1). DataTable A DataTable is an table which is collection of columns and rows representing with in memory.

Dataset DataSet is a collection of DataTables representing in memory. Whenever you want to fetch data from database, it connects indirectly to the database and create a virtual database in local system and then disconnected from database.

2). Dataset is a collection of tables, which is used in disconnected architecture. Generally to fill DataSet we use fill method of SqlDataAdapter. It can be used for manipulating the data remotely and finally updating the database with the modified data. This way it enables disconnected means of working with data. This improves performance in terms of reducing the number of times a database is accessed for data manipulations.

3). DataTable fetches only one Table Row(s) at a time, whereas DataSet can fetch multiple Table Row(s) at same time.

DataTable is a collection of rows and columns whereas DataSet is a collection of DataTables, performance? is based on your usage.

DataSet
DataSet is a disconnected orient architecture that means there is no need of active connections during work with datasets and it is a collection of DataTables and relations between tables. It is used to hold multiple tables with data. You can select data form tables, create views based on table and ask child rows over relations. Also DataSet provides you with rich features like saving data as XML and loading XML data.
protected void BindGridview() {
    SqlConnection conn = new SqlConnection("Data Source=abc;Integrated Security=true;Initial Catalog=Test");
    conn.Open();
    SqlCommand cmd = new SqlCommand("Select UserName, First Name,LastName,Location FROM Users", conn);
    SqlDataAdapter sda = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    da.Fill(ds);
    gvUserInfo.DataSource = ds;
    gvUserInfo.DataBind();
}
DataTable

DataTable represents a single table in the database. It has rows and columns. There is no much difference between dataset and datatable, dataset is simply the collection of datatables.
protected void BindGridview() {
    SqlConnection con = new SqlConnection("Data Source=abc;Integrated Security=true;Initial Catalog=Test");
    conn.Open();
    SqlCommand cmd = new SqlCommand("Select UserName, First Name,LastName,Location FROM Users", conn);
    SqlDataAdapter sda = new SqlDataAdapter(cmd);
    DataTable dt = new DataTable();
    da.Fill(dt);
    gridview1.DataSource = dt;
    gvidview1.DataBind();
}
