This particular field is among the widest and most all encompassing sectors in the world of I.T. Generally, some level of specialisation is required, as to cover each component would probably take decades of training. Both Cisco & Microsoft make systems for this market place. The actual Network and Server software programs are produced by Microsoft, and Cisco are mostly concerned with routers & switches, that is the Network hardware. 'Security' has grown to be a huge concern recently, which has forced both organisations to move in to the area in a huge way. Equally in this field we're experiencing the substantial growth of wireless-networking. Even though Digital-Forensics and 'Ethical Hacking' have feet in all of these areas, they're also professions in their own right, and call for considerable training and real-life experience to become totally effective.

If you're looking to develop a career in IT, start by picking up a certain amount of networking knowledge. Practically nothing else will make sense until you've developed an understanding of how computers operate and link to one another. Assuming at least a basic level of PC user-skills, (see the general Computer/IT Training pages if not,) the starting point is nearly always CompTIA A+ & 'Network+' . We include information regarding these training programs on our section focused on 'CompTIA'.

Moving on from here will often take you to the Microsoft 'MCSA'/'MCSE' or Cisco CCNA/CCNP, based on whether you're pursuing the 'hardware' or 'software' end of things. Even so, it must be stated that a thorough understanding of MS networks is pretty much essential for the majority of network environments, mainly because of Microsoft's dominance in this field. Once again, these certifications are discussed in-depth on the relevant pages on this web-site.

Equally of course you could enhance your 'Wi-Fi' (wireless) skillsets with certifications like the CWNP and CWNA, or carry on down the 'CompTIA' path with Linux+, Server+ or Security+ .

Industry recognised qualifications can be attained from the vendors themselves as well as vendor neutral companies. In fact, a number of highly regarded institutions have become significant contributors now where accreditation is concerned. The understanding of network-interface connectivity between & within networks is now becoming more and more important. There are now some major shifts happening in networking - both in terms of processing & in data storage, with 'cloud' computing emerging & 'green IT' starting to be increasingly relevant. 'Green' IT doesn't particularly signify 'saving the planet' -- it does of course have many elements designed to minimise CO2 impact etc., but its also firmly placed in the economic reality of cost-savings. The actual processing power within more technologically advanced computers is lower, which means much less heat to be cooled down. Both of these together vastly cut down the energy bill, & therefore impact upon a corporation's bottom-line - primarily in data-centres and high-volume processing departments.

Several of the very best industry-acknowledged accreditations now come from the vendor neutral Computing Technology Industry Association (CompTIA). In addition there are various other companies, such as the 'ISC2' (shortened from their rather long winded: 'International Information Systems Security Certification Consortium'!) & CWNP ('Certified Wireless Network Professional'). Most conspicuously not surprisingly are Cisco and Microsoft themselves, each offering their own accreditation tracks. Mainly because of the range and quantity of qualification paths on offer in this field, it's very wise to talk through this sort of career move with an experienced advisor. Without individually-tailored guidance you might head off in the wrong direction and waste a lot of money or time.
