An Outline of Information Science
1.1 Information Science
Definition of Information Science
Information Science is a trans-disciplinary science
with information as its object in study;
the laws in information process as its content;
information methodology as its approach; and
the strengthening human information functions,
particularly the intellectual ability,as its goal,
1.1.1 The Object,Information
The definitions of information,
Information in general is something about
the states a thing may have and
the way the states may change,
Any thing,either in world,or in mind - Popular,
Change,in motion - Fundamental,

1.1.4 The Goal
Man Nature
1,No S&T at internal evolution stage of human beings,
3,The human abilities were improved mainly through
the function division of internal organs,
2,With his own organs,man coped with the nature,

S&T emerged when the potential from internal
evolution were clearly insufficient and the external
assistance through tools supported by S&T were
absolutely needed,

IT = Computer Technology?
IT = Computer + Communication?
IT = Computer + Communication + Control?
