Like Microsoft, Cisco leads the way amongst the world's biggest engineering technology businesses. It started together with many others in the IT silicon-valley explosion of the 1980's, and is now the worldwide most important networking hardware manufacturer. On a yearly basis Cisco's research & development expenditure alone amounts to approximately five billion dollars. The internet, it is said, functions 'because' of 'Cisco' technology. 'Cisco' produce over two-thirds of the network-hardware employed worldwide today. Unsurprisingly then, any person seeking to develop a career related to networking-hardware is advised to focus on 'Cisco'. Cisco also owns a number of trading arms which automatically permeate the 'Security', VOIP (Voice Over IP) Communications and Wireless-Data (Wi-Fi) sectors - as they gain growing commercial relevance.

For a truly broad based blended training course you could include MSCA or MCSE from Microsoft to a CompTIA A+/N+ and 'Cisco' 'CCNA' package. Always talk over your training needs with an IT-training expert ahead of settling on your way forward - it will not only help you save time and expense, it will double check that you're on the right path from the start.

Essentially, the back-bone of Cisco technological systems are the company's routers, data switches & 'controllers'. These are the equipment that control the information that passes through a networking system. Computers need an operating system to connect up within their network, but in addition to that the actual 'hardware' has it's very own 'system' which has to be set-up and maintained. Trouble-shooting, on-going re-programming & reconfiguration is important to take care of the consistent operating of a growing network. With the shift towards full system integration of voice & data in modern day corporate office buildings (as well as armed forces and other environments), Cisco has found itself at the height of most contemporary communications.

You'll find there are two constituent elements to the 640/802 CCNA qualification: Interconnecting Cisco Networking Devices Pt1 and Pt2, or ICND1 (640/822) and 'ICND2' (640/816). Another name for Part 1 is 'Cisco Certified Entry Networking Technician' or CCENT for short. Each of these acronyms do nothing at all to clarify things for the student getting in to IT, however the most straightforward piece of advice is generally to think about the CCNA 640/802 as a blended accreditation. This specific path would hugely gain from being combined with the 'CompTIA A+' and CompTIA Network+ certifications, as they will provide all of the important 'grounding' before attempting the more advanced 'Cisco specific' exams. Anticipate putting in around 400-500 hours of study (around 12 months part-time) to get through a course of this nature. 'Technical' I.T. training courses should offer you good professional support. Make sure you opt for one with round-the clock, immediate response provision. The right studying materials are vital - look for interactive multi-media disc based packages, and an accredited and effective exam prep system.

Following your 'CCNA', accreditation paths are varied and could very well incorporate a specialisation in Security or Wireless areas, or you might consider moving on to the 'CCNP' (Cisco Certified Networking Professional.) The step up from the CCNA to the 'CCNP' is quite significant, so it is advisable to concentrate on completing your CCNA first. You'd expect to be employed in a 'Cisco' environment for not less than a year or two (with your 'CCNA' qualification) before you started to train for your CCNP. However if you have actually been in the industry for some time, and have previously acquired a certification that compares to a 'CCNA' (for example whilst in the armed forces) you could possibly move directly onto CCNP. Essentially business employers will want to be sure that anyone with rather advanced qualifications has had an appropriate degree of working hands-on experience to go with it.
