Cookies are small data files that are automatically written into a host computer hard drive when certain websites are accessed. In plain terms, some websites send out digital codes that get embedded onto your computer's hard drive when you access the website.
Cookies are like a marketing tool for a website.
They contain information that the website can use to track things such as usernames and password, lists of other websites that the user has visited, and even the date the user last visited a particular website. Every time a user accesses a website with a cookie previously stored onto the user's hard drive, that website reloads the cookie file. The information that a cookie stores might be helpful to users because it can cut down on time it takes to connect to frequently visited websites. Although a cookie can be used to record the browsing habits of an individual user, it cannot by itself reveal the identity of the user. Also, there have been no known cases of computer viruses that have been transmitted by cookies.
