WHAT ARE COOKIES
WHY EVERY WEBSITE WANTS YOU TO ACCEPT ITS COOKIES ?
Cookies are small files that websites send to your device that the sites then use to monitor you and remember certain information about you like what's in your shopping cart on an e-commerce site, or your login information.
These pop-up cookie notices all over the
internet are well-meaning and supposed to
promote transparency about your online
privacy.
But in the end, they're not doing much: Most of us just tediously click "yes" and move on. If you reject the cookie tracking, sometimes, the website won't work. But most of the time, you can just keep browsing. They're not too different from the annoying pop-up ads we all ignore when we're online.

These cookie disclosures are also a symptom of one of the internet's ongoing and fundamental failings when it comes to online privacy and who can access and resell users' data, and by extension, who can use it to track them across the internet and in real life.

But, for now, we're stuck with these cookie
 pop-ups that make online browsing more
difficult without accomplishing much else.
Could we click through to see what's being
tracked about us? Sure. 
And might some websites still work if we say no to the cookies? Perhaps. But most of us are just going to keep saying yes.
"We're going to be bedeviled by banners for a long time," Jerome) said.

That is a personal decision you can make site by site now that you know what cookies do.

You can control how you treat cookies with your Internet Browser privacy settings.
you probably do not want to block all your
cookies, because that would really limit the quality of your Internet experience.
You can set your browser to ask your permission before accepting a cookie though and only accept from web sites you trust.
