Web are Stateless, When The page is postBack or refresh then data is lost this means that web does not use state management,
To Keep or hold the data on the page We use State Management.
Two types of State Management.
1)Client Side
2) Server Side

1) Client Side state Management.
a) View State : To Hold the data Whatever the Page is
Refresh or Post Back occur.
b) Hidden Field : To Contain the Value
c) Cookies : To Store the Data in Local Memory of the system.when retrieve Query then give response from local memory of the system.

2) Server Side State Management
a) Session : When we open the browser and we close the browser , the mean time is known as session.
