A cookie (also tracking cookie, browser cookie, and HTTP cookie) is a small piece of text stored on a user's computer by a web browser. A cookie consists of one or more name-value pairs containing bits of information.

The cookie is sent as an HTTP header by a web server to a web browser and then sent back unchanged by the browser each time it accesses that server. A cookie can be used for authentication, session tracking (state maintenance), storing site preferences, shopping cart contents, the identifier for a server-based session, or anything else that can be accomplished through storing textual data.

As text, cookies are not executable. Because they are not executed, they do not qualify as spyware or viruses. Anti-spyware products may warn users about some cookies because cookies can be used to track people or violate privacy concerns.

Most modern browsers allow users to decide whether to accept cookies, and the time frame to keep them, but rejecting cookies makes some websites unusable.

Tim Berners-Lee’s dream for his invention, the World Wide Web, is a common space where users can share information to work together, to play, and to socialize (The World Wide Web, A very short personal history). As web developers, creating business, social, and educational sites, we turn this dream into reality.
But in this period of tremendous growth, the Web needs guidance to realize its full potential. Web standards are this guidance. These standards help ensure that everyone has access to the information we are providing, and also make web development faster and more enjoyable.
Standards compliance makes it easier for people with special needs to use the Web. Blind people may have their computer read web pages to them. People with poor eyesight may have pages rearranged and magnified for easier reading. And people using hand-held devices can browse the Web just as easily as those using high-end workstations.
