What are Cookies? Explained in Detail?

A cookie is a text file that a Web browser stores on a user’s machine. Cookies are a way for Web applications to maintain application state. They are used by websites for authentication, storing website information/preferences, other browsing information and anything else that can help the Web browser while accessing Web servers. HTTP cookies are known by many different names, including browser cookies, Web cookies or HTTP cookies.

Mention “cookies” and most people expect a chocolate chip treat to appear. When talking about computers, however, cookies aren’t on the dropdown menu. In fact, they’re not even physical objects. Yet they do a great deal of the work that makes it more convenient for you to browse the Internet — and they can be troublesome if you don’t know how to clear or delete cookies.

Free security software just doesn’t have the resources to keep up with new threats as they emerge. That’s why you need a multi-layered defense to security. Meet Norton Security Premium — protection for up to 10 of your devices or Avast Security or Quick Heal Total Security!

Meet the computer cookie!

A computer “cookie” is more formally known as an HTTP cookie, a web cookie, an Internet cookie or a browser cookie. The name is a shorter version of “magic cookie,” which is a term for a packet of data that a computer receives and then sends back without changing or altering it.

No matter what it’s called, a computer cookie consists of information. When you visit a website, the website sends the cookie to your computer. Your computer stores it in a file located inside your web browser. (To help you find it, this file is often called “Cookies.”)

What do browser cookies do?

The purpose of the computer cookie is to help the website keep track of your visits and activity. This isn’t always a bad thing. For example, many online retailers use cookies to keep track of the items in a user’s shopping cart as they explore the site. Without cookies, your shopping cart would reset to zero every time you clicked a new link on the site. That would make it difficult to buy anything online!

A website might also use cookies to keep a record of your most recent visit or to record your login information. Many people find this useful so that they can store passwords on frequently used sites, or simply so they know what they have visited or downloaded in the past.

Different types of cookies keep track of different activities. Session cookies are used only when a person is actively navigating a website; once you leave the site, the session cookie disappears. Tracking cookies may be used to create long-term records of multiple visits to the same site. Authentication cookies track whether a user is logged in, and if so, under what name.

Are Internet cookies safe?

Under normal circumstances, cookies cannot transfer viruses or malware to your computer. Because the data in a cookie doesn’t change when it travels back and forth, it has no way to affect how your computer runs.

 However, some viruses and malware may be disguised as cookies. For instance, “supercookies” can be a potential security concern, and many browsers offer a way to block them. A “zombie cookie” is a cookie that re-creates itself after being deleted, making zombie cookies tough to manage. Third-party tracking cookies can also cause security and privacy concerns, since they make it easier for parties you can’t identify to watch where you are going and what you are doing online.
