Simply put: Electronic / computer cookies

What are internet cookies? What types are there?

In their simplest form cookies are text files that are sent from a web server to a users browser. This text can be altered to store unique information which can only be read by the sender.

Session / Transient Cookie
Removed from a computer once the user closes the browser (Rouse 2005: online) and can last on a person’s computer for: a few minutes; several hours; several days if a browser is left open and the computer is in sleep mode.
Performance Cookie
Analytical purpose-based cookies find out the number of keywords or volume of visitors; they do not track users nor invade privacy.
Functionality Cookie
Personalise elements of a website, such as the language (Eijk et al. 2012:60) or the “remember me” function which allows a website to remember a username and/or password.
Targeting / Marketing Cookie
Allow advertisements to become relevant by storing users’ keywords and behaviours.
Persistent / Permanent / Stored Cookie
Useful for speeding up, enhancing user experience, or remembering details of a return visitor by staying in a subfolder until they are manually deleted (All About Cookies 2013: online): Persistent cookies can remain on a computer for several months or over ten years (Cole 1997:60).
HTTP, Flash / Local Shared Object, First & Third Party Cookies

Researchers have identified other types of, and terms for, cookies:

HTTP cookies is the collective term referring to all of the above (session, performance, functionality and targeting cookies).
Flash cookies, or Local Shared Objects, are used by websites that run Adobe Flash.
First party cookies are used to identify the relationship a user has with a specific website.
Third party cookies identify a relationship a user has with a website they have not directly visited.
