In computing terms, a cookie is much different from the sweet treat you might associate with the name. Computing cookies are small text files sent and returned on a server. The files can then be stored on a user’s computer. They are used to identify a user or track their access to a network.
Cookies deliver websites tailored to the interests of a user. A cookie does this by carrying information from one site over to the next.
For example, if you search for vacation destinations and later see an advertisement for that destination in the next website you view, it means your computer has stored a cookie to transmit that information.
