'Cisco' is one of the biggest technology companies available anywhere, & just like 'Microsoft', is a market leader. It started alongside many others in the I.T. silicon-valley explosion of the 1980's, and has now become the worldwide major networking-hardware manufacturer. Each year Cisco's R and D outlay alone reaches some five billion dollars. The web, it is said, succeeds because of 'Cisco' engineering. It is predicted that above seventy per cent of the entire world-wide network-hardware is represented by the 'Cisco' brand name. For individuals considering working in I.T. or Telecommunications hardware networking, 'Cisco' expertise is essential. The business has also developed commercially in more recent technologies such as Voice Over IP (or VOIP), Security and Wireless-Data transfer.

The question of how to imitate a 'Cisco' 'environment' to prepare for exams can often be overlooked. If you are rehearsing for a MS examination, you're able to assemble a couple of old PC's and you have a real network to learn with. To re-create a Cisco environment though would actually be much more costly, as you'd have to set up many more computers, with commercial technologies & enterprise class routers and data-switches. Cisco-authorised visualisers and network simulation-programs are the one and only workable answer. These deliver an on screen software-system, that lets you essentially develop large scale virtual-networks & test them, down to particular router/data-switch versions, as well as being able to 'interrogate' the packets of data as they navigate the network. These really are outstanding pieces of software, & no home-study or self learning 'CCNA' package should be considered without one. One of the highest quality systems on the market is the RouterSim 'CCNA' Network Visualiser. After assessing this and several others, we're happy to include it in all our Cisco training-paths.

There is a range of certification tracks to go on to after completing the CCNA. Specialized sectors that include 'Security', or Wireless-technology could possibly be selected, or maybe the CCNP (Cisco Certified Networking Professional) which is rather more complex. The 'CCNP' is a rather big step-up from the CCNA, and for most people, contemplating it before you have wholly attained the CCNA isn't to be recommended. Achieve your CCNA and start working on Cisco networks for one or two years before moving on to any 'CCNP' training program. There are some exclusions to this advice, particularly if you've been in IT for a while, and have got alternative accreditation covering much of the same skill-base (military examinations for example.) Essentially companies will want to be sure that an individual with rather advanced qualifications has also had an appropriate amount of working hands-on experience to go with it.

Essentially, the backbone of 'Cisco' technological systems are their routers, data-switches & 'controllers'. Information can flow through any 'network ' because of these Cisco tools. Whilst an Operating System is required on a PC for it to communicate throughout a network, the actual network hardware also has it's own 'language' & protocols that have to be set up, maintained & configured. All networks must efficiently and regularly need to increase, and so on-going maintenance programs mean technicians have to trouble-shoot, reconfigure and re-program on a regular basis. With the present switch towards full system integration of voice & information in today's corporate workplaces (in addition to armed forces & other circumstances), 'Cisco' has found itself at the peak of all contemporary communications.

Little wonder then that a great amount of certification paths have been introduced by 'Cisco' to cover the multitude of technologies & patents it provides. Trainees are usually advised to begin with the same certification program, and then progress into specialised subjects as they progress. And therefore the 'CCNA' - or 'Cisco Certified Network Associate' will equip the right individuals for commercial work with small-medium router and data-switched networks, giving them an understanding of installation, configuration, operation & how to trouble shoot.

The 2 exams are 640-802, and they are divided like this - 'Interconnecting Cisco Networking Devices' Part 1 & Part 2, or 'ICND1' (640/822) and 'ICND2' (640/816). An alternative name for Part-1 is Cisco Certified Entry Networking Technician or 'CCENT' if abbreviated. While all this can seem like a mouth full (as often seems the case with IT acronyms,) the most straightforward way to take this qualification is as a grouped together 'CCNA' (640/802) examination. An outstanding career training track for 'Cisco' students would be a blended package beginning with CompTIA A+ , followed by 'Comptia' Network and then the rather more advanced Cisco 'CCNA'. Expect to put in about 400-500 hrs of study (around a year part time) to complete a track of this nature. As with just about all technical training programs, 24-hour direct access student-support ought to be available to help you to study & ask questions anytime you need to.
