Cisco is one of the largest technology-companies on earth, and like 'Microsoft', is a market-leader. From it's humble beginnings around 26 years ago, Cisco these days pays in the region of five Billion US Dollars on research and development, and heads everybody in networking hardware. The web, it's said, succeeds 'because' of Cisco engineering. The Cisco branding is considered responsible for above seventy percent of all networking-hardware. This inevitably puts them at the top of the checklist for students aiming to make a professional career in IT & Telecommunications hardware networking. The business has also evolved commercially in more recent technologies such as VOIP, 'Security' & Wireless-Data transfer.

For a specifically well rounded network career-track, you could look at adding the Microsoft 'MCSE' or MCSA to your 'A+', 'Network+' and 'CCNA' package. Always talk about your training-needs with an industry professional prior to deciding on your way forward - not only will it help you save time and expense, but it will also ensure that you are on the appropriate track from the start.

Effective preparation for 'Cisco' examinations is often a weak area with many training providers. If you are studying the Microsoft 'MCSA' or 'MCSE' for example, a couple of old PC's can be networked together to allow inexpensive 'dummy-runs' in your own home using genuine devices. This can't be done with Cisco - to create any sort of effective environment you'd have to have complicated routers & data switches, in addition to a lot of PCs & further very expensive technology. The solution therefore is to utilise Cisco authorised network simulators & visualisers. Allowing you to practice 'on-screen', these software-systems give you the option to build & test virtual-networks. You practice with specific routers and data-switches, & may even 'interrogate' data as it moves through your network system. These really are outstanding pieces of software, and no home-study or self-learning CCNA course should be without one. The extremely well respected RouterSim's CCNA Network-Visualiser is undoubtedly among the best we have tried, and we include it in all our 'CCNA' training courses.

Its hardly surprising then that 'Cisco' offers an array of qualification paths, dealing with all of its various technologies and patents. Trainees are generally encouraged to begin with exactly the same certification course, and then branch into specialised elements as they develop. There are two examinations in the Cisco Certified Network Associate, or 'CCNA' for short. They will furnish students who are suitable with the necessary technical know-how to control medium-sized networks with routers and switches.

Moving on from the CCNA, you'll find many specialist certifications out there. You could potentially go into Wi-Fi, or Security, or perhaps even onto the Cisco Certified Networking Professional ('CCNP'). The step-up from the 'CCNA' to CCNP is rather large, so it is advisable to concentrate on finishing the CCNA initially. You need to get 2 yrs of Cisco experience together with the 'CCNA' before progressing on to the 'CCNP' accreditation. The only real exception would be if you have a number of years of network practical experience built up and have covered a lot of the very same ground as the 'CCNA' qualification. Essentially recruiters have to know that anyone with quite advanced qualifications has also had a suitable amount of practical experience to match.

The 'CCNA' exam (640-802) can be broken down in to it's 2 constituent parts: 'Interconnecting Cisco Networking Devices' Part one and Part two, or ICND1 (640-822) and ICND2 (640/816). An alternative name for Part 1 is Cisco Certified Entry Networking Technician or 'CCENT' for short. Each of these acronyms do nothing to simplify matters for the trainee coming into IT, however the most simple bit of advice is generally to think about the CCNA 640/802 as a blended qualification. An outstanding career training-track for Cisco students would be a blended package beginning with 'CompTIA A+' , followed by 'Comptia' 'Network+' and then the more advanced Cisco 'CCNA'. Count on putting in around 400-500 hours of study time (around 12 months part-time) to get through a program of this nature. In common with all technical IT training-programs, make sure you decide on one that provides 24/7 real time access to tutor assistance, to 'problem-solve' any training issues that arise. Investigate also for the most up-to-date multi-media learning materials, & the right examination practice software.

'controllers', 'routers' & switches are essentially what 'Cisco' technology is based on. They're the tools that control the information that flows all around a network. Whilst an 'Operating System' is needed in a computer for it to communicate across a network, the network-hardware itself has it's own 'language' & standards that must be set-up, configured & maintained. All networks need to efficiently and regularly need to expand, consequently on-going maintenance means specialists need to trouble-shoot, re-configure & reprogram on a regular basis. Cisco is at the heart of just about all present day workplace communications (business & government) as we see the global movement towards complete voice & data systems integration.
