short. These will prepare individuals of the right calibre with the recommended technical-expertise to operate mid-level networks with routers and data switches.
