This area of I.T. is possibly one of the most sweeping and extensive there is. Generally, some level of specialisation is needed, as to learn about every component could take too many years of studying. Both Cisco and Microsoft make systems for this sector. Microsoft create Network & Server software, whilst Cisco concentrate primarily on the hardware end of Networking: Routers, switches, controllers etc. It has become financially and economically necessary for both Microsoft and Cisco to get into security during the last decade. Also within this field we're experiencing the significant development of wireless-networking. And then we come on to the dark art of Hacking (legally) and Forensics : both complex & very specialist disciplines themselves, and take a great deal of expertise and understanding.

A basic idea of networks is a good first base for anybody coming into the industry. Absolutely nothing else will make sense until you have a grasp of how computers run and connect to each other. Providing you have competent user skills, you'll find the CompTIA A+ & 'Network+' programs are ideal to get you started. Examples of these are dealt with under the CompTIA pages on this site.

What you choose to do next will depend largely upon whether you intend to work in hardware or software. For 'hardware', you are looking at Cisco (CCNA/CCNP), & for software you'll need MS (MCSA or MCSE). Nevertheless, a good understanding of Microsoft's operating systems is extremely advantageous as they are such a vital element of the majority of networking-environments. For more details, you will come across the specifics of each qualification on the actual Cisco and MS areas of the site.

Of course you might want to enhance your 'Wi-Fi' (wire-less) skillsets by taking certifications like the CWNP and CWNA, or continue along the CompTIA route with Linux+, Security+ or Server+ .

Microsoft provide a variety of specialisations within MCSE, such as in Security or Messaging for students with a particular interest. Perhaps, the 'CompTIA' Security+ , advancing on to the CISSP (Certified Information Systems Security Professional) might be suitable. 'CISSP' candidates must have significant professional work experience, so be sure you research this thoroughly. As usual, we suggest a discussion with a skilled IT training advisor in order to avoid any kind of 'mishaps'.

We now have broader options in addition to Microsoft & Cisco when it comes to becoming certified in each of these disciplines. Certainly, quite a few well regarded establishments have become essential contributors now where accreditation is concerned. The importance of grasping converging-technologies and inter connectivity in networks is now solidly recognized. We are experiencing a significant paradigm shift in networking technology today, both in processing terms & in the storage of data, with 'cloud' computing coming to the fore & 'green I.T.' starting to be more and more relevant. From the commercial perspective, greener engineering must be designed to be much more cost effective, as well as being more gentle to the planet. Lower power processors and computers produce much less heat, therefore much less cooling is required. Electricity expenses can often be significantly reduced for businesses like data-centres that are high technology users.

Several of the finest industry-recognised accreditations now come from the vendor neutral 'Computing Technology Industry Association' ('CompTIA'). Some other institutions also offer worthy accreditations, such as CWNP ('Certified Wireless Network Professional') and ISC2 ('International Information Systems Security Certification Consortium'). Clearly, there's a comprehensive variety of accreditation sets from Cisco and Microsoft. With the amount of training & employment options available in this field, it's advisable to get more in-depth help and advice from an industry expert before choosing your specific path. This will keep you from making a costly mistake, both in terms of money & time spent.
