- Session can store any type of data whereas a cookie can store only standard type of data like int,float,double,string,date.
- Session has no limit and you can store any type of data in the session whereas a cookie can store a maximum of only 4KB data and overall 80KB if the browser allows a maximum of 20 cookies per website.
