There can be many reasons for communicating through information

There can be many reasons for communicating through information. A purpose could be to create awareness, educate, and change knowledge of attitudes or beliefs, and to even change behaviour. Therefore it is important to identify the purpose of your communication.
Understanding the audience is important for the success of your communication. The sender needs to understand and analyse the audience so that they can adapt the message to their goals, interests and needs. Therefore this makes your information easier to understand because audience like to listen to a message that suits their interests, familiar with their level of knowledge.
Sources of information can be separated into primary or secondary. A primary source would be produced during an event meaning that the information does not already exist anywhere else. This type of information is gathered by a person directly in contact with the event so that the information is most accurate. Some examples of these would be diaries, letters, interviews etc.
A secondary source is a type of information that is filtered through someone removed from the primary event. This can includes books, interpretive documents, or an outsider’s account of an event. The Internet is a huge source of secondary information as it holds surveys, blogs etc. of peoples primary information which you could use for your own use.
