Default Query on K-mer using in velvet

Hi, I am newbie to NGS. TO assemble a genome i started using velvet. During which I came across a term called 'K-mer' which means the overlapping segment in the reads. I would like to know that if the K-mer length assigned is suppose 21, is it that the overlapping is done exactly for 21 nucleotides at the ends or is it a minimum requirement for the reads to match? Could i kindly know the difference..Thanks in advance..
