This area of I.T. is possibly one of the most sweeping & extensive there is. Normally, some degree of specialisation is needed, as to learn about every element could take decades of learning. The main systems contributors in this marketplace are Cisco and Microsoft. MS create Network & Server Software, whilst Cisco focus primarily on the hard-ware end of networking: Routers, switches, controllers etc. Each of the corporations have moved seriously into Security during the last decade, by commercial necessity. Also in this field we are witnessing the substantial development of wireless-networking. And then we have Hacking (legitimately) & Digital Forensics : both very complex and extremely specialised subjects themselves, & take a great deal of working experience and knowledge.

Microsoft produce various MCSE specialism's, for instance in Messaging or Security for students who have a particular interest. It might be that CompTIA Security+ is right for you, so you can move on to the CISSP - 'Certified Information Systems Security Professional'. 'CISSP' prospects must have significant professional experience, therefore be sure you research this well. As usual, we recommend talking with an experienced IT training advisor to avoid any 'mishaps'.

A basic knowledge of networks is an ideal first-base for anybody getting into the industry. You must know exactly how computers function and communicate with one another before you can do anything else. Providing you have effective user-skills, you'll find the 'CompTIA' A+ & CompTIA Network+ training programs are ideal to begin with. These are dealt with within the 'CompTIA' section of this site.

Moving on from this level is often the domain of the MS MCSA or MCSE or the Cisco 'CCNA'/'CCNP', subject to whether you are interested in the hardware or software end of things. Although, it must be mentioned that a good understanding of MS network systems is basically a necessity for most network environments, simply because of Microsoft's dominance in this field. For more details, you'll come across information regarding each qualification on the actual Cisco & Microsoft sections of the web site.

Equally of course you could fine tune your Wi-Fi (wire-less) skills by taking qualifications such as the 'CWNA' and 'CWNP', or carry on along the CompTIA path with Server+, Security+ or Linux+ .

'CompTIA' (the Computing Technology Industry Association) is a worldwide company that currently offers a number of the most highly regarded vendor-neutral accreditation paths available. Organisations like ISC2 supply security qualifications, and 'CWNP' provide specialist wireless-networking tracks. Most conspicuously of course are Cisco & Microsoft themselves, each providing their very own qualification tracks. Mainly because of the scope and amount of accreditation tracks available in this sector, it's a good idea to talk through this sort of career move with an experienced advisor. This will likely prevent you from making an expensive mistake, in terms of time & money spent.

We now have wider alternatives over and above Cisco & Microsoft for getting accredited within each of these sectors. A number of well respected independents are today providing progressively more appropriate and important accreditations. The need for understanding converging-technologies and inter-connectivity in networks has become very well accepted. We are experiencing a significant paradigm shift within networking technologies today, thoughts generally are inclined towards 'greener' I.T., & both processing power & data-storage are switching towards Cloud computing. The development of 'green' IT addresses two essential factors : reducing the impact to the earth is one, but possibly of equal significance to industry is cost. The actual processing-power in more technologically advanced computer systems is lower, which means less heat to be cooled down. These two things together vastly cut down the energy bill, & so affect a corporation's bottom-line -- primarily in data centres & high-volume processing departments.
