A giant within the world of technological solutions, Cisco has become the leader of its industry-sector. Initially set up in 1984, early on in the silicon-valley I.T. revolution, Cisco has grown to be the world-wide frontrunner within networking hardware, spending some 5 Billion dollars each year on research & development. The internet, it's said, succeeds 'because' of Cisco engineering. It's predicted that more than seventy per cent of the entire world-wide network-hardware is represented by the 'Cisco' brand name. Not surprisingly then, anyone looking to develop a career path to do with networking-hardware should preferably refer to 'Cisco'. 'Cisco' also has various trading-arms which automatically permeate the Security, VOIP (Voice Over IP) Communications and Wireless Data (Wi-Fi) areas - as they gain more commercial importance.

Fundamentally, the back-bone of Cisco technologies are the company's 'routers', switches and controllers. They are the tools that facilitate the data that passes through a networking system. Networking hardware has its very own set of regulations & procedures. The hardware needs to be installed & configured properly. Trouble-shooting, continual reprogramming & reconfiguration is necessary to keep up the smooth operating of an expanding 'network '. In all areas of modern day communications, 'Cisco' is enjoying a fundamental role. This is to a large degree because of the change towards complete system-integration of voice and data both in private and public places of work.

To provide networking professionals with the information they require to operate in this discipline, Cisco offer a large number of training routes and accreditations. Students are usually advised to start with the same accreditation course, and then move into specialist areas as they advance. The Cisco CCNA (Cisco Certified Network Associate) training program contains two examinations, that will equip a suitable entrant candidate with the important skill in installation, configuration, operation, & trouble shooting of middle-sized enterprise-level router and switched networks.

One thing that can be often overlooked when preparing for 'Cisco' examinations is how to simulate the 'Cisco' environment. MS trainees who are preparing for their MSCE for instance can 'network' a few old PCs in their own home to experiment with. To build a practise 'Cisco' environment though would actually be extremely expensive, because you'd really need to assemble a lot more computers, with Commercial technologies and 'enterprise-class' routers & switches. The solution then is to use Cisco-approved network simulators and visualisers. Such hi tech software systems allow individuals to create large networks within a 'virtual environment' , with on screen facilities to pick specific hardware products & practice 'interrogation' of data movement. These really are superb pieces of software, & no home study or self learning 'CCNA' package should be considered without one. One of the very best software systems out there is the RouterSim 'CCNA' Network-Visualiser. Upon trying out this and a number of others, we are proud to incorporate it in all our Cisco training paths.

To develop a really broad based blended study program you could include the MCSA or MCSE from MS to a 'CompTIA' A+/Network+ and Cisco CCNA package. As there are so many opportunities available, a career track of this sort should always be discussed with an IT expert. This way you will be confident that nothing unsuited to your requirements will be added, & nothing at all is missed.
