Massive in the field of technological know-how, Cisco is now a leader of it's industry sector. First set up in the early 1980's, at the beginning of the silicon-valley IT revolution, Cisco has become the global front-runner within networking hardware, investing some 5 Billion Dollars per annum on research and development. The web, it's said, works because of 'Cisco' engineering. 'Cisco' produce more than 2/3rds of the network-hardware employed around the world these days. For students focused on working in I.T. or 'Telecoms' hardware networking, Cisco know-how is essential. Beneath the 'Cisco' umbrella there are divisions in 'Wi-Fi' and Communications Data, Voice over IP and 'Security'.

Cisco's principal interest is in 'routers', controllers and data switches. These are the equipment which control the information that flows all around a network. Whilst an Operating-System is necessary on a computer for it to communicate throughout a network, the actual network-hardware also has its own 'language' and protocols that must be set up, configured & maintained. For a 'network ' to run smoothly there needs to be on-going trouble-shooting, with frequent re-programming and reconfiguring. In every area of modern day communications, 'Cisco' is performing a key role. This is in no small part because of the shift towards complete system integration of voice and data in both commercial and government places of work.

There are two component elements to the 640-802 'CCNA' certification: The 'ICND1' (640-822), and the ICND2 (640/816). ICND means 'Interconnecting Cisco Networking Devices', although the 'ICND1' exam is also known as CCENT (Cisco Certified Entry Networking Technician). It might appear very baffling, but in reality the accreditation is better when taken as a blended exam - the CCNA 640-802. 'Cisco' students should find it tremendously beneficial to start their training course with the CompTIA accreditations A+ & N+ . That will provide them with outstanding vendor-neutral preparation ahead of entering in to the 'Cisco' domain itself. A combined training-package like this would take approximately a year to complete if training part time. 'Technical' IT training courses should always offer you solid qualified support. You should choose one with 24/7, instant reply provision. Include complete multi-media tutorial training, and an effective exam-preparation system & you will be prepared for great success.

The challenge of exactly how to reproduce a 'Cisco' 'environment' to practise for examinations is frequently overlooked. If you are studying your MS MCSA or MCSE for example, a handful of old Computers can be networked together to allow affordable practice in your own home using genuine equipment. Not so with Cisco - to re-produce any sort of practical environment you'd have to have sophisticated routers & hardware, as well as a large number of PCs & more very high priced technologies. What you need then is to use Cisco approved network simulators & visualisers. These supply an on-screen software-system, that permits you to effectively build large scale 'virtual' networks and test them, right down to precise router and data switch versions, in addition to having the ability to interrogate the packets of information as they traverse the network. A software package such as this is what splits training programs apart - it is unwise to consider any Cisco package that does not include it. We have now included 'RouterSim's' CCNA Network-Visualiser in each of our 'CCNA' career tracks - it's a very highly respected simulator and definitely among the finest we tested.

No surprise then that a considerable variety of qualification paths have been developed by 'Cisco' to handle the multitude of technologies & patents it provides. Trainees are often advised to begin with exactly the same qualification course, and then branch into specialised sectors as they develop. And so the 'CCNA' - or Cisco Certified Network Associate will prepare suitable students for professional work on small-medium router and switched networks, providing them an understanding of how to install, configure, operate and how to trouble-shoot.

To get a particularly well-rounded networking career-path, you may choose to consider adding either the Microsoft MCSE or 'MCSA' to your A+, 'Network+' and 'CCNA' package. With so many possibilities available, a career-track like this should invariably be discussed with an industry expert. That way you can be confident that nothing unsuited to what you want has been bundled in, and nothing is missed.
