Cookies have, for some reason, gained a rather sinister image. But they really are simple and harmless. (Note that this question became so popular that HowStuffWorks now has a complete article on cookies.)

A cookie is just one or more pieces of information stored as text strings on your machine. A Web server sends you a cookie and the browser stores it. The browser then returns the cookie to the server the next time the page is referenced.

The most common use of a cookie is to store a user ID. For example, the cookie might containg the following string:

­ Amazon.com is one site that uses this technique. When you order a book, you fill out a form with your name and address. Amazon assigns you an ID, stores your information with that ID in its database on the server, and sends the ID to your browser as a cookie. Your browser stores the ID on your hard disk. The next time you go to Amazon, the ID is sent back to the server. The server looks you up by your ID and customizes the Web page it sends back to you. The page might say, "Welcome back, Joe Smith!"

You may be wondering:

  • Is there any more to cookies than that? No. They are simply text strings. On my machine there is a directory called c:\windows\cookies that contains all of the cookies. They are little text files -- you can open them up and see the strings that are being saved.
  • Are cookies harmful? No. They are just short text strings, and they can often make browsing better by allowing a server to recall any customized information you have set.
  • Are cookies common? Yes. There are over 500 separate cookies on my hard disk.
  • Can cookies transmit computer viruses? No. They are just text strings.
  • Can a company read my personal information from my hard disk with a cookie? No. Only the cookie that is sent in the first place is returned to the server. It is not modified or manipulated in any way.

Frequently Answered Questions

Should I allow cookies?

Cookies are small text files placed on your computer by websites you visit. They are widely used to make websites work more efficiently, as well as to provide information to the site owners. The answer to this question depends on what the cookie is used for. Some cookies are essential for websites to function properly, while others are used to track your browsing habits or serve you targeted ads. If you are not comfortable with a website tracking your behavior, you may want to disable cookies for that site. However, this may prevent the site from functioning properly.

What is a cookie on internet?

A cookie is a small piece of data that is stored on a user's computer. Cookies are used to remember information about a user's browsing session and to allow websites to keep track of a user's activities.

What are cookies used for?

Cookies are small files that are placed on your computer by websites that you visit. They are used to store information about your visit, such as your preferred language and other settings. Cookies can also be used to track your online activity, such as the websites you visit and the ads you click on. This information can be used to show you targeted ads.

Is cookies in internet safe?

It depends on various factors, including the specific cookie, the website it came from, and the user's security settings. In general, cookies are small pieces of data sent from a website to a user's computer, then stored on the user's hard drive. While cookies cannot damage a user's computer, they can potentially be used to track a user's online activity or to collect personal information. As such, users should exercise caution when accepting cookies from unknown or untrustworthy websites.

Cookies are very small text files placed on your computer by a web server when you view some sites online (not all websites place cookies). They're used to store data about you and your preferences so that a web server doesn't have to repeatedly request this information, potentially slowing download time.

Cookies are commonly used to store personal registration data like your name, your address, the contents of a shopping cart, your preferred layout for a web page, what map you might be looking at, and so on. They make it easy for web servers to personalize information to fit your specific needs and preferences when you're visiting a website.

Why Are They Called Cookies?

There are different explanations for where cookies got their name. Some people believe that the term came from "magic cookies," which are part of the UNIX operating system.

Others think that the name originates from the story of Hansel and Gretel, who were able to mark their trail through a dark forest by dropping cookie crumbs behind them.

Are Computer Cookies Dangerous?

The easiest answer is that cookies, in and of themselves, are completely harmless. However, some websites and search engines use them to track users as they browse the web, collecting highly personal information and often surreptitiously transferring that information to other websites without permission or warning. This is why we often hear about web cookies in the news.

Can Cookies Be Used to Spy on Me?

Cookies are simple text files that cannot execute programs or carry out tasks. Nor can they be used to view data on your hard drive, or capture other information from your computer.

Furthermore, cookies can only be accessed by the server that initiated them. This makes it impossible for one web server to snoop around in cookies set by other servers, grabbing sensitive bits of your personal information.

Why Online Ads Follow You Around the Web

First-Party vs Third-Party Cookies

Both types are stored on your computer and are used for similar reasons, but they're differentiated based on who created the cookie and how they're used.

A first-party cookie is created by the website you're visiting, while a third-party cookie is created by other sites through the site you're visiting. Like we said above, both types can be accessed only by the server that made it.

The use of third-party cookies isn't as obvious as first-party ones since when you visit a website, you might not assume that there are scripts handled by outside sites that are dropping cookies onto your computer. They're often created through code embedded in a third-party tool or ad. Some browsers automatically block third-party cookies.

What Makes Internet Cookies Controversial?

Although cookies can only be retrieved by the server that set them, many online advertising companies attach cookies containing a unique user ID to banner ads. Many of the major ad companies online serve ads to thousands of different websites, so they can retrieve their cookies from all of these sites, too. Although the site that carries the ad can't track your progress through the web, the company that serves the ads can.

This is where the scare of third-party cookies comes into play. But while this might sound ominous, tracking your progress online isn't necessarily such a bad thing. When tracking is used within a site, the data can help site owners tweak their designs, enhancing popular areas and eliminating or redesigning "dead ends" for a more efficient user experience.

Tracking data can also be used to give you and site owners more targeted information or to make recommendations on purchases, content, or services, a feature many people appreciate. For example, one of Amazon.com's most popular retail features is the targeted recommendations it makes for new merchandise based on your past viewing and purchase history.

Should I Disable Cookies on My Computer?

This is a question that has different answers depending on how you want to use the web.

If you go to websites that personalize your experience extensively, you won't be able to see much of that if you disable or clear your cookies.

Many sites use these simple text files to make your web browsing session as personalized and efficient as possible simply because it's a much better user experience to not have to keep entering in the same information every time you visit. If you disable cookies in your web browser, you won't get the benefit of the time saved by these cookies, nor will you have a completely personalized experience.

You can implement a partial stop on web cookies by setting browsers on a high sensitivity level, giving you a warning whenever a cookie is about to be set and allowing you to accept or reject them on a site-by-site basis. However, because so many sites use cookies these days, a partial ban will probably force you to spend more time accepting or rejecting them than actually enjoying your time online. It's a trade-off and really depends on your level of comfort.

The bottom line is this: cookies really do no harm to your computer or your web browsing experience. It's only when advertisers aren't as ethical as they should be with the data stored in your cookies where things get into a bit of a grey area and your online privacy begins to become an issue. Still, your personal and financial information is completely safe, and cookies are not a security risk.

How to Manage Cookies

There are a few ways to deal with cookies in your browser. To accept them and use them normally, you don't need to make any changes to the web browser's settings or request them from the site. Just browse normally, and if the website needs to drop a cookie, it will.

However, you do have some control over browser cookies. Maybe you want to browse the web without storing cookies, or you want to remove browser cookies from a particular website.

A web proxy is one way to use the internet without cookies being stored in your browser. Not all proxies support disabling them, though, so be sure to look for that feature. It's more common with anonymous web proxies.

Another way is to use cookies temporarily, automatically deleting them when you're done with the site. You can do that by using the website in private browsing mode.

Or, if you want to use cookies to keep your login information saved and utilize their other benefits, you can always manually delete them later. You can also clear cookies for one specific site so that the others aren't affected.

You can also see which cookies are stored in your browser. How you do this is different for every browser (and some don't let you), but in Chrome, for example, you can enter chrome://settings/siteData as a URL to jump right into those settings.

Cookies: A History

Cookies were originally designed to make life easier for web searchers. Popular sites like Amazon, Google, and Facebook use them to deliver highly customized, personal web pages that deliver targeted content to you.

Unfortunately, some websites and internet advertisers have found other uses for them. They can and do gather sensitive personal information that might be used to profile you with advertisements that seem almost intrusive with how targeted they are.

Cookies do offer quite a few very useful benefits that make web browsing more convenient. On the other hand, you might be concerned that your privacy has the potential to be violated. However, this isn't something that you should necessarily be concerned about. Cookies are absolutely harmless.
