welcome to pf!
hi girlzrule786! welcome to pf!
a point charge is a charge at a single point, as opposed to the same charge distributed over a sphere
(so eg we can use coulomb's law directly, instead of having to integrate over a volume)

A point charge is an charged entity which occupies a minute point which is an ideal case.For practical purposes we consider it is a tiny charged body and the charge at a single point where all the charge is concentrated .
we use point charges in the basic derivations of electrostatic equations which eliminates the complication of distribution and concentration of charge over the charged body.
