I am confused about find difference between knowledge and information. Give me an example.
As an example, lets take this string
The information is the answer of "What is this?". This is a string of bits.
The knowledge is the answer of "Do I understand what is a string of bits?(do I understand the information)". By the way, the best way to check if you have knowledge about something is to explain to someone who has no idea about it. If he understands it right, then you understood it right.
And as a bonus, wisdom is the way you materialize your knowledge by putting it into practice. In our example, the wisdom is the fact the you know not only what is a string of bits, but how to use it.
Neither 'knowledge' nor 'information' has a fixed, distinct, single meaning. But I think the most fruitful approach is to regard them, not as mutually exclusive, nor as identical but as points or stages on a continuum.
Someone might say, 'I want to know what's happening, just give me the information'. Here the terms appear to be used synonymously. There's nothing wrong with this but I think it fails to bring out some latent distinctions.
▻ MUTUAL EXCLUSIVITY
On this view, information is just data, discrete and disconnected. Merely having information doesn't help you understand anything. For instance, if someone gives me the information, 'A circle's radius, circumference and area are closely linked to the definition of the constant π', I accept this as information but it does not explain what this close linkage is or even tell me what e.g. 'radius' and 'circumference' mean, let alone 'the constant π'. It would be in order to refer politely to my ignorance but even to a professional mathematician it is not knowledge, only (unnecessary) information. He or she receives information but does not gain knowledge. What is received does not add to their knowledge or enable them to understand anything not understood before. It is just (useless) information.
If information is data, discrete and disconnected, it is most usefully seen, I think, as a point on a continuum on which knowledge is located too. Informational data is the growth-point of knowledge. As data is collated, connected, one item related to another, so it is systematised and synthesised into a body of knowledge where knowledge is an integrated model of some area of inquiry or activity, a model that enables and supports description, explanation and prediction.
