what is the difference between autosome and sex chromosomes
DNA is in genes, and genes are in chromosomes.
Chromosomes carry genes. Genes are inherited material that is in chromosomes. Traits are determined by the genetic information found on chromosomes.
Mitosis = doubling of chromosomes. Meiosis = halving of chromosomes.
Chromosomes are the condensed and replicated form of DNA. The two identical halves of the chromosomes are known as sister chromatids. Before division, while the chromatids are still attached, they form one chromosome. However, when anaphase (i.e the stage when chromosomes split) starts and they are separated, the two chromatids on the opposite poles of the cell become complete chromosomes.
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
At the beginning of telophase I, each half of the cell has a complete haploid set of chromosomes, but each chromosome is still composed of two sister chromatids. Cytokinesis usually occurs simultaneously with telophase I, forming two haploid daughter cells. No chromosome replication occurs between the end of meiosis I and the beginning of meiosis II, as the chromosomes are already replicated. In telophase II, the nuclei form and the chromosomes begin decondensing. The meiotic division of one parent cell produces four daughter cells, each with a haploid set of (unreplicated) chromosomes
what is the difference between autosome and sex chromosomes
Chromosomes are replicated during DNA replication, which occurs during interphase.
Do you mean what is the difference between DNA w/in chromosomes and DNA that is not? the DNA in chromosomes is tightly bound up (to histones) and therefore can not be accessed to be transcribed or replicated. Also this DNA may be methylated, or otherwise made inaccessible to enzymes that might act on it

Chromosome Nucleosome
Since the genes are on the chromosomes, segregation of the chromosomes is also segregation of the genes.
Diploid and Haploid differs in count in humans. There are 23 chromosomes in a Haploid cell while diploid has 46 chromosomes.
