The most fascinating part of the computer or systems is the driving force - the Operating System (OS). I have done extensive research and testing of different Operating Systems not only to learn the pros and cons but to guide people and businesses finding the best suitable OS for their purpose. There has been so many debates about OS and getting to know them makes you realise the value of both proprietary and open source OS.
Depending on the industry, users, applications and goal OS is selected. I have been working in systems planning, architecture design, pilot testing and implementation of computer network for last 18 years. I specialise in multi-platform architecture and network designing which includes sub-netting and VLAN.
