What are cookies?
For modern websites to work according to today’s user expectations, they need to collect certain basic information about its users. To do this, a site will create small text files placed on user’s computers, these files are known as cookies. Cookies are uniquely assigned to each user, and can only be read by a Web server in the domain that issued the cookie to the user. Cookies cannot be used to run programs or deliver viruses to user’s computer.
Cookies do various jobs which make the user’s experience of the Internet much smoother and more interactive. For instance, cookies are used to remember the user’s preferences on sites the user visits often, to remember user ID and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve user experience.
