Someone will laugh, but what are cookies?

HTTP cookies, more commonly referred to as Web cookies, tracking cookies or just cookies, are parcels of text sent by a server to a Web client (usually a browser) and then sent back unchanged by the client each time it accesses that server. HTTP cookies are used for authenticating, session tracking (state maintenance), and maintaining specific information about users, such as site preferences or the contents of their electronic shopping carts. The term "cookie" is derived from "magic cookie," a well-known concept in UNIX computing which inspired both the idea and the name of HTTP cookies.

Because they can be used for tracking browsing behavior, cookies have been of concern for Internet privacy. As a result, they have been subject to legislation in various countries such as the United States, as well as the European Union. Cookies have also been criticized because the identification of users they provide is not always accurate and because they could potentially be a target of network attackers. Some alternatives to cookies exist, but each has its own uses, advantages, and drawbacks.

Cookies are also subject to a number of misconceptions, mostly based on the erroneous notion that they are computer programs. In fact, cookies are simple pieces of data unable to perform any operation by themselves. In particular, they are neither spyware nor viruses, although cookies from certain sites are described as spyware by many anti-spyware products because they allow users to be tracked when they visit various sites.

Most modern browsers allow users to decide whether to accept cookies, but rejection makes some websites unusable. For example, shopping carts implemented using cookies do not work if cookies are rejected.

The cookies is a file that stored on your computer after visiting some website (eg. eBay). This is important, because it can make your life easier. Remember when you logged in to your Yahoo account? There is an option to "Remember Password", so you can access the Yahoo site and logged in without entering the username and password all the time. Worried about securities? What if my cookies are opened by a cracker and they tried to stole the password? Some cookies have encryption in it, so you can look the password by opening the cookies file directly. However, if the Cracker use your computer then logged on to your site, then destroying it/ other means, then....BAM!

However, if you have multiple browser, the cookies is just valid on that browser only. So, you may have multiple cookies from one website in your computer.

There are some kinds of cookies that used to track the user behaviour (eg. Targeted Ads), so be careful. Use some good anti spyware programs (like SpyBot Search and Destroy) to remove tracking cookies from your computer.

If you have multiple users in your computer, the cookies is just valid on the user who created it. So, don't worry if you have multiple user on your computer.

If the cookies is stolen, it can't be used on that computer, because the cookies uses the computer type, the browser type and the user to auntheticate the usages of the cookies.

Some cookies have an "expiry date", so a cookie can't be used after for certain time (as I recalled it, 2 weeks for Yahoo! accounts.). This is very important for security reasons through.

Hope that helps, Sorry for my bad english!

Cookies are small files stored on your computer that websites use to store information. For example, if you visit an online retail site like Amazon.com, cookies store information like your user name, and what items you were looking at, so the next time you visit the site it can remember your recent choices.

I assume you mean cookies on your computer. They are little files that are stored on your computer when you go to nearly any website that lets your computer know you have been to that website before.

they are files that when you sign into an site and you want it to remember you name and password they are logged into a file called cookies
