Not unlike MS, Cisco leads the path as one of the world's largest engineering technology organisations. It began alongside many others in the IT silicon-valley explosion of the 1980's, and is now the world's major networking-hardware developer. Each and every year 'Cisco's' R & D investment alone comes to some $5 billion. Technological know-how from 'Cisco' underpins the entire net. It's estimated that above 70 percent of all global network-hardware is under the 'Cisco' brand name. This instantly puts Cisco at the top of the list for trainees aiming to build a professional career in I.T. and 'Telecoms' hardware networking. The company also has developed commercially in newer technology systems such as VOIP, 'Security' & Wireless-Data transfer.

The challenge of exactly how to simulate a 'Cisco' 'environment' to practise for exams can often be not addressed. If you're rehearsing for a Microsoft examination, you can assemble a couple of old PC's and you have a proper network to experiment with. This is not do-able in a 'Cisco' environment, because you would require enterprise-class routers & data switches, as well as a large cluster of PCs & other extremely costly technologies. The solution therefore is to use Cisco approved network 'simulators' and 'visualisers'. Enabling you to practice 'on-screen', these types of software systems provide you with the option to build & test virtual-networks. You 'work' with specific routers and switches, and can even 'interrogate' information as it moves through your network. Any self-paced home based 'Cisco' training course should incorporate one of these extraordinary pieces of software. The highly respected 'RouterSim's' CCNA Network Visualiser is without doubt among the finest we've tried, & we combine this in all of our CCNA training programs.

Following the CCNA, certification paths are quite varied & could incorporate a specialization in Security or Wireless areas, alternatively you could look at moving on to the 'CCNP' ('Cisco Certified Networking Professional'.) The step up from the 'CCNA' to 'CCNP' is pretty big, so its advisable to concentrate on finishing your CCNA initially. Achieve the 'CCNA' and start working on Cisco networks for a year or two ahead of progressing onto any 'CCNP' training program. Really the only exception could be when you have quite a few years of networking experience built up & have dealt with much of the same ground as the 'CCNA' certification. Realistically no recruiter will contemplate you for any higher-level role when you haven't got a reasonable degree of 'CCNA' grade working-experience & knowledge of industry.

In essence, the backbone of 'Cisco' technologies are the company's routers, data switches & 'controllers'. They're the tools which control the data that passes through a network. Just as an 'Operating System' is required in a PC so that it can connect across a network, the actual network-hardware also has it's own language and protocols that need to be set-up, maintained and configured. Business networks must run smoothly & often have to grow, therefore on-going maintenance means specialists must trouble-shoot, reconfigure and reprogram regularly. With the present move to full system-integration of voice and information in modern corporate workplaces (not forgetting armed service and other circumstances), Cisco is at the peak of most modern communications.
