This area of IT is possibly just about the most sweeping & extensive there is. Because there are so many complicated skills to embrace, some specialist training is the only logical solution. Cisco & Microsoft are the two major vendors ruling this sector. MS create Network and Server software, while Cisco focus largely on the hard-ware end of networking: Routers, switches, controllers and so on. 'Security' has grown to be a huge issue in recent years, which has led both companies to move into the market in a huge way. We should also notice the the greater professional use of WiFi these days, which is basically wireless connections and hard-ware. And lastly, two crucial and developing fields in the Security market are Computer-Forensics & Ethical Hacking.

One of the more recent sectors in this particular field is known as Digital Forensics. We might associate 'forensics' with television programmes such as CSI Miami. There could though be a bit less glamour to the real work when compared with that performed by the actors on TV! Nevertheless, technological forensics provides an intriguing job for a lot of people these days. A Digital Forensics specialist will search for and interpret digital-artefacts which are frequently utilised to solve criminal offences.

Located in a similar arena to Forensics and IT Security is 'Ethical Hacking' - another reasonably new discipline to manage criminal offences. The Certified Ethical Hacker ('CEH') and the 'Computer Hacking Forensic Investigator'('CHFI') are medium to advanced level certifications supplied through the EC-Council.

A basic knowledge of networks is a great first base for anyone getting into the IT industry. You must know precisely how PCs function & communicate with each other before you consider anything else. Providing you have good literacy skills, you will find training programs like 'CompTIA's A+' & 'Network+' offers you a very good grounding to begin your career path. These are dealt with within the CompTIA section of this web-site.

What comes next will depend mainly on whether you intend to focus on 'hardware' or 'software'. With regard to 'hardware', you are talking about 'Cisco' ('CCNA'/'CCNP'), and for 'software' you will need MS ('MCSA'/'MCSE'). That said, Microsoft has a major domination throughout most network-environments, therefore an in depth knowledge of their software is actually pretty useful whatever your specialisation. Again, these accreditations are featured in-depth on the relevant pages within this site.

Another alternative is to continue with CompTIA qualifications like Linux+, Security+ or Server+ & continue being 'vendor-neutral', or perhaps look at the 'CWNA' or 'CWNP' & specialise in wireless technology.

Industry acknowledged certifications can be acquired from the vendors as well as vendor neutral companies. In actual fact, quite a few well thought of establishments are very significant participants now where accreditation is involved. The essential knowledge of network interface connectivity between and within networks is becoming more and more important. Networking is actually going through some major paradigm shifts right now; particularly the movement towards Cloud or internet-based computing (regarding storage of data, as well as processing-power), and the mental attitude change toward 'green' I.T.. From the business point of view, greener technology must be designed to be more cost-effective, as well as being more gentle to the planet. Computer systems produce less heat (and so require less cooling) when they have lower power processors. Businesses with massive networks of computers can reduce their fuel bills significantly with greener and more efficient PC's.
