What are cookies used for?
Cookies are small, often encrypted text files, located in browser directories. They are used by web developers to help users navigate their websites efficiently and perform certain functions. Due to their core role of enhancing/enabling usability or site processes, disabling cookies may prevent users from using certain websites.
Cookies are created when a user's browser loads a particular website. The website sends information to the browser which then creates a text file. Every time the user goes back to the same website, the browser retrieves and sends this file to the website's server. Computer Cookies are created not just by the website the user is browsing but also by other websites that run ads, widgets, or other elements on the page being loaded. These cookies regulate how the ads appear or how the widgets and other elements function on the page.
What are Session cookies?
Session cookie are temporary and are erased when you close your browser at the end of your surfing session. The next time you visit that particular site it will not recognise you and will treat you as a completely new visitor as there is nothing in your browser to let the site know that you have visited before.
What are persistent cookies?
Persistent cookies remain on your hard drive until you erase them or they expire. How long a cookie remains on your browser depends on how long the visited website has programmed the cookie to last.
What are third-party cookies?
A small amount of text stored in the user's computer that is created by a website with a domain name other than the one the user is currently visiting. By default, third-party cookies are often allowed by a Web browser; however, they may be blocked, as they are widely used by advertisers to track browsing history.

If you don't want sites to store cookies on your PC, you can block cookies. But blocking cookies might prevent some pages from displaying correctly, or you might get a message from a site letting you know that you need to allow cookies to view that site.
