First, you need to know what a chromosome set is. Humans have 23 different chromosomes. Scientists define this base number - the # of cs without duplication - as n. So, for humans, n = 23.
However, most organisms (including us) have two sets of chromosomes in somatic (body) cells. Than means, for most cells, 2n = 46. We get one pair of cs from our mothers and one from our fathers. It's a good idea to have this redundancy in the chromosomes, since if one cs has a bad allele copy for a gene, the other cs might have a good copy, and certain genetic disorders can be avoided.
These somatic cells are called diploid = 2n.
Germ or sex cells are different. If every time an organism reproduced, it gave a double set (2n) of cs to the child, then the child would have 4n chromosomes. To avoid this catastrophe, some cells undergo meiosis, which creates four haploid sex cells from a single diploid cell. Each haploid cell has one set of cs: haploid = n.
Recap: it has to do with the # of complete sets of chromosomes. Haploid = n = one set; diploid = 2n = two sets.

Diploid is the number of chromosomes in a full cell. In us its 46 chromosome pairs.
Haploid cells are gametes. They contain half the chromosomal information. In us our gametes have 23.

dipliod chromosomes that are made during the process of mitosis. haploid chromosomes are diploid chromosomes that are split in half during the process of meiosis.
