How to load data into Salesforce objects?

I have created my salesforce application and i have to enter my data into salesforce. I have only 5 records in one of my object, so I can simply go to tab and will create records in salesforce. But in one of my object i need to load bulk (thousands of) records, to enter thousand of records will take more time by entering manually and also it is very difficult and no one will enter thousands of records manually. Here I am providing information about how to load data into salesforce by using automated tools.

Salesforce providing two ways to load data into Sobjests. One way is “load data by using import wizard from your setup menu” and other way is load data by using data loader.

We cannot load duplicate records by using import wizard.

We can also schedule exports by using import wizard.
