Like 'Microsoft', 'Cisco' champions the way as one of the globe's largest engineering technology companies. It began with many more in the IT silicon-valley revolution of the 1980's, & has now become the world's major networking-hardware producer. Each year 'Cisco's' research & development outlay alone reaches approximately $5 billion. Society essentially wouldn't recognise the web we've got today without 'Cisco'. The Cisco branding is considered responsible for in excess of seventy per cent of all networking-hardware. Not surprisingly then, any person looking to develop a career path related to networking hardware is advised to take a look at Cisco. The organisation in addition has evolved commercially in new technologies like Voice-Over IP (VOIP), Security & Wireless Data transfer.

Many trainees choose to blend the 'A+', N+ and 'CCNA' path with either the Microsoft 'MCSA' or 'MCSE', to get a rather more rounded networking knowledge structure. In either case, a conversation about your career path and learning style, with a knowledgeable IT expert or consultant, must be at the front of your sheet of priorities, to be sure you will get off to a really good start and escape any expensive errors.

The question of exactly how to imitate a 'Cisco' environment to prepare for examinations is frequently over-looked. When you are studying the MS MCSA or MCSE as an example, a couple of old PC's can be networked with each other to allow inexpensive practice at home with genuine devices. Not so with Cisco - to create any kind of useful environment you would have to have complex routers & data switches, as well as many computers & more extremely high priced technologies. Really the only practical answer is to utilise simulated networks that have been approved by Cisco. Such hi tech software systems enable trainees to build large 'networks' within a virtual-environment , using on-screen facilities to pick particular hardware products & practise 'interrogation' of data movement. Any self paced home-based Cisco training course must incorporate one of these extraordinary items of software. We have now incorporated RouterSim's CCNA Network-Visualiser in our 'CCNA' career-tracks - this is a very highly respected simulator & certainly one of the highest quality products we tested.

The CCNA exam (640/802) can be broken down in to its two constituent parts: The ICND1 (640-822), and the 'ICND2' (640/816). 'ICND' stands for 'Interconnecting Cisco Networking Devices', however the 'ICND1' exam is often known as 'CCENT' (Cisco Certified Entry Networking Technician). This can appear very confusing, yet in reality the qualification is better when taken as a blended exam - the 'CCNA' 640-802. An excellent career training-track for Cisco entrants would be a blended program starting with CompTIA A+ , then 'Comptia' 'Network+' and then the rather more specialised 'Cisco' CCNA. Expect to put in approximately four to five hundred hrs of study time (around 1 year part time) to complete a course of this type. 'Technical' IT training programs should offer sound professional support. You should choose one with round-the clock, instant reply service. The correct studying materials are vital - look for inter-active multi-media disc-based packages, and an approved and highly effective examination preparation system.

To provide network experts with all of the information they require to work in this discipline, 'Cisco' provide a large number of training programs & accreditations. Trainees are often recommended to begin with the same qualification course, & then progress into specialist subjects as they develop. & so the 'CCNA' - or Cisco Certified Network Associate will prepare the right trainees for professional work on small-medium router & data-switched networks, providing them an understanding of how to install, configure, operate & how to trouble-shoot.

Following on from the 'CCNA', there are an array of specialist certifications to choose from. You could potentially go into wireless technology, or Security, or perhaps even on to your 'Cisco Certified Networking Professional' ('CCNP'). It isn't advisable to consider doing the 'CCNP' before you've totally finished your 'CCNA'. You should get two years of Cisco experience along with your 'CCNA' ahead of moving onto 'CCNP' accreditation. If however you have already been in IT for a while, & have previously obtained a qualification that compares to a 'CCNA' (for instance whilst in the armed forces) you might possibly move directly onto CCNP. The bottom line is that if you're starting in it, no boss will expect you to have got to such a high level of accreditation, and might rightly query your exact understanding, if you haven't actually worked in a CCNA role first.

Controllers, routers and data switches are fundamentally what Cisco technology is founded on. If we didn't have these types of systems, data would be unable to move around networking systems. PC's need an operating-system to connect up inside their network, but in addition the actual hardware has it's very own 'system' which must be installed & maintained. For a 'network ' to run smoothly there needs to be constant trouble-shooting, with frequent re-programming and reconfiguring. With the switch towards full system-integration of voice & information in today's business workplaces (in addition to armed forces and other circumstances), Cisco is at the pinnacle of all contemporary communications.
