Much like MS, 'Cisco' leads the path as one of the globe's most well known technology organisations. First launched in 1984, at the start of the Silicon Valley I.T. revolution, Cisco has become the world-wide leader within networking hardware, spending around 5 Billion US Dollars per annum on R & D. Society essentially would not recognise the internet we've got today if it weren't for Cisco. Cisco provide over two thirds of the network hardware employed in our world these days. Unsurprisingly then, any person seeking to develop a career related to networking hardware should focus on 'Cisco'. Cisco also owns a number of trading-arms that automatically permeate the Security, VOIP (Voice Over IP) Communications & Wireless-Data (or Wi-Fi) areas - as they start to gain growing commercial relevance.

There is a range of qualification tracks to progress onto after completing your 'CCNA'. Specialized sectors that include security, or Wireless Technology might be selected, or maybe the CCNP (Cisco Certified Networking Professional) which is rather more complex. The step-up from the CCNA to CCNP is fairly big, so its recommended to concentrate on finishing your 'CCNA' initially. Gain your 'CCNA' & work with 'Cisco' networks for one or two years before progressing onto any kind of 'CCNP' training program. The only exemption would be when you have quite a few years of networking experience already and have dealt with much of the same ground as the CCNA qualification. To be honest, if you're starting up in it, no company will be expecting you to have got to that level of accreditation, and might rightly question your exact understanding, if you've not actually been employed in a 'CCNA' role first.

The right preparation for 'Cisco' exams is a weak thing for many training-providers. Microsoft students who are preparing to take their 'MCSE' for instance can network a number of old computers at home to practice on. To re-create a 'Cisco' environment would be really expensive, because you would need to assemble a lot more PC's, with commercial technologies & 'enterprise-class' routers & switches. Cisco approved visualisers & network simulation-programs are really the one and only practical way to do it. These deliver an on screen software-system, that will let you essentially develop large-scale 'virtual networks' & test them, down to precise router and data switch types, along with being able to 'interrogate' the packets of data whilst they move through the network. These are superb pieces of software, and no home-study or self learning 'CCNA' training program should be considered without one. We have incorporated RouterSim's CCNA Network-Visualiser in each of our CCNA career tracks - it's a very well respected 'simulator' and without any doubt among the finest we tried out.

It's not really surprising then that 'Cisco' has a wide range of qualification paths, covering all of it's various technologies & patents. Typically though, the majority of individuals will commence at one point, before they move on through the more and more detailed myriad of 'Cisco' accreditation. The 'Cisco' 'CCNA' ('Cisco Certified Network Associate') training program contains two examinations, that will prepare a suitable starting candidate with the necessary expertise in the installing, configuring, operating, and trouble-shooting of medium-sized enterprise-level router and switched networks.

The two examinations are 640-802, and they are split up as follows - Interconnecting Cisco Networking Devices Part one and Part two, or 'ICND1' (640-822) and 'ICND2' (640-816). An alternate name for Part-1 is Cisco Certified Entry Networking Technician or 'CCENT' for short. Although all this may appear to be a mouth full (as can be the case with IT acronyms,) the easiest way to do this accreditation is as the grouped together CCNA (640-802) examination. This particular track would greatly benefit from being combined with the 'CompTIA A+' & CompTIA Network+ accreditations, as they provide all of the essential grounding before having a go at the more specialised 'Cisco specific' examinations. You'll want to allow approximately 400 to 500 hrs of study for a combined track such as this. 'Technical' I.T. training courses should provide you with solid qualified support. You should select one with 24/7, immediate response provision. The proper learning materials are vital - look for inter-active multimedia disc based packages, & an approved & highly effective examination prep system.

Essentially, the back-bone of Cisco technological systems are the company's 'routers', data switches and controllers. Information can flow through any network because of these 'Cisco' devices. Computers have to have an operating system to connect up within their network, but in addition to that the actual 'hardware' has its very own 'system' which must be set up & maintained. For a network to operate smoothly there needs to be constant trouble-shooting, with frequent reprogramming and re-configuring. With the shift to complete system-integration of voice & information in modern corporate office buildings (in addition to armed service & other environments), Cisco is at the height of most contemporary communications.

To develop a truly broad-based combined training plan you could include MSCA or MCSE from Microsoft to a 'CompTIA' A+/N+ and 'Cisco' CCNA track. Always speak about your training choices with a knowledgeable IT-training professional prior to deciding on your options - not only will it save you time & money, but it will make sure that you're on the appropriate path from the beginning.
