how much knowledge of computers is mandatory for a ugc-aided degree college for the post of assistant professor of sociology
According to the latest qualification criteria of UGC for assistant professor's post, one should have SET/SLET, NET certificate and have completed his/her Master's degree successfully with minimum 55% marks.
If we talk about knowledge of computers so it is not much required and even it is not mandatory in your case because it depends upon your subject of study and you have sociology which does not involves usage of Computers.
But you should have basic skills of Computer for day-to-day life in present time.
I hope this information cleared your doubts.
