FASTA and FASTQ formats are both file formats that contain sequencing reads while SAM files are these reads aligned to a reference sequence. In other words, FASTA and FASTQ are the "raw data" of sequencing while SAM is the product of aligning the sequencing reads to a refseq. A FASTA file contains a read name followed by the sequence.
