-Definition
Information overload occurs when the amount of input to a system exceeds its processing capacity
information overload is experienced as distracting and unmanageable information such as email spam, email notifications, instant messages, Tweets and Facebook updates in the context of the work environment.
-general causes of information overload
A rapidly increasing rate of new information being produced
ease of duplication and transmission
Large amounts of historical information to dig through
Contradictions and inaccuracies in available information
A low signal-to-noise ratio
A lack of a method for comparing and processing different kinds of information
The pieces of information are unrelated or do not have any overall structure to reveal their relationships
Final thoughts :
These will be the additional information for 'information overload' in my first argument.
