In my 1st year Physics college course, Electric Field at a point is defined as $\vec E = \frac {\vec F}q $. However, during high school, it was defined as
An electric field is a region of space where a Coulomb force acts on a charged body placed in that region.
And Electric Field Intensity was defined as
Electric field intensity at a point in an electric field is the force per unit charge acting on a test charge at that point
The definition for electric field I am learning now seems to be what was previously defined as the electric field intensity.
My question is, what is the difference then between a field, and the intensity/strength of the field, and how can we define a field generally?
