Like MS, Cisco leads the path amongst the world's most significant technology corporations. From its humble beginnings some twenty-six years ago, Cisco these days spends around five Billion US Dollars on research & development, and heads the globe in networking hardware. Engineering technology from Cisco underpins the whole world wide web. It is thought that above seventy per cent of the entire world-wide network hardware is represented by the 'Cisco' brand. Not surprisingly therefore, any person seeking to build a career path to do with networking-hardware should preferably refer to Cisco. Beneath the 'Cisco' umbrella there also are divisions in Wireless Data & Communications Data, Voice over IP and 'Security'.

Cisco's primary interest is in 'routers', controllers and data-switches. Information can move around a 'network ' as a result of these 'Cisco' solutions. Whilst an Operating System is needed in a computer so that it can connect across a 'network ', the actual network-hardware also has its own 'language' & standards that need to be set up, maintained & configured. Trouble-shooting, continual reprogramming & re-configuration is important to maintain the consistent running of an expanding 'network '. Cisco is in the centre of just about all modern workplace communications (business & government) as we see the global move towards complete voice and data systems-integration.

One thing that's frequently overlooked when studying for Cisco examinations is exactly how to reproduce the Cisco environment. Microsoft students preparing to take their 'MCSE' as an example can 'network' a handful of old PCs in their own home to experiment with. To re-create a Cisco environment would actually be really expensive, because you'd really need to assemble a lot more PCs, with Commercial technologies and 'enterprise-class' routers and switches. Cisco-approved 'visualisers' and network simulation-programs are the one and only sensible way to do it. Enabling you to practice 'on-screen', these types of software systems provide you with the ability to construct and test virtual-networks. You 'work' with specific routers and data-switches, & may even interrogate data as it moves through the network system. These are superb bits of software, and no home-study or self learning CCNA course should be considered without one. The hugely reputed RouterSim's CCNA Network-Visualiser is without doubt one of the most effective we've tried, and we include it in all our CCNA programs.

For a truly broad-based combined learning plan you could include 'MCSA' or 'MCSE' from MS to a 'CompTIA' A+/Network+ and 'Cisco' 'CCNA' track. You should always examine your training-needs with a knowledgeable industry specialist prior to settling on your way forward - not only will it save you time & money, it will ensure that you are on the right course from the beginning.

After the 'CCNA', qualification tracks are quite diverse & may perhaps include a specialisation in Security or Wireless fields, or you might look at progressing to the CCNP (Cisco Certified Networking Professional.) It's not a good idea to consider taking the 'CCNP' unless you have totally completed your CCNA. Achieve the 'CCNA' & start working on 'Cisco' networks for a year or two before moving on to any CCNP training program. The only real exception could be if you have quite a few years of networking practical experience already and have covered much of the very same ground as the CCNA accreditation. Really no employer will think of you for any high level post when you haven't got a reasonable amount of 'CCNA' stage working experience & understanding of networks.

The two exams are 640/802, & they are split up as follows - The ICND1 (640-822), & the 'ICND2' (640-816). ICND stands for 'Interconnecting Cisco Networking Devices', although the ICND1 exam is also called 'CCENT' ('Cisco Certified Entry Networking Technician'). While all this can seem like a mouthful (as can be the case with I.T. abbreviations,) the most straightforward way to take this certification is as a combined 'CCNA' (640/802) examination. This specific track would hugely gain from being combined with the 'CompTIA A+' & 'Network+' accreditations, since they provide all of the important 'grounding' before attempting the more advanced Cisco-specific examinations. Anticipate putting in about four to five hundred hours of study time (around 12 months part time) to finish a course of this type. As with just about all technical training programs, 24 hour direct access student-support needs to be available so that you can learn and ask questions when-ever you want to. Search also for some of the most up-to-date multimedia learning materials, & the best examination practice software.

To equip network professionals with all the knowledge they require to perform in this field, 'Cisco' offer a wide range of training tracks and accreditations. To simplify things, individuals are often encouraged to start their 'Cisco' training programs at the exact same place, prior to building more senior & specialised skill-sets. The 'Cisco' 'CCNA' (Cisco Certified Network Associate) training consists of 2 examinations, which will equip the right entrant applicant with the necessary expertise in the installing, configuring, operating, and trouble shooting of medium sized enterprise-level router & data-switched networks.
