Much like MS, Cisco leads the path as one of the globe's most well known technological know-how corporations. From it's early inception around twenty-six years ago, Cisco now spends around five Billion US Dollars on research & development, & heads the world in networking-hardware. We basically would not recognise the world wide web we've got today if it weren't for Cisco. The Cisco branding is deemed to be responsible for over 70 per cent of all networking hardware. This instantly puts Cisco at the front of the checklist for trainees aiming to make a career in IT & 'Telecoms' hardware-networking. Under the Cisco 'umbrella' there are divisions in Wireless Data & Communications-Data, VOIP and 'Security'.

It is hardly surprising then that Cisco offers a wide range of certification routes, dealing with all it's technologies and patents. Students tend to be advised to start with the same certification program, and then branch into specialist sectors as they progress. And therefore the CCNA - or Cisco Certified Network Associate will prepare suitable trainees for professional work on small-medium router & data-switched networks, providing them an understanding of installation, configuration, operation and how to trouble-shoot.

The 2 examinations are 640-802, & they can be broken down as follows - The 'CCENT' ('Cisco Certified Entry Networking Technician') exam - also called the ICND1 (Interconnecting Cisco Networking Devices Part 1 - 640/822) exam, and the 'ICND2' (640/816) exam. While all of this can look like a mouthful (as often seems the case with IT abbreviations,) the easiest way to take this accreditation is as a grouped together 'CCNA' (640-802) exam. 'Cisco' trainees will find it particularly beneficial to start their training with the 'CompTIA' certifications A+ and Network+ . That will provide them with extremely good vendor-neutral preparation prior to getting into the 'Cisco' field itself. It's best to give yourself about 400 - 500 hours of study-time for a blended program like this. As with just about all technical study programs, 24/7 direct-access student support should be accessible to let you study & ask questions whenever the need occurs. Check also for some of the latest multimedia study materials, and the right examination practice software.

'Cisco's' principal business is in routers, 'controllers' & switches. If we didn't have these types of systems, information would be unable to 'flow' around networks. Computers need an operating system to connect up within their network, but also the actual hardware has its own 'system' which must be set up and maintained. For a network to operate efficiently there has to be on-going trouble shooting, with regular reprogramming and reconfiguring. In all areas of modern-day communications, 'Cisco' is enjoying a key part. This is to a large degree because of the change towards complete system-integration of voice and data both in commercial & government offices.

For a very broad-based blended learning plan you could include 'MCSA' or 'MCSE' from Microsoft to the CompTIA A+/Network+ & 'Cisco' CCNA package. Whatever your thoughts, a conversation about your career path & learning style, with a skilled industry expert or consultant, should be at the head of your list of priorities, in order to make sure that you get off to a great start & prevent any costly errors.
