Much like 'Microsoft', Cisco leads the path amongst the world's most well known technology corporations. From it's early origins around twenty-six years ago, Cisco today invests something like $5 billion on research and development, & heads everybody in networking hardware. Technological know-how from Cisco supports the entire world wide web. Cisco supply more than two-thirds of the network-hardware employed worldwide today. This inevitably puts Cisco at the front of the list for students aiming to build a professional career in I.T. & Telecommunications hardware networking. The organisation has additionally grown commercially in more recent technologies like VOIP, 'Security' & Wireless-Data transfer.

It is not really surprising then that 'Cisco' provides a wide range of accreditation routes, handling all of it's technologies and it's patents. Trainees are usually recommended to start with exactly the same certification course, & then branch into specialised subjects as they progress. There are two exams in the 'Cisco Certified Network Associate', or CCNA for short. These will furnish individuals of the right calibre with the necessary technical expertise to operate medium-sized networks with 'routers' & switches.

'Cisco's' principal interest is in 'routers', controllers and data-switches. Data can flow through any network because of these 'Cisco' solutions. Just as an Operating-System is necessary in a computer so that it can communicate across a network, the network-hardware itself has its own language and protocols that must be set up, maintained & configured. For a 'network ' to run smoothly there must be constant trouble shooting, with regular reprogramming & re-configuring. With the present move towards complete system-integration of voice & data in modern corporate workplaces (in addition to armed service & other environments), 'Cisco' is at the pinnacle of most modern communications.

The dilemma of exactly how to reproduce a 'Cisco' 'environment' to practise for examinations can often be overlooked. When you are working on your Microsoft 'MSCE' or 'MCSA' as an example, some old PC's can be 'networked' with each other to permit economical practice at home with real devices. This isn't do-able in a Cisco environment, as you'd require enterprise-class routers & data switches, to say nothing of a substantial group of PC's & various other highly expensive technologies. Cisco-authorised 'visualisers' and network simulation programs are the one and only acceptable way to do it. These deliver an on screen software-system, that enables you to effectively construct large-scale 'virtual networks' and test them, right down to precise router and data switch types, in addition to being able to interrogate the packets of data as they navigate the network. These are excellent bits of software, and no home-study or self-learning CCNA course should be considered without one. The very well reputed 'RouterSim's' CCNA Network Visualiser is without doubt one of the best we have tried, and we combine it in all of our 'CCNA' training programs.
