Absorption difference: difference between absorbance and transmittance is that absorbance measures how much of an incident light is absorbed when it travels in a material while transmittance measures how much of the light is transmitted.
Transmission difference: The transmittance t of a medium is defined by the ratio of transmitted radiant power to incident radiant power.
Similarity Between transmission and absorption: The absorbance has a logarithmic relationship to the transmittance; with an absorbance of 0 corresponding to a transmittance of 100% and an absorbance of 1 corresponding to 10% transmittance. Absorbance is a dimensionless quantity and should, therefore, be unitless.
