To Disable or Enable Cookies
If you have been surfing the Internet for any time, you have probably run into questions about cookies. With all the valid concerns about internet safety, you may wonder if these little pieces of data pose a security threat. Disabling or enabling cookies is often a choice between privacy and convenience on the web.
What Is An Internet Cookie?

Where Does The Name “Cookie” Come From?
Lou Montulli was the programmer who coined the phrase, “magic cookies,” to describe these files. Some people believe he was referring to the fortune cookies that come with Chinese takeout. These crunchy desserts come wrapped around a slip of paper with a printed message.
Are There Different Types Of Cookies?
Like in the world of pastry, there are also different types of cookies on the Internet. Read on below to learn the different kinds of internet cookies and how they can affect your browsing activities.
A session cookie is a temporary file that stores information while you explore the pages of a website. For online commerce, this kind of cookie makes it possible for your list of shopping cart items to transfer to the checkout page. This kind of cookie disappears when the session ends.
Persistent cookies are the files stored directly on your hard drive. These files let you log into several sessions without entering your password every time.
Are Internet Cookies Safe?
Cookies are text files and not programs. As such, they will not harm your computer when a website sends them. However, cookies can contain personal information such as passwords and email addresses. Someone can access your information if you access a malicious website or connect to a public, unencrypted network. It’s advisable only to enable cookies on reputable websites.

Cookies solve several problems for website developers. Without some way of sharing information, a website can’t know who you are. This lack of knowledge creates issues with the overall user experience. It also makes navigating a website with many different pages a challenge. If you click a link and the new page cannot identify who you are, it will make tasks like online shopping tedious.
When enabled, there are several common uses for internet cookies.
When a site asks if you want it to remember you or stay logged in between sessions, it generates a cookie with your username and password.

A cookie can remember your site preferences like themes and other settings.
Your shopping cart items persist from one page to the next because a cookie is holding onto the information. If you leave the site and return later, a cookie can register the items you viewed. The site will also make recommendations based on prior purchases found in the cookie.
Advertisers use third-party cookies to track the content and websites viewed on your computer. With this information, they can tailor ads relevant to you as a consumer. Some users are uncomfortable with this.

What Happens When You Enable Cookies
Enabling cookies is optional, but it’s sometimes best to enable them on reputable sites that need to know your preferences. When enabled, you’ll allow the sites you visit the chance to customize your browsing experience based on your behavior, habits, and preferences as a user.
Is It Safe To Disable Cookies?
If you are concerned about privacy, disabling cookies is always an option. However, you may find it frustrating to surf the web without the convenience these files provide. With cookies disabled, every site you land on will treat you as a new visitor. Since you cannot stay logged in to websites, you will have to authenticate your account every time. For shopping sites, you will lose shopping carts that were not yet registered to your account. Using the web without cookies is possible but negatively affects your online experience.
Why Must Cookies Be Enabled On Some Sites?
In recent years, you may have noticed more sites informing you of the need for cookies. In some cases, this may be a practical concern. Disabling cookies will impact the overall user experience. The website informs you that cookies are necessary for the best performance.
The Cookie Law
Other sites have a pop-up where you must accept the files before you can have complete access. By agreeing to use the site, you automatically consent to cookies.
