Active factor risk vs active specific risk

Can anyone help me to explain these two terms In brief? I am confused with this.

Thanks in advance!

you have a portfolio that contains stocks from 2 industries retail and infrastructure

you change the proportion of of retail:infrastructure away from the benchmark portfolio you got active factor risk

Now each industry had stocks from 3 different industries

you kept the factor exposure same and changed the proportion of stocks within each industry you got active specific risk
