Every professional must have faced a dilemma at least once in their life where they are not recruited because they don’t have work experience. How can they get Work experience until they are recruited once? Thanks to simulations, folks who are in IT can at least work on a simulation of what they expect at work place. For those who intend to get into networking, there are simulations available which can simulate networks with real operating systems. For those who intend to get into Linux server administrations, Simulations are not exactly required as almost anyone can install Linux on a system or dual boot your laptop or desktop. There are still cases where you don’t want to install Linux on your working system or there is no system to install Linux on. Thank God for Raspberry Pi, a computer is in everyones reach now.
