An access log contains a record of all of the files that 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 instance, all of the three files will be in the log, not only the page. An access log usually includes the date, the Operating System, the web browser and the IP address for each file in human-readable form, so you can get a good idea about the hottest files on your Internet site. The log, which is also typically referred to as "raw data", is an addition to the web statistics that you usually get with a hosting account, not an alternative. One example why you may need this type of a log is if you want to use some software on your personal computer to prepare a report about the website’s functionality, but you do not want to use the typical graphs and tables that come with the server-generated web stats.
