Not unlike Microsoft, Cisco champions the way as one of the globe's biggest engineering technology corporations. Originally founded in 1984, at the beginning of the Silicon Valley IT revolution, Cisco is now the global leader in networking-hardware, investing around five Billion dollars a year on research and development. We quite simply would not recognise the web we have today without Cisco. Cisco provide more than 2/3rds of the network-hardware employed on earth these days. This automatically places them at the front of the checklist for students looking to build a career in I.T. & Telecommunications hardware networking. Under the 'Cisco' 'umbrella' there are also sectors in Wireless Data and Communications-Data, Voice over Internet Protocol and Security.

There are a number of certification paths to move on to after completing the 'CCNA'. Specialised sectors including security, or Wireless-technology might be considered, or maybe the CCNP (Cisco Certified Networking Professional) which is more advanced. The step up from the CCNA to the CCNP is rather significant, so it's a good idea to concentrate on finishing the 'CCNA' initially. You'd expect to be working in a Cisco environment for about 12 to 24 months (together with your 'CCNA' qualification) prior to getting started to study for your CCNP. If however you've actually been in I.T. for quite a while, and have already obtained a accreditation that compares to the 'CCNA' (e.g. whilst in the military) you may be able to go straight to CCNP. Essentially companies need to know that an individual with very senior accreditations has also had a suitable degree of practical hands-on experience to match them.

'controllers', routers and data-switches are mainly what 'Cisco' engineering technology is based on. These are the tools that control the data that flows around a networking system. Networking-hardware has it's very own set of rules & procedures. The hardware needs to be set up and maintained correctly. Trouble shooting, continual reprogramming & reconfiguration is essential to take care of the consistent operating of an expanding 'network '. With the switch towards complete system integration of voice & information in today's corporate workplaces (as well as military and other environments), Cisco is at the height of all contemporary communications.

Little wonder then that a great number of qualification programs have been developed by Cisco to deal with the multitude of technologies and patents it provides. Students are generally advised to begin with exactly the same accreditation program, and then progress into specialised areas as they advance. The Cisco 'CCNA' (Cisco Certified Network Associate) program consists of 2 exams, that will prepare an appropriate starting candidate with the essential expertise in the installing, configuring, operating, & trouble-shooting of middle-sized enterprise level router and data-switched networks.
