The less command is a program to view the content of text files. As per the less manual, less program is similar to more program, but it allows both forward and backward movement in a file and it does not read the entire input file before starting, so with larger input files less is faster than text editors like vi.
less program is the replacement of the more program. It displays the content of a file in page by page manner and thus falls into the pager program category.
