A giant in the particular field of technology, Cisco has become a leader of its industry-sector. Initially set up in the mid 1980's, at the start of the Silicon Valley IT explosion, 'Cisco' is now the global front-runner within networking hardware, investing some five Billion US Dollars a year on R & D. The internet, its said, operates because of Cisco technology. 'Cisco' provide more than 2/3rds of the network hardware used worldwide right now. This automatically puts them at the top of the list for students aiming to build a professional career in IT and Telecoms hardware networking. Cisco additionally has various trading arms that necessarily permeate the Security, VOIP (Voice Over IP) Communications & Wireless-Data (Wi-Fi) fields - as they start to gain growing commercial relevance.

To provide network specialists with all of the knowledge they need to perform in this particular field, Cisco provide a wide range of training courses & accreditations. To help make things simple, candidates are often encouraged to begin their Cisco training courses at the same common stage, prior to developing more advanced & specialist skill-sets. The 'Cisco' CCNA ('Cisco Certified Network Associate') training contains two exams, that will equip a suitable starting candidate with the required skill in installation, configuration, operation, & trouble-shooting of medium sized enterprise level router and switched networks.

Lots of students decide to team up the A+, N+ and CCNA track with either the MS MCSA or MCSE, for a more rounded networking knowledge structure. You should always talk over your training-needs with a knowledgeable industry professional before deciding on your options - not only will it help you save time and expense, it will also double check that you are on the appropriate course from the start.

Moving on from the CCNA, you'll find an array of specialist qualifications to pick from. You may choose to get into wireless technology, or security, or maybe actually on to your 'Cisco Certified Networking Professional' (CCNP). The 'CCNP' is a relatively big step up from the 'CCNA', and for most people, thinking about it before you've fully attained the CCNA isn't advisable. Get your CCNA & start working on 'Cisco' networks for one or two years prior to progressing on to any CCNP study program. The only exemption from this could be when you have a number of years of network experience built up and have covered a lot of the same ground as the 'CCNA' accreditation. In essence, if you are starting up in it, no recruiter will expect you to be at that level of certification, & could rightly question your exact understanding, if you haven't even worked in a 'CCNA' role first.

The 2 examinations are 640-802, & they are broken down as follows - The CCENT (Cisco Certified Entry Networking Technician) examination - also referred to as the ICND1 ('Interconnecting Cisco Networking Devices Part 1' - 640/822) exam, and the ICND2 (640/816) exam. It might appear highly confusing, but basically the qualification is better when taken as a packaged exam - the CCNA 640-802. 'Cisco' trainees will find it extremely useful to begin their training with the 'CompTIA' accreditations A+ and N+ . That will give them outstanding vendor-neutral training prior to getting in to the Cisco arena itself. A combined training package of this nature should take about one year to achieve if training part-time. Much like just about all technical training programs, 24-hour direct access student-support ought to be offered so that you can study & ask questions when-ever the need occurs. The proper studying materials are crucial - look for interactive multimedia disc based programs, and an accredited and highly effective exam preparation system.

'controllers', routers and switches are fundamentally what 'Cisco' technology is founded on. Information can flow through any network because of these Cisco tools. Networking hardware has it's very own set of regulations & procedures. The hardware has to be installed and maintained correctly. Trouble shooting, continual re-programming & reconfiguration is essential to maintain the smooth running of a growing 'network '. 'Cisco' is at the heart of all contemporary office communications (business & government) as we see the international movement towards total voice and information systems-integration.

The question of how to reproduce a Cisco environment to practise for exams can often be over-looked. If you're studying a Microsoft MCSE or MCSA for instance, a couple of old Computers are able to be networked with each other to allow affordable 'dummy-runs' at home using real equipment. This simply isn't possible in a 'Cisco' environment, because you would require enterprise-class routers & data-switches, as well as a substantial number of computers & other extremely expensive technologies. The solution then is to use Cisco approved network simulators and visualisers. Allowing you to practice on-screen, these software systems give you the option to build and test virtual networks. You 'work' with specific routers & switches, and may even interrogate data as it moves through your network system. These really are excellent bits of software, and no home-study or self learning CCNA training program should be considered without one. One of the best software systems available is the RouterSim 'CCNA' Network Visualiser. After assessing this and quite a few others, we are happy to feature it in all our Cisco training-paths.
