How do Internet cookies work?
Essentially, the cookie helps the website know that you are a specific user and take you back to the website as you left it. It is a sort of "save" function that requires no action on the part of the user. For example, cookies save certain things you do on websites so you don't have to do it every time you visit the same website.
This can be your login information, your search or watch history within the site, or anything else that could enhance the user's experience. Think of it as a week-long hotel visit. Instead of having to check in every single time you return to the hotel, the front desk gives you a key that takes you straight to your room.
Cookies are quite useful for streamlining your browser experience. It helps websites take you back to where you left off, remember your login information, preferences, and if there were any items in your shopping cart. However, there are times you may not want to keep your cookies or browsing data.
Cookies contain a lot of information about you and your browsing habits. They can keep any personal information that you put in forms. That includes your name, address, and login credentials. The same information is often used in marketing to create targeted ads for each consumer. This, admittedly, can be unsettling.
Benefits of Internet cookies
Cookies do help us in many ways that we take for granted. They greatly enhance the online shopping experience; for users who add items to their cart online and close the site, cookies help websites keep items in your shopping cart even after you close your browser.
Cookies also allow websites to save your username and password. This way, you don't have to manually enter that information each time you log in. If you've ever clicked "Remember Me" when signing in to an account, that's cookies at work.
Drawbacks of Internet cookies
While cookies mostly just make your time on the Internet more efficient and enjoyable, there are some privacy concerns that come with them. As with most things, increased convenience usually means less privacy. They also can affect your computer's speed; though cookies themselves are small pieces of data, they can take up a significant amount of storage space altogether. Blocking cookies and clearing your cache can let your computer rum smoother.
Cookies do improve your experience on the Internet, but they do so by tracking your habits online. One way that tracked information is used is through targeted ads. Some companies sell cookies to advertisers. With your cookies, an advertiser can gain insights into what kinds of ads you'll be most likely to click.
They can record device information, search history, watch history, and more or less any activity on a cookie-enabled website or browser. They don't do anything particularly notorious with this information - again, the most common use is for targeted advertisements - but nevertheless, it's a lot of information.
