Cookies are small text files that store certain information for the browser. The term appeared thanks to Lou Montull, who was inspired by "magic cookies", which are a volume of data transferred from one program to another. It was this programmer who found the optimal solution for implementing a virtual basket in online stores.
In simple terms, using cookies, the server transmits data about visited sites to the browser installed on the PC or any other device. The transmitted information can be different. Basically, these are logins and passwords.
When a person visits a website, logs into a social network or visits a service, their browser loads the saved settings. This reduces the load on the server and helps the website load quickly.
In this article, we will look at why cookies are needed, where they are stored, and how to delete them. These files can be divided into four categories:
Temporary cookies remain in the browser and store information about you bangladesh whatsapp number database until they are closed. When a new browser window opens, the same user is considered a new visitor and must enter their details.
Persistent cookies have a set lifespan and remain in the browser until the lifespan expires or until the file is manually deleted. Websites that use this type of cookie remember users even after the browser is closed. They enable features such as persistent shopping carts, which save items added to the shopping cart between sessions.
Third-party cookies. These belong to domains. They are usually associated with advertising because they allow us to measure its effectiveness.
Zombie cookies. This type is considered prohibited, so search engines block access to sites with such cookies.
Why are cookies needed?
The main advantage of cookies is user convenience. It makes browsing the Internet more comfortable. You don't have to enter the same data for sites you visit regularly. Most websites won't work quickly without cookies.
Let's look at some examples of comfortable surfing on the Internet:
Automatic user authorization. Without it, people would have to enter their registration data every time they visit the resources they use every day. Cookies relieve the user of this routine.
Remembering data when shopping online. The "Cart" tab, which is available in all online stores, works thanks to text cookies. The items you have saved are saved even when you close the website.
Personal settings for your browser, search engines and social networks. Cookies save information about your chosen language, design, region of residence, etc. If they weren't there, the settings would be reset when you close your browser.
The second reason for the mass use of cookies is targeted advertising. If a user searched for, for example, swimming pool accessories, then the corresponding advertising will be selected for him. Cookies help the website generate a unique number based on the user's preferences.
These are the main areas where cookies are used.
We see that cookies remember the user's "route" through the site. The same web page may be displayed differently for different people.
