This area of IT is possibly just about the most sweeping and comprehensive there is. It would take far too long to become a professional in all aspects, and so specialisation is essential to some extent. Cisco and Microsoft are the 2 significant vendors ruling this sector. Microsoft produce Network & Server software, whilst Cisco focus largely on the hard-ware end of networking: Routers, switches, controllers etc. Both corporations have moved seriously in to security over the last several years, through economic need. We should likewise notice the the greater commercial use of WiFi today, which is basically wireless connections and hard-ware. And next we come on to the dark art of Hacking (legitimately) & Computer Forensics - each complex & incredibly specialised disciplines themselves, & take a great deal of expertise and knowledge.

The vendor neutral worldwide institution 'CompTIA' now delivers perhaps the most recognised and widely-respected independent IT certifications. Establishments such as 'ISC2' provide 'Security' qualifications, and 'CWNP' offer specialist wireless-networking tracks. Of course, there is a whole gamut of accreditation sets from Cisco and Microsoft. The options may well be somewhat over-whelming, & so we advise you to tread cautiously & talk through your options with an advisor who knows the procedure very well. You might save yourself a lot of money and time, as well as aggravation and disappointment.

If you are planning to build a career in IT, start by picking up a certain amount of networking expertise. Until you're confident about how a PC functions and 'communicates' with other PCs, anything more is simply nonsense. Assuming you possess proficient user skills, you'll find the 'CompTIA' A+ & CompTIA Network+ programs are excellent for starters. We include information about these training programs on the section dedicated to 'CompTIA'.

Moving on you can choose to go down the Microsoft 'MCSE' or 'MCSA' path if you are considering software, or the Cisco 'CCNA' or 'CCNP' track if you are thinking about hardware. However, an in depth understanding of Microsoft's operating systems is extremely advantageous as they are such a key element of most networking environments. Again, these accreditations are discussed in depth on their respective pages within this web-site.

However, you might choose to remain down the 'ventor-neutral' track with more CompTIA certification (e.g. Server+, Linux+ and Security+ ) or maybe have a go at the wireless (Wi-Fi) aspect of things with the CWNP/CWNA.

Accreditations in this sector aren't limited just Cisco and Microsoft alone. Many well-regarded independents are today providing progressively more relevant and significant accreditations. The significance about understanding converging-technologies & inter connectivity in networks is now well accepted. We're seeing an essential generational shift within networking technologies right now, perceptions generally are leaning toward greener IT, & both processing power & data-storage are moving towards 'cloud' computing. From the financial point of view, 'greener' technology must be built to be much more cost effective, in addition to being more gentle towards the planet. The actual processing power in modern computers is lower, which means much less heat to cool down. Both of these together greatly lower the electricity expenditure, & therefore impact upon a company's bottom line -- primarily in data-centres & high-volume processing areas.

If you're especially interested in 'Messaging' or Security, then Microsoft have specialist MCSE's on offer to handle these areas. Quite possibly, the CompTIA Security+ , moving on to the CISSP ('Certified Information Systems Security Professional') might be suitable. Before choosing this route though you ought to be aware about the amount of professional experience required for the 'CISSP'. As usual, we recommend talking with an experienced IT training advisor to avoid any mishaps.
