Knowledge was, is and will be the most important asset of any society, person or organisation. But what exactly knowledge is? Knowledge is the saturated form of data, information and sometimes personal judgement and evaluation as well based on strong evidence. Data is the raw form of knowledge, it is collected from the target audience or platform to develop some meaningful interpretation. Data alone in its own form can be meaningful or useful. In order to make it useful, it needs to be categorised and analysed. After categorisation and analysis that data start communicating a message as it processed and data becomes the evidence of an information. Information without the evidence of data is not/less reliable. Once information is drafted from data then it is used for the intended purpose. That can be a solution to any problem or identify the reason of something. When the information is used to prove a point and information is uniformed so it can be used by others to solve their similar problems as that information becomes knowledge. Knowledge remains static until something new is identified. Knowledge has evolved over centuries and past knowledge has helped humans to develop in the future. Like in past different knowledge were created but due to lack of financial and infrastructural resources that knowledge couldn't be used. There are several examples where past knowledge along with the new knowledge is used to develop state of the art facilities. One of the examples is the wireless charging system, where the initial concept was developed by Nicolas Tesla in early 20th century. Knowledge is not developed overnight. Knowledge generation is the key to any organisation or society to move forward into future, but it's an expensive, time taking and effort oriented task. Knowledge is like the stem of a tree which bears a lot of branches(information) and leaves(data) to enhance it's importance, reliability and beauty.
