Not unlike Microsoft, 'Cisco' champions the way amongst the world's most significant technology organisations. It began with many more in the IT silicon-valley explosion of the early 80's, and is now the worldwide most important networking-hardware producer. Each year Cisco's R and D spending alone reaches something like $5b. Society essentially wouldn't recognise the web we've got today if it weren't for Cisco. It is thought that above seventy per cent of all world-wide network hardware is represented by the 'Cisco' brand name. This automatically places Cisco at the front of the checklist for individuals aiming to build a career in IT and Telecommunications hardware-networking. Under the 'Cisco' 'umbrella' there also are divisions in Wireless Data & Communications Data, VOIP & 'Security'.

Small wonder then that a substantial amount of certification programs have been designed by Cisco to cover the multitude of technologies and patents it supplies. To make things simple, individuals are likely to be encouraged to begin their 'Cisco' training courses at the same common place, before acquiring more complex and specialist skillsets. There are 2 examinations in the 'Cisco Certified Network Associate', or 'CCNA' for short. These will furnish students of the right calibre with the requested technical expertise to operate mid-level networks with routers and data-switches.

Fundamentally, the backbone of Cisco technological systems are their routers, data-switches and 'controllers'. Without these systems, data would be unable to move all around networking systems. Whilst an 'Operating System' is required in a PC so that it can connect across a network, the actual network hardware also has it's own language and protocols that have to be set up, maintained and configured. Trouble shooting, on-going re-programming and re-configuration is critical to take care of the effortless running of a growing 'network '. 'Cisco' is at the heart of just about all current workplace communications (business & government) as we observe the worldwide movement towards full voice and information systems-integration.

For a really broad based blended study system you could include 'MCSA' or 'MCSE' from Microsoft to your CompTIA A+/Network+ and Cisco CCNA track. Either way, a conversation about your career path and learning-style, with a skilled IT specialist or advisor, must be at the top of your list of priorities, in order to be sure that you get off to a great start and avoid any expensive errors.

One thing which is often overlooked when studying for Cisco exams is exactly how to simulate the Cisco environment. When you are studying your MS MCSA or MCSE for instance, a couple of old PC's are able to be 'networked' together to allow economical practice in your own home with real devices. This isn't feasible in a Cisco environment, as you would require enterprise-class routers and data switches, as well as a big number of PCs and various other highly expensive technologies. The only workable solution is to utilise simulated networks that are authorised by Cisco. Enabling you to practice 'on-screen', these software-systems give you the option to build and test virtual networks. You 'work' with specific routers & data switches, & can even 'interrogate' information as it moves through your network. A software package such as this is what sets training programs apart - it is not wise to decide upon any Cisco package that doesn't incorporate it. We have incorporated RouterSim's CCNA Network-Visualiser in our 'CCNA' career-tracks - it's a very highly respected simulator and undoubtedly one of the best we examined.

The CCNA examination (640/802) is split up in to it's two constituent parts: The 'ICND1' (640-822), & the 'ICND2' (640/816). ICND means Interconnecting Cisco Networking Devices, however the 'ICND1' exam is also referred to as 'CCENT' ('Cisco Certified Entry Networking Technician'). While all this can look like a mouth full (as often seems the case with I.T. acronyms,) the simplest way to do this qualification is as a combined 'CCNA' (640/802) exam. This specific track would greatly gain from being partnered with the CompTIA A+ & 'Network+' certifications, since they provide all the necessary grounding prior to having a go at the more advanced Cisco-specific examinations. Expect to put in about 400 to 500 hours of study time (around 12 months part time) to finish a program of this nature. In accordance with all of the 'technical' IT training courses, ensure you select one that delivers twenty four hour real time access to tutor support, to problem-solve any learning challenges that occur. The correct learning materials are vital - go for inter-active multi-media disc-based products, & an accredited and highly effective examination practice system.

Following on from CCNA, there are a wide range of specialist accreditations out there. You could potentially get into wireless technology, or 'Security', or maybe even on to your Cisco Certified Networking Professional ('CCNP'). It's not a good idea to contemplate taking the CCNP until you've totally accomplished your CCNA. You'll want to have a couple of years of Cisco experience alongside your 'CCNA' prior to moving on to the 'CCNP' certification. If however you have actually been in the industry for a while, and perhaps gained a qualification of equivalent standing to a 'CCNA' (for example during military service) you may be able to move directly onto 'CCNP'. Really a recruiter won't think about you for a higher-level post when you haven't got a reasonable degree of CCNA grade working experience and knowledge of industry.
