Massive within the world of technological know-how, Cisco is now the frontrunner of it's industry-sector. From it's early origins around 26 years back, 'Cisco' now spends around Five billion dollars on R & D, & heads the world in networking hardware. Society basically wouldn't have the world wide web we have today without 'Cisco'. Cisco produce over two-thirds of the network hardware used on earth right now. This inevitably puts Cisco at the top of the list for students planning to make a career in I.T. & Telecoms hardware networking. Under the Cisco 'umbrella' there are divisions in Wireless Data & Communications Data, Voice over Internet Protocol and 'Security'.

One area that can be frequently over-looked when preparing for Cisco examinations is simply how to reproduce the Cisco environment. If you're practicing for a Microsoft exam, it's possible to assemble a couple of old PC's & have a proper networked system to play with. To re-create a Cisco environment would actually be really costly, because you would have to set up a lot more PC's, with Commercial technologies & enterprise-class routers & switches. Cisco-approved 'visualisers' and network simulation-programs are really the one and only practicable way to do it. Enabling you to practice 'on-screen', these types of software-systems provide the ability to construct and test virtual-networks. You work with particular routers and switches, & may even 'interrogate' information as it moves through the network system. These really are superb pieces of software, and no home study or self learning 'CCNA' training program should be considered without one. The highly respected RouterSim's CCNA Network Visualiser is without doubt among the finest we have tried, & we combine this in all of our CCNA training programs.

Fundamentally, the backbone of 'Cisco' technologies are the company's routers, data-switches & 'controllers'. Data can move around a network because of these 'Cisco' tools. PCs require an 'operating system' to connect up inside their 'network ', but in addition to that the hardware has it's own system which needs to be installed and maintained. Networks need to efficiently and frequently have to increase, so on-going maintenance programs mean specialists have to trouble shoot, re-configure and re-program on a regular basis. In every area of modern day communications, Cisco is performing a fundamental role. This is to a large degree because of the move towards complete system integration of voice and information both in commercial and public offices.

There are two component parts to the 640-802 'CCNA' accreditation: Interconnecting Cisco Networking Devices Part-1 & Part-2, or 'ICND1' (640/822) & ICND2 (640-816). An alternate name for Part-1 is Cisco Certified Entry Networking Technician or CCENT for short. Whilst all this may appear to be a mouthful (as can be the case with I.T. acronyms,) the simplest way to take this qualification is as a grouped together CCNA (640/802) examination. This specific track would hugely benefit from being partnered with the CompTIA A+ and N+ accreditations, as they will provide all the necessary 'grounding' prior to having a go at the more advanced 'Cisco specific' examinations. A bundled training package of this nature should take approximately twelve months to complete if studying part-time. As with just about all technical training programs, 24 hour direct-access student support should be offered to let you learn & ask about any queries whenever you want to. Add-in comprehensive multimedia tutorial materials, & a highly effective exam preparation strategy and you will be set for great success.

Following on from your CCNA, there are a wide range of specialized qualifications to pick from. You could get into Wi-Fi, or 'Security', or perhaps even onto the 'Cisco Certified Networking Professional' ('CCNP'). The step from CCNA to the CCNP is quite large, so it is recommended to concentrate on completing the CCNA initially. You would anticipate to be employed in a 'Cisco' environment for at least 12 to 24 months (with your 'CCNA' qualification) prior to getting started to study for the CCNP. If however you have already been in I.T. for a while, and perhaps obtained a qualification that is equivalent to a CCNA (for instance during military service) you may be able to move straight to 'CCNP'. Realistically no employer will contemplate you for any senior post when you haven't got a fair amount of CCNA level working-experience and idea of industry.
