Cisco is amongst the largest technology companies in the world, and like Microsoft, it's a market leader. It started out with many more in the IT Silicon Valley revolution of the 1980's, and has become the worldwide major networking-hardware manufacturer. Each year 'Cisco's' R & D outlay alone reaches some $5b. Technological know-how from Cisco supports the entire net. The 'Cisco' branding is deemed to be accountable for in excess of 70 percent of all networking-hardware. Not surprisingly therefore, anyone hoping to build a career path related to networking-hardware should preferably take a look at 'Cisco'. The company has also grown commercially in more recent technology systems such as Voice Over IP (or VOIP), 'Security' and Wireless Data transfer.

The two exams are 640-802, & they can be split up like this - The 'ICND1' (640-822), and the 'ICND2' (640-816). 'ICND' means Interconnecting Cisco Networking Devices, but the 'ICND1' exam is often known as CCENT (Cisco Certified Entry Networking Technician). Each of these abbreviations do nothing at all to simplify matters for the individual coming into IT, however the most straightforward bit of advice is generally to think about the 'CCNA' 640-802 as a combined certification. This specific course would hugely gain from being combined with the 'CompTIA A+' & CompTIA Network+ certifications, since they provide all of the important grounding before having a go at the more specialised Cisco-specific exams. A combined training-package such as this would take around a year to do if studying part-time. Technical I.T. training programs should offer you reliable professional support. Be sure to opt for one with round-the clock, immediate response provision. Search also for the latest multimedia study solutions, & the right exam practice software.

No surprise then that a considerable amount of qualification programs have been produced by 'Cisco' to handle the myriad of patents and technologies it produces. Trainees are often encouraged to begin with exactly the same certification program, and then progress into specialised areas as they advance. & so the CCNA - or 'Cisco Certified Network Associate' will equip suitable individuals for commercial work on small to medium router and switched networks, providing them an understanding of how to install, configure, operate and how to trouble-shoot.

In essence, the back-bone of 'Cisco' technologies are their 'routers', switches & controllers. If we didn't have these types of tools, information wouldn't be able to flow around networking systems. Computers need an 'operating system' to connect up within their 'network ', but in addition to that the hardware has it's very own system which needs to be set-up and maintained. Business networks must efficiently and frequently have to expand, so on-going maintenance means technicians need to trouble shoot, reconfigure & re-program on a regular basis. In every area of modern-day communications, 'Cisco' is performing a key role. This is in no small part because of the shift towards total system-integration of voice and information both in private and government workplaces.

The challenge of exactly how to reproduce a 'Cisco' 'environment' to practise for exams can often be over-looked. MS students who are preparing to take their MSCE as an example can network a number of old PC's in their own home to experiment with. This isn't feasible in a Cisco environment, as you would need enterprise-class routers & data-switches, as well as a big number of PC's and various other very costly technologies. The answer therefore is to utilise Cisco-approved network simulators and visualisers. Enabling you to practice on-screen, these software systems provide you with 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. A software program of this standard is exactly what splits training courses apart - it is not wise to consider any 'Cisco' package that does not incorporate it. The highly reputed 'RouterSim's' 'CCNA' Network-Visualiser is without doubt one of the best we've tested, and we combine it in all our 'CCNA' programs.
