Much like 'Microsoft', Cisco leads the path as one of the world's most significant technology organisations. It started with many more in the IT silicon-valley explosion of the early 80's, & has now become the world's most important networking hardware producer. Every year 'Cisco's' R and D investment alone reaches something like $5 billion. We quite simply wouldn't recognise the web we have right now without 'Cisco'. The Cisco brand is understood to be responsible for in excess of 70 per cent of all networking-hardware. This inevitably places Cisco at the front of the list for trainees seeking to develop a career in I.T. and Telecoms hardware-networking. The organisation also has evolved commercially in newer technology systems such as Voice Over IP (or VOIP), 'Security' and Wireless Data transfer.

The issue of how to simulate a 'Cisco' 'environment' to prepare for exams can often be not addressed. If you are practicing for a MS examination, you can put together a few old PC's & have an actual networked system to learn with. This isn't possible in a 'Cisco' environment, since you would need enterprise-class routers and hardware, to say nothing of a big group of computers & various other extremely expensive technologies. What you need then is to use Cisco authorised network 'simulators' and 'visualisers'. Enabling you to practice on-screen, these software-systems provide the facility to build and test virtual networks. You 'work' with specific routers & data-switches, & may even interrogate data as it traverses through your network system. Any self paced home-based 'Cisco' training course should include one of these extraordinary items of software. The extremely well reputed RouterSim's 'CCNA' Network Visualiser is undoubtedly one of the best we have tested, and we combine it in all of our 'CCNA' training courses.

To equip networking professionals with the information they must have to operate in this field, 'Cisco' offer an array of training programs and accreditations. Generally though, the majority of people will begin at the same point, before they move up-wards through the more and more challenging assortment of 'Cisco' certification. The 'Cisco' CCNA (Cisco Certified Network Associate) training consists of 2 examinations, which will equip an appropriate entrant candidate with the necessary skill in installation, configuration, operation, & trouble-shooting of middle-sized enterprise level router & switched networks.

The 2 exams are 640/802, and they are split up like this - The 'ICND1' (640/822), and the ICND2 (640-816). ICND stands for Interconnecting Cisco Networking Devices, although the ICND1 exam is also known as 'CCENT' ('Cisco Certified Entry Networking Technician'). This can seem very baffling, but in essence the certification is best tackled as a combined examination - the 'CCNA' 640-802. Cisco students will find it very useful to start off their training course with the CompTIA qualifications A+ & N+ . That will give them outstanding vendor neutral preparation prior to getting in to the Cisco domain itself. Anticipate putting in approximately 400-500 hours of study time (approx a year part-time) to get through a course of this nature. In common with all of the technical IT training programs, be sure you choose one that gives 24/7 real time availability to tutor support, to problem-solve any kind of studying challenges that occur. Investigate also for some of the latest multi-media learning materials, and the right exam preparation software.

There is a range of certification tracks to progress on to after finishing your CCNA. Specialist areas that include Security, or Wi-Fi could be looked into, or perhaps the CCNP (Cisco Certified Networking Professional) which is more advanced. It isn't a good idea to consider taking the 'CCNP' until you've fully finished the CCNA. 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 the 'CCNP'. However if you have actually been in the industry for a while, and perhaps obtained a certification of equivalent standing to the 'CCNA' (for instance whilst in the military) you could possibly move straight to CCNP. Essentially business employers will demand that anyone with quite advanced accreditations has also had an appropriate degree of practical experience to go with it.

Essentially, the backbone of Cisco technological systems are the company's 'routers', data-switches and 'controllers'. If we didn't have these systems, information wouldn't be able to pass all around networking systems. Networking hardware has it's very own set of rules & procedures. The 'hardware' needs to be set up & maintained properly. Trouble-shooting, on-going reprogramming & reconfiguration is critical to take care of the consistent running of an expanding network. In all areas of modern day communications, Cisco is playing a key role. This is to a large degree due to the change towards total system-integration of voice and data in both private and government places of work.

To develop a really broad-based combined study program you could add the MCSA or 'MCSE' from Microsoft to the 'CompTIA' A+/Network+ & Cisco CCNA package. As there are so many options to choose from, a career-track of this nature should invariably be discussed with an experienced professional. That way you can be certain that nothing that conflicts with your requirements will be bundled in, & nothing at all has been missed out.
