An access log features a record of all files which have been requested by the visitors while surfing around your Internet site. The list is thorough, so when you have a page with 2 embedded images, for instance, all of the three files will be in the log, not only the page. An access log normally includes the date, the OS, the browser and the IP address for every single file in human-readable form, so you can get a more complete picture about the most well liked files on your Internet site. The log, that's also commonly named "raw data", is an addition to the web data you usually get with a hosting account, not an alternative. One example why you might need this sort of a log is if you intend to use some software on your PC to prepare a report about the website’s functionality, but you don't want to use the regular graphs and tables that come with the server-generated web statistics.
