An access log contains a record of all files which have been requested by the visitors while surfing around your Internet site. The list is thorough, so in case you have a web page with two embedded images, for example, all of the three files will be in the log, not only the page. An access log typically includes the date, the OS, the browser and the IP address for each file in human-readable form, so you can get an idea about the most well liked files on your website. The log, which is also frequently called "raw data", is an addition to the web stats which you usually get with a hosting account, not a replacement. One example why you may need this type of a log is if you want to use some software on your PC to prepare a report about the website’s general performance, but you don't want to use the standard graphs and tables that come with the server-generated web stats.
