Cookies ... they are fixed-length strings of 'text' placed on YOUR computer, to facilitate the software that puts up a particular web page. A very simple example is when you see as part of a web page display: "You have visited this page 5 times" The scrap in your computer will be encoded-text identifying the URL of the web page and a text-encoded binary number. That number has just been increased by 1 somehow by the source code of web page. 'Somehow' is outlined below: . reads the web page's text cookie from a fixed spot on your computer( it knows where it is). . decodes the part of this text where it knows it has placed the #visits number. . adds +1 to the binary number . recodes the part of the text that is the #visits number. . stores the revised text cookie back into your computer into the same spot. All of the processing is done by the web source code: . get cookie . process cookie . store cookie The cookie is a fixed-length UNIX-style(literally UNIX on Apple computers) text-file that is never referenced by any application on your computer(ie- it is 'read-only' when accessed by your computer. Note that the Web page designer has no hope to create this feature without cookies. It would have to keep track of this number for EVERY web page visitor on the whole wide world web!
