Much like 'Microsoft', Cisco leads the way as one of the world's largest technology companies. From its humble origins around twenty-six years ago, Cisco today pays around $5b on research and development, and leads the globe in networking-hardware. The web, it's said, functions because of 'Cisco' engineering. 'Cisco' supply more than two-thirds of the network-hardware used in our world right now. For students considering working in I.T. or Telecommunications hardware networking, Cisco knowledge is vital. Within the Cisco umbrella there are also sectors in 'Wi-Fi' and Communications-Data, Voice over IP and Security.

One area that can be often overlooked with studying for 'Cisco' exams is how to reproduce the Cisco environment. Microsoft trainees who are preparing to take their MSCE for instance can network a handful of old computers in their own home to experiment with. This can't be done with Cisco - to re-produce any kind of effective environment you'd need sophisticated routers and data switches, as well as a lot of PC's and further extremely high priced technologies. What you need therefore is to utilise Cisco approved network simulators and visualisers. Such hi tech software systems allow individuals to build large 'networks' in a virtual-environment , using on-screen options to select particular hardware products and practice 'interrogation' of data-movement. These are outstanding pieces of software, and no home study or self learning CCNA course should be considered without one. One of the very best systems available is the 'RouterSim' CCNA Network-Visualiser. After testing this & a number of others, we are happy to feature it in all our 'Cisco' training-paths.

Its hardly a revelation then that Cisco offers many accreditation tracks, covering all of its technologies and it's patents. Students tend to be advised to begin with the same certification course, & then branch into specialist sectors as they develop. Presently there are two exams for the Cisco Certified Network Associate, or CCNA for short. They will furnish students of the right calibre with the required technical expertise to control medium-sized networks with 'routers' and data switches.

To get a particularly broad based combined learning plan you could add MSCA or 'MCSE' from MS to a CompTIA A+/N+ & 'Cisco' CCNA package. In either case, a conversation about your career path and learning-style, with a knowledgeable IT expert or advisor, really should be at the top of your list of priorities, in order to ensure that you will get off to a great start & escape any frustrating blunders.
