What are the key Information Technology concepts and terms:-

Firstly, you need to know which path will you start off your IT learning curve. There are many IT areas which you can expand into. For example, servers, personal desktop computing, networking, virtualization, datacenter management, programming, IT project management, IT business analysis, IT leads, etc. There list goes on. So choose your area of interest and decide. 

I will give some examples of IT concepts and terms in the server and networking area. Remember this is just the tip of the ice berg. If you are interested in server and networking. These are some of the key concepts which you will need to know. 

Windows operating system: This is the base operating platform where all the functions are performed here. Functions like opening a file, playing games, creating documents, etc

Windows registry: This is where all the operating systems' parameters reside in. You can change their settings here and you will later on, when you need to fine tune some applications or programs.

Hyper V: This is Microsoft's virtualization platform, where you can install this application into your desktop, server. And then from there create virtual hosts or virtual server and networks in this platform. Why organizations are going towards virtualization? Many companies went for it because of the hardware cost savings, on hardware maintenance cost savings, the ease of disaster recovery, the ease of doing a snap shot, the ease of backing up or creating a backup copy.

VMware: This is another virtualization platform. VMware was started/founded in 199 and later was acquired by EMC in 2004 because of its huge potential in the virtualization market. My company went for VMware and had completed our conversion in year 2006. It had its hicups during the conversion phase. But after that it was smooth saiing. But there backup function (vcb backup) is still not working that well yet. If you have many VMs (Virtual hosts) then the in build VMWare backup function will not be a suitable choice. Look for a third party backup software quick! Well this is just some concept on VMware, you can look for my articles about VMware in the site.

Cold site, Hot site: What are these you asked? They are disaster recovery terms. There are many more! But here, I will just introduce to you these two most commonly used terms first in server and network infrastructure disaster recovery. Cold sites and hot sites are alternate place where you and your colleagues can work either immediately (Hot site) or need some preparations (Cold site) when you production server and network infrastructure went down (E.g. Got burned down, earth quake, building structure instable, natural disasters, etc. For a hot site, the alternate working location will have over 90% of the information technology equipments setup (E.g. Server, Network, printers, desktops, applications, data, Internet access, etc). Employees upon activation on a disaster recovery can go to the hot site to start working immediately with little or no issues.  A cold site is where only part of the company's main IT infrastructures like critical servers, and partial network setup are ready to be used. The disaster recovery IT team will have more work to do here before employees can start working in the site.
