Difference Between Cache and Cookies (With Table)

Cache and cookies are terms that are used in computing. Cache and cookies are employed to boost the system browser performance. And also, to create additional accessible software by storing data on the client-side machine. caches store data to help the user boost the loading time. Cookies are used to store information about what you browsed.

Cache vs Cookies

The main difference between cache and cookies is that caches are for storing data to decrease the loading time while cookies are used to store user choices such as browsing history to track the user’s preferences. Cache stores data like HTML pages, flash files, etc. while Cookies stores browsing history data.

A cache stores the website contents for the long run to load web pages faster when the user wants to access the data he has already accessed before. It stores resource files such as audio and videos. The cache stores the data in the browser. Browser cache and proxy cache are two main types of cache. A browser cache is controlled totally by the user. And a proxy cache stores copies of the frequently accessed data.

Cookies stores the user’s browsing history. And then it shows you the things or products you browsed before as ads. It also stores the basic information of the user like name, email address, house address, phone number, payment card number, etc. so that the next time the user needs to add information it will automatically fill in.

What is Cache?

A cache in computing is a hardware or software component to store data. The data is stored so that future requests for that particular data can be served faster. When data can be found in the cache, the cache hits, i.e when the data is already found it is known as hit cache while if the data one is searching is not found in the cache that is known as the miss of cache.

The cache hits when the data is recounted in the cache data other than from the main server stored data. And this is why the system performs faster as the data doesn’t have to be found from other slower data stores. The data that is requested now is already requested before and the cache had stored it so the cache will make it faster to find the data now.

The caches are mostly relatively small as they can be cost-effective this way and they will also enable efficient use of data. A cache is made up of a number of entries. Each entry has an associated data that is the same data in the backing store. Whenever a user access data, it first uses the cache.

What is Cookies?

Cookies are also called web cookies, HTTP cookies, Internet cookies, or browser cookies. Cookies are small blocks of data. they are created by a web server to store user’s preferences while a user is browsing a website. Cookies are used to access websites.

One or more than one cookies can be placed on a device during browsing. Cookies contents are stored in the server and the browser. Cookies not only store the browsing history, but it also stores the tracking data, name, Email Id, phone number, Home address, pin code, etc. which are previously entered. And if the user allows it can save passwords as well.

The cookies are used by web servers mostly for authentication. It sees when the user is logged in, and with which account. Without the cookies, the users have to log in on each page that they want to access and have a piece of sensitive information.

There are two types of cookies: Transient cookies and persistent cookies. The transient cookie is also called a session cookie because it will not retain any data, it will erase it once you close the browser. Persistent cookies provide rapid access to familiar accessible data to enhance the user’s experience.

Main Differences Between Cache And Cookies

  1. Cache is installed to store the data of the website for the long run. While the cookie is there to store user choices only.
  2. Cache’s website contents are stored in the browser, while a cookie’s website contents are stored in a browser as well as in the server.
  3. Cache expires manually, i,e the user has to delete the cache while the cookies expire automatically.
  4. Cache stores the contents like HTML pages, images, flash files, and Javascript, etc. On the other hand, cookie stores the contents like browsing sessions and temporary tracking data.
  5. Cache consumes large spaces, in terms of capacity while cookies consume less space.
  6. The cache does not send the response with requests, while the cookies do.


The cache is a computing component that stores data about what the user has accessed. The data which the user is accessing is accessed before then, it makes it easier and faster to access the same data again. The data that the user is accessing is first searched in the cache and so it loads faster if it’s there.

Cookies stores the user’s preferences and browsing history. It stores data like name, email ID, phone number, etc so that the user dont have to fill in the data, it automatically fills in. And by storing data history the cookies shows the ads of the products that the user has viewed earlier.

Both cache and cookies can be deleted by the user by going into the settings of “clear browsing history”.
