Like MS, 'Cisco' leads the way amongst the world's largest technological know-how organisations. It started out alongside many others in the I.T. Silicon Valley explosion of the 1980's, & has now become the world-wide principal networking hardware producer. Each year Cisco's research & development spending on it's own reaches some $5b. Technology from 'Cisco' underpins the whole web. The Cisco branding is thought to be responsible for in excess of 70 percent of all networking hardware. Not surprisingly then, anybody planning to develop a career path to do with networking hardware is advised to consider 'Cisco'. The organisation in addition has grown commercially in more recent technology systems such as Voice Over IP (or VOIP), Security & Wireless-Data transfer.

Lots of trainees elect to partner the 'A+', Network+ & CCNA path with either the Microsoft MCSA or MCSE, for a rather more 'rounded' network education. As there are so many alternatives to select from, a career path of this nature should invariably be talked through with an experienced professional. That way you will be confident that nothing inappropriate for your requirements will be included, and nothing is missed out.

Cisco's main business is in routers, 'controllers' and data switches. Information can move around a network as a result of these Cisco tools. Computers have to have an operating-system to connect up within their network, but in addition to that the hardware has it's own system that has to be set up & maintained. Trouble shooting, continual reprogramming & reconfiguration is necessary to take care of the consistent operating of a growing 'network '. Cisco is in the centre of all contemporary workplace communications (corporate & military) as we watch the global movement towards full voice & information systems-integration.

One area that can be often over-looked when studying for Cisco exams is how to reproduce the Cisco environment. If you are working on the Microsoft MCSA or MCSE for example, some old PC's can be networked with each other to permit inexpensive 'dummy-runs' at home using real equipment. This isn't the case with Cisco - to formulate any sort of practical environment you would have to have complicated routers and data switches, as well as a lot of computers & other extremely costly technologies. Cisco approved 'visualisers' & network simulation-programs are the only practicable answer. Allowing you to practice 'on-screen', these types of software-systems provide the ability to construct and test virtual-networks. You work with particular routers & data switches, and can even 'interrogate' information as it traverses through the network system. Any self-paced home learning 'Cisco' training program must incorporate one of these outstanding items of software. The extremely well respected 'RouterSim's' 'CCNA' Network Visualiser is without doubt among the finest we have tested, and we incorporate it in all our CCNA training courses.

It is not a revelation then that Cisco offers an array of accreditation routes, handling all it's technologies & patents. To make things simple, individuals are generally advised to begin their 'Cisco' training programs at the exact same point, before developing more senior and specialised skill-sets. Presently there are 2 examinations for the 'Cisco Certified Network Associate', or CCNA for short. These will prepare individuals who are suitable with the requested technical know-how to operate mid-level networks with routers & switches.

The CCNA examination (640/802) can be split up into it's two component parts: The 'ICND1' (640-822), and the ICND2 (640/816). 'ICND' is short for Interconnecting Cisco Networking Devices, although the 'ICND1' exam is also called CCENT ('Cisco Certified Entry Networking Technician'). All these abbreviations do nothing at all to clarify matters for the trainee getting in to IT, however the most simple bit of advice is generally to look at the CCNA 640-802 as a blended accreditation. An excellent career training track for Cisco students would be a blended program starting with CompTIA A+ , followed by CompTIA N+ & then the more advanced 'Cisco' 'CCNA'. A bundled training package of this nature should take around a year to complete if training part time. In common with all of the technical career training-programs, be sure to select one that delivers 24 hour real time availability to tutor support, to problem-solve any learning difficulties that occur. The correct study materials are crucial - look for interactive multi-media disc based packages, and an approved & reliable exam practice system.
