Massive in the particular field of technological solutions, Cisco has become a leader of it's industry sector. It started alongside many others in the IT silicon-valley explosion of the 1980's, & has become the world's major networking-hardware manufacturer. Each year 'Cisco's' R & D expenditure on it's own reaches some $5 billion. We in essence would not recognise the internet we have today without Cisco. Cisco produce more than two thirds of the network-hardware employed worldwide today. This automatically places them at the top of the checklist for individuals planning to build a career in IT & Telecoms hardware-networking. The business also has developed commercially in more recent technologies like Voice Over IP (or VOIP), Security and Wireless-Data transfer.

Cisco's principal business is in 'routers', 'controllers' & data switches. They're the devices that control the information that passes through a network. Just as an Operating-System is required in a PC so that it can communicate across a 'network ', the actual network-hardware also has its own 'language' & standards that have to be set-up, configured and maintained. Trouble shooting, on-going reprogramming & reconfiguration is important to maintain the consistent running of an expanding network. In every area of modern day communications, Cisco is playing a fundamental role. This is to a large degree because of the shift towards total system-integration of voice and information both in private and public office buildings.

One area which is frequently overlooked with preparing for 'Cisco' examinations is exactly how to reproduce the Cisco environment. When you're practicing for a MS examination, you're able to assemble some old Computers & have a real network to learn with. This isn't the case with Cisco - to formulate any kind of beneficial environment you'd have to have complicated routers & hardware, as well as many computers and other really costly technologies. Cisco authorised 'visualisers' & network simulation programs are the only practicable option. Enabling you to practice 'on-screen', these software systems provide the facility to build and test virtual-networks. You 'work' with specific routers & switches, and can even interrogate information as it travels through the network. A software package of this standard is exactly what splits training programs apart - it's not wise to think about any 'Cisco' package which doesn't encompass it. Among the most sought after systems available is the 'RouterSim' CCNA Network-Visualiser. After trying out this and quite a few others, we are happy to incorporate it in our 'Cisco' training paths.

The 'CCNA' examination (640/802) is split in to its 2 constituent parts: The CCENT (Cisco Certified Entry Networking Technician) examination - also called the ICND1 ('Interconnecting Cisco Networking Devices Part 1' - 640/822) exam, and the ICND2 (640-816) exam. This might seem very confusing, but in essence the certification is best taken as a packaged examination - the 'CCNA' 640/802. An excellent career training-track for Cisco students would be a blended package starting with 'CompTIA A+' , then 'Comptia' Network & then the more advanced Cisco 'CCNA'. You'll want to give yourself approximately 400-500 hours of study-time for a combined program like this. Technical IT training courses should provide solid qualified support. Be sure you choose one with round-the-clock, instant reply service. Add in all-inclusive multimedia tutorial materials, & a powerful exam preparation system & you will be set for great success.

A lot of trainees choose to partner the 'A+', N+ & CCNA track with the MS MCSA or MCSE, to get a rather more rounded network education. Whatever your thoughts, a conversation about your career path & learning style, with a skilled IT expert or consultant, must be at the head of your sheet of priorities, to be sure that you will get off to a really good start and avert any costly errors.

Moving on from the CCNA, you'll find an array of specialized qualifications out there. You could possibly go into Wi-Fi, or security, or maybe even on to your Cisco Certified Networking Professional ('CCNP'). It isn't a good idea to consider taking the CCNP before you have fully completed the 'CCNA'. Attain the 'CCNA' & get a job with 'Cisco' networks for a year or two before progressing onto any kind of CCNP training program. There are actually some exceptions to this, mainly if you have worked in IT for quite some time, & have alternative accreditation that covered a lot of identical skill-base (armed forces exams as an example.) The bottom line is that if you are starting in it, no boss will be expecting you to have got to such a high level of accreditation, and might rightly query your real understanding, if you haven't even been employed in a CCNA role first.
