Good Information:

Relevant: Information must relate to the business at hand, and fulfill the needs of the used, In theory all the information required to meet the user's purposed must be available.

Timely: information must be available when needed, Within the timeframe desired by the user.

Accurate and complete: All available information should be accessible with emphasis on the 'right' information . This often depends on the context.

Concise: Information must be understandable to those who use it, and must be able to be absorbed quickly for action.

Reduces uncertainly: A statement about the structure of an entity reduces the unknown about the entity: therefore good information should meet a user's requirements completely.

The informed decision is the best decision. For information to be useful for decision-making. it must be:

 The right information,available at the right time, available to the right person,at the right cost, presented in the right format to facilitate a decision.

Poor Information:

Irrelevant: Information is of little value when it is  too old or out-of date to b relevant to the users need.

Swamping: It is not helpful when information is too voluminous to allow any sense to be made of it. It is the quality of information that is important, not the quantity.

Unclear: Information is poor when it is not presented in a way that will facilitate a decision.

Not all threw: If information is incomplete, it may fail to provide a clear sense of the entirety of the problem.

Sources fo information: 

It has three basic elements: Primary sources, Secondary sources, Tertiary sources.

Information Literate:

In my opinion, I think it teaches us how to use information effectively that helping you to solve  a particular problem or make an important decision.

Information overload:

Help someone who get lots of information, choose relevant information and to develop skills such as  problem-solving, decision-making, critical thinking and information gathering and interpretation.

Mind Map:

Its like a map in your mind, just you know it. It has a main point , and lots of branch.
