What is the Full Form of AFAIK?

AFAIK stands for “As Far As I Know”. 

There is a variant AFAICT “As Far As I Can Tell”; 

This abbreviation is popularly used on various social media platforms. This term is used when the sender does not have a proper or whole idea about the subject, and according to the half-knowledge he is trying to make sense. So, the sender is implying that he is sharing his perspective that is correct according to him but still doesn’t have accurate information to generate the complete sense.

It has the same meaning as IIRC that is If I Recall Correctly.

This term goes back in time, but due to the internet, it got famous quite recently. Tracing back, it has been used since the late ’90s, but due to the lack of the internet, it didn’t get a chance to pick up until recently.
