The name “cookie” has its origins in early computer terms, when “magic cookie” was used to describe a small piece of data passed between programs.
The name is still used in today’s computer lingo, but now you’ll most commonly see a cookie referred to as an HTTP cookie, web cookie, browser cookie, and internet cookie.
An HTTP cookie is a small piece of data stored on the user’s computer by the web browser while browsing a website.
Cookies were designed to be a reliable mechanism for websites to remember important information (such as items added in the shopping cart in an online store) or to record the user’s browsing activity (including clicking particular buttons, logging in, or recording which pages were visited in the past).
They can also be used to remember pieces of information that the user previously entered into form fields, such as names, addresses, passwords, and payment card numbers.
Cookies perform essential functions in the modern web. authentication cookies are the most common method used by web servers to know whether the user is logged in or not, and which account they are logged in with.
Without such a mechanism, the site would not know whether to send a page containing sensitive information, or require the user to authenticate themselves by logging in.
The security of an authentication cookie generally depends on the security of the issuing website and the user’s web browser, and on whether the cookie data is encrypted.
Security vulnerabilities may allow a cookie’s data to be read by a hacker, used to gain access to user data, or used to gain access (with the user’s credentials) to the website to which the cookie belongs.

How Do Cookies Work?
When a user visits a website, a cookie is downloaded in their web browser (such as Google Chrome) and stored as a plain text file.
Each browser stores cookies in slightly different places. When the user returns to the site, their web browser reads the file and shares the information with the domain.
There are two different types of internet cookies. Session cookies: which only collect details from single browsing sessions, while persistent cookies remain on the user’s device and collect login information over time.
How cookies work is the same across all devices and browsers — whether a user accesses a site from a Mac, PC, iPad, or phone.

However, deleting cookies does not affect passwords you saved in your browser, so when you revisit a site, your browser may automatically fill in the login page with your saved username and password.
If you turn sync on in Chrome, you’ll stay signed into the Google Account you’re syncing to in order to delete your data across all your devices.
Some sites can seem slower because content, like images, needs to load again, this is applicable when you cleared Cached Images and files.
